Greenhouse do it yourself from polypropylene pipes
The choice of pipes for the greenhouse due to their strength. We will not be interested in such parameters as working pressure and other characteristics for water pipes. Pipe should be plastic and solid, withstand aggressive environment and heavy weight.
TO merits polypropylene can be attributed to it environmental friendliness - pipes from it are used to supply drinking water, which means the absence of harmful impurities in the material and fumes. The flexibility of the material allows the installation of arched structures. Such pipes are resistant to high temperatures. Another advantage of them is weight - They are the lightest of all plastic pipes. Greenhouse design can be easily transferred to another place, it does not require much physical effort to create it.
disadvantages few but rather serious. With -15 ° C polypropylene pipes become brittle and can collapse under the weight of snow. The frame of them must be disassembled and removed for the winter. Such pipes ultraviolet sensitive, which reduces performance properties - they can be deformed.
HDPE pipes of polyvinyl chloride have the same virtues as polypropylenebut more resistant to UV light.
The service life of pipes - from 10 to 12 years.
To make a greenhouse with your own hands polypropylene pipes, the pipe diameter (external) can be from 13 to 25 mm, depending on the weight of the covering material. For a film, a tube of 13 mm is enough, for polycarbonate - 20-25 mm. Wall thickness must be at least 3 mm. Such parameters will provide structural strength.

How to fix on plastic frame film without damaging it? Together with arcs for the greenhouse of polypropylene pipes usually go special clipsjust pinching the film in the right places. They are plastic, so safe for its integrity. They are sold separately packs of 10 pieces. When purchasing ready-made clips, pay attention to the diameter of the pipe for which they are intended.
Can do clamps with their own hands from the scraps of the same pipes. To do this, small pieces with a length of about 7-10 cm. They are cut along the wall and moved apart. Sharp edges can be processed sandpaper or to melt.
Is it possible to mount polycarbonate on the frame?
Can. Pipes are enough durableto withstand the weight of polycarbonate sheets. But here you need to focus on expediency. Greenhouses are built from polycarbonate and polypropylene pipes with their own hands, as a rule, taking into account wintering, they are not intended for permanent assembly disassembly.
BUT polypropylene badly withstands winter temperatures. In warm regions where winter temperatures do not fall below - 5 ° СThis option is fully justified.Where frosts crack in winter, it is better to make a collapsible film-coated greenhouse.
The choice of location, design, foundation
It begins with a choice places, especially for stationary greenhouses. The construction site must be level so as not to have to complicate the construction.
It should be sunnyotherwise the meaning of its construction is lost.
Usually, a summer or stationary greenhouse is oriented with ends from south to north. So the sunlight will fill it all day.
Place must be protected from strong winds, from which steel structure may collapse.
If there is no such possibility, it is necessary to build a greenhouse so that it is protected at least from the northern wind carrying cold.
Greenhouse should be located at a distance 5 meters from other buildings on the site. Of polypropylene pipes You can build a greenhouse of any design - a house, arched, wall. The choice depends on the seasonality of use, financial opportunities and the area of the beds that are planned to be broken in it.
It also depends on what crops will be grown in it and how tall the plants will be. The most common summer design is arched greenhouse. It is aesthetic and functional.
Material for foundation and its type depends on the design. For light film greenhouses it will be enough to have a wooden base in the form of a timber or base from boards. For a permanent greenhouse with polycarbonate coating will need a more solid support.
It may be strip foundation. It is durable and suitable for removable design, if it is not intended to move around the dacha. Besides, wooden foundation will begin to rot, even if it is well treated with an antiseptic. It will have to be changed about once every 3-4 years.
Calculation of materials
amount pipes depends on the height and length of the structure, on the coating material - it will be a film or polycarbonate. For the film greenhouse, you can use pipes of smaller diameter, for polycarbonate, you need thicker, stronger pipes. In addition, to fasten the structural stiffeners, you must purchase couplings.
The calculation also includes the material from which the foundation will be made. The pipes are attached to it with metal fittings. Internal supports should also be provided. In addition, a fastener is calculated that will be used during construction.

Do it yourself: assembly instructions
How to make frame greenhouses from polypropylene pipes do it yourself? Greenhouse frame from HDPE pipes are perhaps the easiest to manufacture. For greenhouse size 10x4 you will need:
- baseboard 2x20 cm - 28 p / m,
- polypropylene pipes or HDPE diameter 13 mm - 17 pcs. 6 m each
- fittings 10-12 mm, rods 3 m long - 10 pcs.,
- strips for lathing butts 2x4 cm according to the drawing
- plastic connecting clamps,
- fasteners (nuts, bolts, screws, brackets),
- aluminum fasteners for connecting arches with a wooden frame,
- coating film
- clips for fixing the film,
- locks and hinges for air vents (if provided).
Arched greenhouse with a frame made of HDPE pipes - step by step instruction:
- Shallow (10-15 cm) is dug out at the chosen place. trench around the perimeter of the greenhouse. The wooden frame is installed in it. The bottom is covered with sand or lined with roofing felt. Bar or board for the foundation must necessarily pass antiseptic treatment for longer life. Measure both diagonals of the frame, if they are equal, it means that it is set correctly and has right angles.
- In the corners of the frame, short pieces of reinforcement no more than the sides of the frame are hammered into the ground. They will keep the design from deformations.
- The rest of the cut pieces of reinforcement are driven in half the length along the walls on the outer side of the frame in increments of 60-62 cm.
- Six meter tubes worn on pins on both sides, first with one, then with a neat bend, with the other. Attached to the base board with a metal bracket.
- From the ends is done wooden crate. 4 racks are installed. The distance between them depends on the width of the doorway. Vertical slats are necessarily cross-linked to impart rigidity.
- Under the top of the structure is pulled stiffener. To do this, using plastic clamps, two polypropylene pipes are joined and attached to the arches.
- Last step - fixing the film with the help of clips - purchased or homemade. The bottom of the cover needs to be weighed down so that the film does not rise by the wind. You can press it with stones or a long bar.
Build from pipes polypropylene greenhouse even a novice in construction can do it. It will serve more than one year, if it is properly operated and, if necessary, replace the wooden frame at the base. Good luck to everyone and good harvests!
Preparation for work
Before installation, you must stock up with the following materials:
- Polypropylene pipes with thick walls (at least 4.2 mm), designed for hot water. The most optimal are pipes whose inner diameter exceeds 16.6 mm.
- 75-centimeter rebar with a cross section of 10-12 mm.
- The edged board, the dimensions of which are equal to 150x30 mm.
- Reinforced film for greenhouses (or cellular polycarbonate).
- Square bar with a section of 50х50 mm.
- Nails and screws.
You will also need a couple of pipes of polypropylene with a large diameter (they are made of film latches and door hinges).
When crafts are made of polypropylene pipes, you can not do without tools, such as:
- hammer and drill,
- garden drill and sledge hammer
- sharp paint knife.
Selection of the site under the greenhouse
In order to mount the frame of the greenhouse from polypropylene pipes, you need to find a sunny, well-ventilated area. It is required to abandon those sectors of the site where a large amount of snow gathers during the winter season. For there is a danger that with solid loads the film sheet will simply tear. The most optimal option is when the structure can be dismantled for the winter months.
The ground for a greenhouse made of polypropylene pipes should be perfectly level with your own hands. Before construction, the upper soil is slightly tamped and leveled.
If you carefully examine the drawing of the greenhouse made of PVC pipes, it becomes clear: the installation of the frame begins with a careful marking of the selected site. A wooden frame assembled from planks must have perfectly right angles. When creating the lower wooden frame-tying used screws or nails. After hoisting the frame into place, the corners are attached to the back side with a rebar. Then the ground is filled up inside the box.
After the construction of the strapping set the most important segments of the base - reinforcing fastening rods. First, you should do the holes (here a garden drill is useful). The depth of the pits should not be less than 0.5 m. In some cases, the rods are simply hammered into the ground (for this purpose, a regular sledgehammer or hammer is taken). However, practice shows that it is quite difficult to score them vertically at once. The ends of the installed rods should protrude above the ground at 0.25 m. The step between adjacent elements is 50 cm.
On the fully finished base mounted "edges" of the greenhouse. As shown in the photo, PVC pipes are put on dug rods. Due to this, the arches get a good rigidity.
In the next stage, the PVC greenhouse is strengthened with transverse stiffeners. PVC pipes are also being manufactured. Transverse segments are fixed on the frame with wire or plastic tees. There are versions in which they are soldered to the pipe-arches. The best option is to mount them with screws.As a result, the greenhouse becomes collapsible.
The larger the dimensions of the greenhouse, the greater the number of transverse stiffeners must be installed.
The upper part of the greenhouse is certainly equipped with a central transverse "ridge" of polycarbonate. Otherwise, the film may sag under the weight of rain. With a general view of the finished greenhouses made of PVC pipes can be found by viewing the photo. You can find a detailed drawing and video instructions with step-by-step demonstration of each stage of construction.
For the construction of such elements is taken timber, pre-impregnated with antiseptics with anti-putrid additives. Collected log structures are covered with a film, which is attached to the tree with self-tapping screws.
Sometimes PVC pipes are used instead of wooden bars. The detailed drawings clearly show how and what can be made of this material. The front arches of the greenhouse are equipped with segments of the desired size. On the first arch, they are attached with tees. In the lower part of the fixation is carried out reinforcing rods.
The door assembled from the segments is hung on the finished plastic “jambs”. This is done simply: a pair of short pieces of PVC pipe with a large diameter is soldered to one of the vertical posts. Further here the door leaf is fastened.
Sheeting film and not only
Homemade greenhouse made of PVC pipes covered with reinforced polyethylene sheets. Traditional film is undesirable here, because its operational life is short. And although the cost of reinforced polyethylene is somewhat higher, it lasts much longer.
Cutting is done directly on the greenhouse. So the calculations will be accurate. The length of the strip should be slightly more "arched" ribs. The edges of the film tucked under the strapping. There it is attached to the tree through the slats. On arched "ribs" material is fixed with special plastic clips. Convenient elastic clamps are made as follows: short sections of pipes with a large cross section are cut along. Two adjacent layers of material are pushed inside the cut. There the film is fixed securely. After this greenhouse PVC can be considered built.
In addition to the classic arched shape, greenhouse PVC can have the features of a cute fairy-tale house. The base of the greenhouse is mounted similarly to the classic arched structures. The rafters here are equal plastic pieces. All parts of the frame are connected using tees-fittings. Each new upper form is “reinforced” by horizontal transverse stiffening ribs. Pre-on the ends of the supporting struts need to wear tees.

Greenhouse from plastic pipes do it yourself (video)
Experience shows: a greenhouse made of PVC pipes on its own is created quite simply. The design is going extremely fast. Such lightweight buildings cost a penny. There is no need for serious financial expenses. For its construction does not need to have special skills. To build a greenhouse of polypropylene pipes the owner of the site will be able to himself. However, it will be more fun if there are two builders. Given all the above, it is safe to say: build a neat greenhouse made of PVC pipes under the power of any amateur gardener.
Greenhouse do it yourself. Choose the material for the frame
It is difficult to imagine a modern country house without a reliable and strong greenhouse, because we love early radishes, and as children we rejoice at the first tomatoes, and in the autumn we want to get a rich harvest of heat-loving crops. All this is possible if there is a covered greenhouse complex on your site with a good construction and a durable shed.
There are many different greenhouses and a lot of materials for their construction, and therefore, opinions about what should be the best greenhouse, are also very much. One of the most important criteria for choosing one or another greenhouse is the durability of the structure, and it is from this that one should proceed when building a greenhouse complex.The most durable and, importantly, inexpensive is considered to be a greenhouse with a frame made of a profile pipe.
But if your budget is limited or you simply do not want to overpay for the installation of a greenhouse on the site, then you will certainly be interested in PVC pipe designs. The greenhouse made of polypropylene pipes with their own hands, compared with more expensive counterparts, has several advantages. One of the brightest advantages is the ability to quickly assemble / disassemble the structure, which allows you not only to choose the dimensions of the greenhouse complex, but also to fold it for winter in the garage.
Another advantage of PVC greenhouses is its lightness. However, this quality is often taken by experts as the main drawback of such structures.
Other advantages of greenhouses made of polypropylene and PVC pipes include:
Polypropylene pipes as a material for the greenhouse
Before using for the construction of the pipe from such a material, it is necessary to understand its properties, composition and other characteristics.
Polypropylene is a synthetic polymer obtained by polymerization and polycondensation reactions. In the finished state, this material has the appearance of white powder and serves for the manufacture of fittings, panels, films, plumbing and sewer pipes and other technical products.
To strengthen and increase wear resistance, polypropylene pipes are reinforced with foil and fiberglass. In the production of reinforcing layer combined, as well as made with several such layers.
Additional foil layers reinforce polypropylene tube
Polypropylene pipes have become very popular among summer residents and gardeners.
Due to its properties, this material is successfully used for the manufacture of supporting frames in buildings with a greenhouse microclimate.
The use of polypropylene pipes for the construction of greenhouses has its advantages and disadvantages.
Table: advantages and disadvantages of polypropylene pipes as a building material for greenhouses
- a greenhouse with a frame of polymeric materials has a long service life, which reaches 40 years,
- prolonged exposure to high humidity does not change the properties and qualities of polypropylene pipes, which excludes damage from corrosion. This feature is the main criterion for the choice of material in the manufacture of the frame for greenhouses and greenhouses,
- This material does not emit harmful substances hazardous to humans and plants.
- polypropylene is resistant to open flame,
- the material does not require any maintenance and additional processing,
- the frame of the greenhouse in finished form has a small weight,
- pipes made of polymeric material are resistant to repeated bending, due to which it is possible to manufacture arched structures,
- polypropylene pipes are resistant to temperature extremes. Material deformation does not occur in the range of -15 to +97 ° C,
- polypropylene has good chemical and biological resistance,
- material has a reasonable price.
- due to the lightness of the polypropylene frame, the design is unstable to strong gusts of wind,
- in case of violation of the production technology or the acquisition of polypropylene material of doubtful quality, you can face defects in the form of cracks inside the tubes and their deformation.

Greenhouse structures can be of various shapes: in the form of a cube, an elongated parallelepiped, arches or hemisphere.
The easiest way to mount an arched design. In this regard, the construction of such a form erects the majority of summer residents who do not have building skills. However, the arched structure is not inferior in its greenhouse properties to greenhouses of a different configuration.
When designing the internal arrangement of the beds, it is necessary to take care of the convenient width of the tracks and their location. The optimal distance between the fences of the beds is 50–60 cm.
With such a width, it is convenient to work with the ground, placing the inventory next to it. However, this parameter is selected individually.
Considering the specified nuances in preparation for the construction of the greenhouse, drawings and diagrams are drawn up.
Choice of pipes for construction
When choosing polypropylene pipes should be aware of the marking, indicating the conditions of use of the material.
Single-layer polypropylene pipes are made with the following marking:
- RRV - pipes, denoted by such symbols, are intended for cold-water plumbing systems and ventilation shafts,
- PPR - pipes with this marking can be used for both hot and cold water,
- PPH - for use in industrial reservoirs, as well as for cold water supply,
- PPS is the most versatile option. This type of pipe has high heat resistance.
For the manufacture of greenhouses is better to use pipes labeled PPS.
If the choice of polypropylene pipes to focus on the strength of the material, it is better to focus on multilayer pipes.
Fiberglass reinforcement gives pipes additional rigidity. It should be noted that fiberglass will make the construction of the greenhouse heavier. Unlike pipes reinforced with aluminum foil, such material does not need to be cleaned during installation.
In comparison with the pipe, in which the interlayer is made of aluminum foil, fiberglass reinforcement increases its service life by three times.
In order not to be mistaken when choosing pipes, it should be remembered that plain and reinforced materials have significant differences, which can be seen if you look at them in the context of:
- in a simple pipe the same internal and external structure,
- in the reinforced pipe you can see the layer consisting of foil or fiberglass.
Reinforced material has its own labeling:
- fiberglass tube: PPR-FB-PPR,
- foil booster: PPR-AL-PPR or PPR-AL-PEX.
Polypropylene pipes are produced with a diameter of 1.6 to 12.5 cm, in various shades.
Choosing pipes, you need to focus on quality manufacturers, which are the following companies:
For the manufacture of the greenhouse, it is recommended to choose pipes with thick walls (from 4.2 mm), the inner diameter of which is at least 16–16.5 mm, and the outer diameter - from 25 mm.
Connecting parts of the structure should be made of high-strength thermosetting plastics, the wall thickness of which is not less than 3 mm.
The need for materials for the greenhouse
Calculate the number of polypropylene pipes for greenhouses with straight walls is easy. It is enough to add the specified number and length of racks in accordance with the scheme.
Mounting an arched structure is easier than rectangular, but to accurately calculate the length of the arc, you will need to perform mathematical calculations.
Calculation of polypropylene pipes for arched design
On the Internet, the mass of online calculators that will help make calculations for the arched greenhouse. However, if the access to the network does not turn out to be at the right time, or if you are completing someone's order, which does not allow extra costs, the calculations below will help you. As an example, we will make calculations for a drawing with seven arcs.
Drawing arched greenhouse with seven arcs, where the length of one arc is 800 cm
To calculate the length of the arc, you need to remember the course of geometry of the eighth grade, namely: the Pythagorean theorem and Huygens formula.
- To calculate the length of the arc will be used known values - its width and height.
- In the diagram, the arc is highlighted in blue, inside it there are two right-angled red triangles. In each of them, one of the sides (A-D and B-D) forms an unknown value of the hypotenuse, which is indicated by the letter m. To determine the length of the arc, you must first calculate the length of the hypotenuse m of the triangle using the Pythagorean theorem: m = √b² + a²
- To determine the length of the hypotenuse (m), it is necessary to apply the Pythagorean theorem, which looks like this: m = √b² + a² = √210² + 150² = √44100 + 22500 = √66600 = 258.07 (cm).
- Now you just need to substitute the values to the Huygens formula L ≈ 2m + (2m - M): 3 Without the Huygens formula (L ≈ 2m + (2m - M): 3) it is impossible to accurately calculate the length of the arc
- We make an exact calculation of the length of one arc for the greenhouse: L ≈ 2 x 258.07 + (2 x 258.07 - 300): 3 = 516.14 + (516.14 - 300): 3 = 516.14 + 216.14 : 3 = 516.14 + 72.05 = 588.19 cm.
- Now you need to calculate the total length of all arcs. The drawing shows that there are 7 of them. Making the calculation: 588.19 x 7 = 4117.33 cm.
- The arched construction of the greenhouse will be reinforced with five transverse tubes that will play the role of stiffeners. To calculate their total length, you need 800 x 5 = 4000 cm. You will need a total of polypropylene pipes with a total length: 4117.33 + 4000 = 8117.33 cm.
Greenhouse Cover Calculation
Now it is necessary to calculate the coverage area for the arched structure. For calculations, the required length of the arc and the length of the greenhouse.
Multiplying these parameters, you can find the total area: 588.19 x 800 = 470552 cm² (47.06 m²).
The calculation of cellular polycarbonate for the roof and gables of the greenhouse is carried out on the same principle.
If a polyethylene film is used as a protective coating, then this material must be purchased with a margin. When the film is stretched over the frame of the greenhouse, there should be a minimum of 50 cm margin at its base. Subsequently, these edges will be stuck or pressed against bricks, excluding all possible gaps and gaps.
If you count with a margin of 50 cm on each side: 588.19 + 2 x 50 = 688.19 x 800 = 550552 cm² (55.06 m²).
Gable greenhouses can be made of OSB-plates or cellular polycarbonate, but if they are planned to be made of polyethylene, then this parameter should be taken into account in the calculations.
The frame of the greenhouse can be covered with polyethylene film, and the gables can be made of cellular polycarbonate
Calculation of the foundation for the greenhouse
If a type of capital base is designed for the greenhouse, then this nuance requires an exact calculation, since the concrete mix will require a different amount for each of them.
For greenhouse buildings of this type used slab, columnar, tape and tape-pile foundation. However, if a greenhouse or a greenhouse is planned to be cleaned or moved every season, then only a wooden beam frame is used for the foundation.
In our case, the calculation will be made for the concrete foundation.
For a stationary greenhouse it is better to arrange a capital base of concrete
For calculations, we need to recall the geometric formulas for calculating the volume of a cube and the volume of a cylinder.
The formula for the volume of a cube is as follows: V = h³, where h is the magnitude of the sides (length, width, and height) of the foundation. This formula is applicable when calculating slab, strip and partial tape-pile foundations.
To calculate the volume of a cylinder, you must use the appropriate geometric formula: V = π x R² x h, where π is a mathematical constant equal to 3.14, expressing the ratio of the circumference of a circle to its diameter, R is the radius of the circle, h is the height of the cylinder. This formula is applicable to calculate the volume of the column foundation.
Calculations for the specified types of foundations are shown in the examples below:
- if a slab foundation with parameters 30x300x800 cm is poured, then by example it will look like this: 0.3 x 3.0 x 8.0 = 7.2 m³,
- if the two sides of the ribbon base will have dimensions of 30x20x800 cm and two more - 30x20x260 cm, then by example it will be like this: 0.3 x 0.2 x 8 = 0.48 m³ and 0.3 x 0.2 x 2.6 = 0.16 m³. Add these values: 0.48 + 0.16 = 0.64 m³,
- if a heifer is installed on a columnar foundation with parameters of a single column 70 cm high, 30 cm in diameter, then by example it would be: 3.14 x 0.3 x 0.7 = 0.6594 m³. To get the total amount of concrete for the entire foundation, you need to multiply this value (0.6594) by the number of pillars.
Calculation of reinforcement for the foundation
So that the concrete base does not split into pieces over time, it must be strengthened. To do this, before pouring the concrete mix into a trench or excavation stack bulk metal frame of reinforcing rods. For this design, rods with a thickness of 8 to 10 mm are used.In the finished slab base design, the width of the cells should be 15x15 cm.
For the reinforcement of the foundation are used rods with a diameter of 8 to 10 mm
For the tape foundation, a three-dimensional structure of four horizontal rods is used, connected by square structures made of reinforcement with the size of 20x20x20x20 cm. For the columnar base, the same structure is used, but with the parameters of connecting elements (strapping) of 15x15x15x15cm and a length of 70 cm.
Calculation of reinforcement for slab base
For this foundation, the reinforcement will look like a grid. To determine the number of rods, you need to divide the length and width of the base by the distance between the rods in the cell:
- We calculate the length: 8: 0.15 = 53.3 pieces.
- Consider the width: 3: 0.15 = 20 pieces.
- Determine the total length of the valve. To do this, you need to multiply the number of rods by the length and width of the greenhouse. As a result, we get the total length of the reinforcement. Substitute the values: 53.3 x 3 = 159.9 m, and also 20 x 8 = 160 m.
- We add the values: 159.9 + 160 = 319.9 m, round up to 320 m.
Secrets of the construction of PVC pipe greenhouses
Greenhouses made of PVC profiles can be built in any shape:
- rectangular under a single, gable roof,
- combined from several sections
- rectangular buildings with arched roofs.
Constructive depends on the preferences of the owners, the selected project. It is important to remember that the more mates, the more docking elements are required, which leads to additional costs. It is advisable to arrange structures of small and medium size, 2-2.4 m high, about 3 m wide, 4-12 m long.
Good to know: Ergonomic width of 1 bed 800-1000 mm, walkways - 700-800 mm. Based on these parameters, it is necessary to calculate the dimensions of the construction of PVC pipes.
For the construction of greenhouses suitable PVC water pipes, standard diameter 16-110 mm, length of pipes is usually 5 m, you can buy the product in cutting: 2,3,4 m. Also on sale is PVC pipe with a reinforced layer of thin aluminum or a mixture of fiberglass with polypropylene. They are more durable, but the price is higher, for the construction of greenhouses the use of such products is not economically justified, but the owner is the master.
The optimal polyethylene pipe for the greenhouse has a diameter of 25-32 mm - for arched products, 50 mm or more - for upright supports in rectangular structures.
Homemade greenhouse made of polypropylene pipes, suitable for summer cottages
Useful characteristics of PVC pipes
The greenhouse made of polypropylene pipes is durable, does not require additional costs for special care during operation, is not afraid of aggressive atmospheric environment, due to the characteristics of the material:
- the service life of PVC pipes 10 years or more, wear-resistant,
- moisture proof, do not rot,
- not afraid of chemical and biological effects,
- don't burn
- harmful substances do not emit
- maintain considerable mechanical loadings, are not deformed,
- the material is flexible, which allows you to bend an arc of different radius independently without additional accessories.
Drawings and design features
The construction will require drawings of a greenhouse made of polypropylene pipes, it’s not difficult to make a sketch with your own hands: it’s enough to think over the form of the frame, indicating the size and valuable construction nodes. You can find a finished project on the web, adapt it to individual conditions. What should be provided if you make a drawing of the greenhouse yourself:
- what will be the foundation (foundation)
- constructive materials for pediments
- the shape, placement of the main nodes, the distance between the bearing elements,
- docking, fasteners parts.
Plastic pipes can be glued together, put on self-tapping screws, soldered with a special device, in the video we offer a practical and easy way to connect PVC pipes at home.
The easiest way to build an arched frame for a greenhouse of polypropylene pipes, cover it with film.Rectangular structures are more difficult for self-erection, additional calculations will be required, it will be necessary to provide for more stiffeners. It should also be noted that the numerous connecting nodes weaken the design.
Standard drawing of greenhouse PVC pipe
Under the greenhouse, it is better to pour the strip foundation, or lay out a platform around the perimeter of bricks, blocks, rubble stone. The easiest, fastest version of the device base - the foundation of the board 50 * 100-150 mm or timber with edges 100-150 * 100-150 mm.
We mark the area according to the drawing, hammer in the pegs, stretch the rope around the perimeter. It is recommended to remove the upper fertile soil layer, 300-500 mm in depth, by the trench. You can dig a trench around the perimeter, 300-400 mm wide, 300-700 mm deep. Level the bottom, we fall asleep with rubble - 100-200 mm, with sandstone - 100-200 mm, we tamp. We make 1-2 layers of roofing material. We process timber with refractory, antiseptic impregnations, coat with liquid bitumen, machine oil. We put the parts in the trench, check the geometry, the diagonals must be equal. Fasten on galvanized corners and long screws.
Useful advice: A stronger foundation is obtained if the ends of the timber are cut down by ½, put one into one, drill through, and tighten with bolts.
On the sides, on the top of the foundation, it is recommended to glue the ruberoid, thus providing waterproofing. Backfill the soil.
We collect the frame of the greenhouse from PVC pipes
Cut the pipe in the size of the drawing with a hacksaw for metal, grinder, we clean the ends of the file.
The first stage is the manufacture of gables. It is better to collect them on the ground, and then install them on the prepared foundation.
Pvc greenhouse door assembly scheme
We assemble the doors, you will need: 2 vertical parts, 2-2.1 m high, 3 transverse parts - 700-900 mm wide, connecting elements - 4 corners, 2 tees. The opening is made of 2 vertical posts, 1 width, as in the diagram above. Height, width of the opening should be 5-10 mm more than the door itself. On one of the racks fasten the loop.
Next, you need a PVC pipe length equal to the length of the arch of the greenhouse. We put tees on it, the distance between them should be equal to the width of the opening. We fix the opening on the tees.
A simple scheme, which is going to greenhouse made of PVC pipes with their own hands
On the long sidewall, from the outer side of the foundation we drive into the ground to a depth of 300-700 mm, depending on the softness of the soil, reinforcing, corrugated rods, 8-12 mm thick. The length of the rod is calculated individually, taking into account the fact that it must stick out 500-800 mm. The distance between the reinforcement is 600-900 mm, but not more than a meter.
How to install a greenhouse made of polyethylene pipes with your own hands, a photo of the base with fittings for fastening the frame
PVC pipe, cut into size, put on one end on the rod, bend, insert the second end on the opposite side of the foundation. According to this algorithm, we install the remaining arches.
Due to the elasticity of PVC pipe arc for the greenhouse are the same in shape
So that the installed greenhouse with its own hands made of plastic pipes was strong, we attach the arcs to the foundation with galvanized brackets, which can be replaced with wide polymer clamps.
An example of how a greenhouse is going to be made from plastic pipes with its own hands, a photo of the attachment of arcs to the base
In the same way we install the previously prepared gables of the greenhouse. It remains to tie the frame with transverse elements. We cut the PVC pipes along the length of the greenhouse and fix them on the frame with plastic clamps, as in the photo below. One transverse element in the center of the greenhouse, at the highest point of the arc, in large buildings, preferably one more from each side.

Other ways of construction of greenhouses from PVC pipes
Arched greenhouse with their own hands from plastic pipes can be built entirely on the connecting elements, but such structures will require large financial costs. Due to the frequent sections of the greenhouse of pvc pipes on the connectors more durable.
One example is how to assemble greenhouses from polypropylene pipes with your own hands, in the photo you can see the construction on special connecting elements
Similarly, a rectangular greenhouse made of PVC pipes is assembled, but in this case a material with a diameter of 32-50 mm should be used.

How to attach the film to the frame
To attach the film to the frame of PVC pipes, you can cut pieces of 50-100 mm, cut a quarter along the length, you get staples. After the film is stretched over the greenhouse, it is fixed on vertical and longitudinal stands with the latches.
Still ways of fastening a film from on the greenhouse from pipes pvc:
- mesh throughout the frame,
- with ropes
- on double sided tape stuck on the frame,
- using tapes cut from linoleum, fasten with conventional screws.
How to attach polycarbonate to the pvc greenhouse frame
For polycarbonate coating, the frame of the greenhouse is recommended to be made of PVC pipes with a diameter of 32 mm. Honeycomb sheets 4-6 mm thick will do.
Polycarbonate is fastened with self-tapping screws with a press washer of 3.2x25 mm. Surplus in an arc cut off with a sharp knife. The second sheet is attached with an overlap of the first 100 mm. It is also possible to fasten with screws a special detachable docking profile to the PVC pipe frame, insert sheets into it, close the butt with a plug.
See the reviews of the master, who made a greenhouse from PVC pipes with polycarbonate with his own hands, in the video he explains the main stages of installation and errors that should be taken into account when erecting the structure.
Greenhouse from polypropylene pipes do it yourself: design features
If you decide to make a greenhouse of plastic pipes with your own hands, and not to purchase a ready-made structure, you should decide on the type of future greenhouse. Depending on the shape of the frame, the following types of frames are distinguished:
An example of a neat construction of a greenhouse from arches of arched type using a special covering material - agrospan
- rectangular, which in turn, are divided into two types: for single and dual roof,
- combined: consisting of several sections
- rectangular design with arched roof.
For a better understanding of the types of structures, it is recommended to see photos of PVC greenhouses with your own hands. You should also read the reviews of experienced gardeners who use different types of greenhouses to learn about the advantages and disadvantages of a particular design.
Which option to give preference depends solely on your desires and preferences. There are some recommendations of experts on this issue. So, for personal use (in the event that you do not plan to grow vegetables for sale in large volumes), it is recommended to install small or medium greenhouses, whose length is in the range of 4-12 m, width not more than 3 m, and height about 2 -2.4 m
Helpful advice! For each bed, 80 to 100 cm should be set aside to provide enough space for plants to grow comfortably, as well as the possibility of convenient care for them. It is necessary to be guided by this indicator in the course of carrying out calculations.
In order for the greenhouse to have the necessary rigidity and not lose its shape under the external influence of the wind, you should use high-quality pipes with an aluminum layer
With regard to materials suitable for creating a greenhouse frame of plastic pipes, the best are plumbing PVC pipes whose diameter ranges from 16-110 mm. Along the length, you can use any pipe, usually from 2 to 5 m.
Sometimes you can find on sale plastic pipes that have a layer of fiberglass with polypropylene or aluminum. Their strength is much higher, although the cost of such pipes is quite high. It is possible to meet the statement that such investments are not justified, therefore this choice should be made from consideration of own financial possibilities.
For different parts of the structure, it is preferable to use pipes of different diameters: from 25 to 32 mm for arch-shaped elements, 50 mm and more - for elements that perform a support function, especially when it comes to rectangular structures.

DIY greenhouse made of polypropylene pipes: characteristics
Plastic pipes, despite their lightness and relatively low cost, have a lot of positive characteristics. The ease of installation and the resistance of the material to external factors makes it popular among gardeners. Consider some of the advantages of its use:
- high wear resistance: the service life of PVC pipes can reach up to 10 years,
- not exposed to moisture and rotting processes,
- fire resistant
- environmentally friendly, do not emit hazardous substances
- do not deform even under severe mechanical loads, withstand strong winds,
- resistant to chemical and biological influences.
- due to the flexibility of the material, it can easily be given any shape, bending the desired radius into an arc.
These characteristics make the use of plastic pipes in self-construction of greenhouses convenient and justified. If you correctly make all the preliminary calculations and purchase material according to your needs, you can avoid unnecessary expenses, as well as create a high-quality and reliable greenhouse with minimal financial investments.
Not only the greenhouse frame can be constructed from plastic pipes, but also shelves, doors or air vents for ventilation
Greenhouse do it yourself from plastic pipes: design features
In order to make a greenhouse of PVC pipes with their own hands, you need a drawing, or at least, a sketch. The easiest way to find a suitable scheme on the Internet, however, many prefer to draw it yourself, creating the necessary design, ideally suited for size and location in the garden or local area.
Deciding to prepare a greenhouse drawing of polypropylene pipes with your own hands, you need to think in advance what the shape of the frame will be, how large the structure should be, and most importantly, how many connecting nodes it will have. This is important because they are more expensive than all other elements. Other important aspects that need to be thought out before you start building a greenhouse with HDPE pipes yourself should include:
- the type of foundation you want to use as a foundation
- selection of materials to be used for the construction and covering of the greenhouse,
- location and shape of the main nodes,
- the distance at which the structural elements are located,
- method of fastening parts together and their docking.
Helpful advice! To connect plastic pipes together, you can use several different methods, for example, you can fasten them with screws, glue, solder or use special connecting fittings.
For the construction of greenhouses of more complex shape of PVC pipes, it is necessary to have a design scheme and adhere to accurate calculations
The easiest and most affordable option for self-manufacturing greenhouse is an arched frame made of polypropylene pipes, as a covering material for which the film is used. Rectangular structures are more complex in construction and require the most accurate calculations, as well as the presence of additional edges for structural rigidity.
Another important aspect that you should definitely take into account before giving preference to one or another type of structure is the number of joints that weaken the structure. The more of them, the less resistant the greenhouse to various influences, including atmospheric loads.
Greenhouse from polypropylene pipes do it yourself: photo instruction
The complete installation of the greenhouse construction of polypropylene pipes takes only a few hours and even one person can handle it. Although, working together is much easier and more convenient. It is necessary to carry out the assembly on a previously prepared, level ground.
Preparation of the territory for the installation of a greenhouse includes clearing the site of grass and garbage, as well as laying the foundation. For the greenhouse strip foundation is perfect, but you can also lay out the area with bricks, stones or blocks. It is even easier to use for this purpose timber or planks of 50 × 100 mm or 50 × 150 mm, depending on the size of the greenhouse.
Before starting the construction of a greenhouse, it is necessary to prepare an even and solid foundation.
To create a complete foundation, it is worth adhering to the following algorithm:
- The site is marked according to the drawing.
- Pegs are hammered in the corners, and a rope is stretched along the perimeter of the site.
- Topsoil is best removed. It will be enough to remove approximately 30-50 cm of soil.
- Along the perimeter, it is advisable to dig a trench, the depth of which will be 30-70 cm, and the width - 30-40 cm.
- It is necessary to maximally level the bottom and fill the trench with a layer of 10-20 cm in the trench and 10-20 cm over the sandstone. Further, the layers need to be compacted.
- After that one, and better two layers of roofing material are laid.
- The timber or boards that you plan to use, must be treated with antiseptic impregnation and fluff bitumen.
- After drying, they can be laid out in a trench. At this stage it is worth checking the geometry so that the diagonals and angles are equal,
- In conclusion, galvanized corners are attached and fastened with long screws.
Helpful advice! If you need to strengthen the base, then you can cut down the end of the beam half and put one in the other. For fixing it is enough to drill through both beams through and tighten them with bolts.
The box for a greenhouse can be built from boards or slate and strengthen the structure with self-tapping screws or reinforcing bars.
To provide additional waterproofing, roofing material is laid at the top and along the sides of the foundation. Only after that you can go to the backfill.
Helpful advice! For a better understanding of the construction process, it is useful to see step-by-step instructions with a photo of greenhouse plastic pipes with your own hands. In addition, a lot of visual advice can be obtained by looking at the video greenhouse PVC pipes with their own hands.
How to assemble a greenhouse frame from plastic pipes with your own hands
To make the frame of a greenhouse, you need to cut a pre-prepared pipe according to size, as indicated in the drawing. For this purpose, you can use the grinder or hacksaw for metal. In this case, the ends need to be cleaned with a file.
It is worth starting with the assembly of fronts. It is most convenient to do this on the ground, and then to install and fix ready-made elements to the foundation.
With the help of special fasteners it is necessary to secure the plastic pipes at an equal distance from each other.
Particular attention should be paid to the door, as its convenience is directly related to the comfort of your use.In order to assemble the doors, you will need 2 vertical and 3 horizontal parts, as well as 4 corners and 2 tees, which will serve to connect all the elements.
Two vertical posts with a height of approximately 2-2.1 m will be used to create an opening, on one side of which loops will be fixed. At this stage, you also need one of the transverse elements, 50-70 cm wide.
Then we take PVC pipe, the length of which corresponds to the length of the arch, and we put on it all the existing tees so that the distance between them corresponds to the width of the opening. The opening is fixed on the tees.
Helpful advice! Using tees, you can significantly strengthen the structural strength. For this, it is enough to put 2-3 pieces on the front arch and fix additional horizontal stiffeners on them.
To ensure that the covering material does not sag between the pipes, you can stretch the wire or plastic mesh and secure it with screeds
In order for the greenhouse to stand firmly, reinforcing rods, which are 8-12 mm thick, are driven into the ground. This should be done from the outside of the foundation, hammering them to a depth of 30 to 70 cm. At the same time, at least 50-80 cm of the rod should remain outside. The distance that should be observed in this case should not exceed 1 m. It is usually from 60 to 90 cm.
The advantages and disadvantages of the design. How to make and sheath the frame with your own hands. Prices and features of finished designs.
Cutting all the pipes to a suitable size, we put one of its ends on the rod and bend it so that the other end can be put on the second rod located on the opposite side of the foundation. From the second side, this procedure must be repeated.
Helpful advice!To ensure the strength of fastening, you can use wide polymer clamps or special galvanized brackets that will help securely attach the arc to the foundation. The same method can be used to mount the greenhouse gables.
For convenience, a low greenhouse can be made with an opening top, securing the two parts with a rope and chain
After that, it will be necessary only to give the frame a solid form, fastening it with the help of transverse elements. To do this, PVC pipes are cut so that their size matches the length of the greenhouse, and then fix them with plastic clamps. It is imperative that one such arc be located in the central, uppermost part of the arc. Also, additional side rails on each side will not be redundant.
By the same principle on which the doors were made, they also make vents intended for ventilation. After that, it remains only to wrap the frame of the greenhouse from the HDPE pipe with a film or sheathe polycarbonate.
What covering material for greenhouses is better: fixing features
As a covering material for greenhouses and greenhouses, you can use either plastic wrap or polycarbonate. These two materials differ significantly from each other in characteristics, methods of fastening and service life. However, each of them occupies its own niche in the modern construction of greenhouses, and have some advantages. Consider how to choose a covering material for a greenhouse.
Polyethylene film is the cheapest way to cover a greenhouse with plastic pipes.
Varieties of greenhouses
The classification of greenhouses is quite complex: they can vary in shape, seasonality, the presence and type of heating, the material used for the frame and the shelter.
A variety of greenhouse construction of plastic pipes
The most simple and reliable constructions are suitable for the manufacture of PVC pipes, including:
- wall mount greenhouse,
- gable, in the form of a house,
- polygonal, with a complex form of stingrays,
- arched, with a semicircle frame.
Wall greenhouses usually attached to the south or south-west wall of a house or other premises.The wall at the same time plays the role of thermal mass: heating up during the day, it gives off heat at night, which reduces the average daily temperature fluctuations, and also protects from cold northerly winds.
In the greenhouses of the wall creates a favorable microclimate for plants, and the cost is lower than that of stand-alone models. The main disadvantage of this design is the constant impact on the wall of moisture and the lack of good ventilation, which can lead to the destruction of the wall material.
Gable design - one of the most convenient and popular. This is due to the strength of the frame and its resistance to snow and wind loads. The reflection coefficient of gable greenhouses is low, most of the sunlight penetrates inside, which increases the lighting efficiency. Increasing the slope of the slopes, you can get the snow melting in winter, and the greenhouse does not have to shovel.
Gable greenhouses equip one or two doors, as well as vents for ventilation. The side walls of duo-pitch greenhouses can be both strictly vertical and inclined. In the second case, the illumination in the greenhouse in the morning and evening hours will be higher, which is important for temperate latitudes.
Polygonal design Greenhouses practically follow the arch shape due to several planes forming slopes and walls. Due to this, the internal space increases and at the same time the main drawback of arched greenhouses is compensated for - a large reflectance of sunlight.
It is difficult to assemble a polygonal greenhouse from pipes with your own hands due to the large number of connecting nodes; therefore, it is usually made of metal pipes by welding or from a drywall profile, assembling a frame for self-tapping screws.
Arched greenhouse - perhaps one of the most common designs, and this is easily explained: it is distinguished by strength and stability, the minimum number of connecting nodes and a large internal space. It can be made from almost any type of pipe by selecting any size and height.
The disadvantages of arched greenhouses include increased snow accumulation on the roof in winter and a high reflectance from the inclined film or polycarbonate plane.
Partial reflection is compensated by the correct installation of the greenhouse - from north to south. With this arrangement, the side walls are illuminated by the morning and evening sun, and the rays fall on the walls of the greenhouse almost at a right angle. In the daytime, when the sun is high, it illuminates the south gable and the roof, where the refraction of the rays is not so strong.
Snow accumulation is fought in three ways:
- regular cleaning
- dismantling the film for the winter or the whole greenhouse,
- shape change to lancet arch.
Greenhouses in the form of a wing arch have a more stable design, and their increased height has a beneficial effect on the microclimate: hot, overheated air accumulates above and does not inhibit plants. At the same time, the consumption of material and the area of planting do not differ from those of conventional arched greenhouses.
PVC pipes and methods of their connection
PVC pipes are designed for installation of cold water supply systems and can be operated at temperatures up to +65 degrees. Thanks to flexibility and a wide variety of connecting elements, it is easy to assemble a greenhouse of any configuration from them.
For greenhouses use PVC pipes with a diameter of 20 to 32 mm, they provide the necessary rigidity of the frame. Standard pipe lengths can be 1, 2, 3 or 6 meters.
PVC pipes for greenhouses can be connected in several ways:
- using clamps, screeds,
- on furniture bolts on pre-drilled holes,
- on glue.
When connecting pipes to the clamps or bolts, the greenhouse can be completely disassembled and moved to another location, ensuring crop rotation. In this way, film greenhouses and greenhouses are more often installed. The film for the winter is usually removed, to avoid its damage by snow and wind, at the same time disassemble the frame.
One way to fix PVC pipes
Glue joint is obtained non-separable, but more durable. It is recommended to use it for the greenhouses established on the base and left for the winter. They cover such greenhouses, as a rule, with polycarbonate - it serves at least 5-7 years and does not require annual replacement.
Connecting elements for PVC pipes used in the installation of the greenhouse:
- cornersallow you to mount mutually perpendicular elements,
- tees - connect three pipes in the same plane or at an angle (single-plane tees can have an angle of 45, 66 and 90 degrees),
- crosses, for connecting four tube elements.
PVC pipe fittings
The number and type of fittings used depend on the greenhouse design, as well as the selected type of connections.
The procedure for connecting pipes and fittings to glue
The connection is made on glue Tangit PVC-U company "Henkel" or its equivalent. This glue provides strong fastening of parts and quickly hardens, so installation does not take much time.
Tangit PVC Kleber
- Cut the pipe to the required length with a cutter, hacksaw or scissors. Check the compatibility of the pipe and the fitting: the pipe should enter into it 2/3 of the socket length.
- To clean the edges from burrs, remove the chamfer from the end with a knife.
- Degrease the joining surfaces with any solvent. Apply glue to both glued surfaces: the pipe and the inner surface of the fitting.
- Insert the pipe into the fitting strictly along its axis at 2/3 of the depth to the stop, then rotate 90 degrees inside the fitting so that the glue is evenly distributed.
- To fix them in this position for 15-30 seconds, then wait another 1-2 minutes until full adhesion.
Pipe glueing procedure
The procedure for connecting pipes to the bolts
Furniture bolts with a diameter of М6 or М8 are chosen as fasteners, depending on the diameter of the pipes. The length must be sufficient to connect the two pipes.
Coupling furniture bolt
- In the pipes, prior to installation, mark up the space for re-drilling holes.
- Drill through holes with a drill 2 mm larger than the diameter of the bolts.
- Connect the pipe, aligning the holes. Insert and tighten the bolts.
The scheme of drilling holes with the help of a simple wooden conductor
Holes can be drilled and in place, while the pipe is temporarily fixed on the wire tie or fixed in another way.
Types of greenhouse complexes of plastic pipes
There are many modifications of greenhouses, we present only some of the most common ones:
- Arch greenhouses with a durable film coating (can be equipped with a box of wood and arcs on steel rods, as well as arcs and a frame of plastic on tees).
- Models with a gable roof film coated.
- Design arch type with polycarbonate casing.
- Products equipped with a gable roof and cover polycarbonate.
Materials for self-construction
In order to construct a greenhouse with your own hands, you will have to arm yourself with an aluminum profile, polypropylene or metal-plastic pipes, as well as PVC pipes. The status of a truly durable and super-reliable complexes deservedly won products based on shaped pipes. Traditionally for the construction of pipes used with a rectangular or square section (40 x 20, 20 x 20, 40 x 40).
The framework of the construction on the basis of shaped pipes is the best suited for the subsequent glass plating. Many gardeners prefer greenhouse complexes of galvanized pipes. Of course, such products have several advantages: the frame does not rust and deteriorates from corrosion, successfully withstands any vagaries of weather, and the service life of such a design goes back decades.
To accurately calculate the amount of materials needed, you must first design the structure. This is done either independently, with the availability of relevant knowledge and training, or simply downloaded from the Internet.
Attention! Anyone who wishes can construct a greenhouse on the basis of plastic pipes: from a professional builder to a beginner who never once had a tool in his life. The main thing - the desire, patience and utmost accuracy!
For the work we will need fittings, PVC pipes, 4 beams 10 x 10, bars 50 x 50 in the amount of 10 pieces, plastic clamps, nails, screws, several polycarbonate sheets, components for air vents and doors of the future design, as well as some free time and desire.
Construction work, as usual, is preceded by an important stage of preparatory activities: the site for construction is selected and carefully leveled. The timber is necessarily treated with a special antiseptic, which will preserve the original quality for a long time and protect it from moisture and the effects of the soil. Using a bar, the frame of the base is neatly made.
To give the construction maximum stability, reinforcing bars are used. Of these, special blanks are cut to a length of no more than 80 cm. They are driven in along the entire perimeter of the future greenhouse at a distance of 50 cm from each other and to a depth of 40 cm. On the left side, a PVC pipe is put on the reinforcing rod and gently bent. The second end is put on the rebar located on the right. As a result, arcs are obtained at an equidistant distance from each other (50 cm). The pipes are fixed very simply: they are screwed to the base frame on the clamps. We will need 50 x 50 bars for the construction of openings for future doors from the end of the greenhouse.
In order for the finished structure to be really strong and as durable as possible, it is recommended to install stiffeners. For this purpose, a pipe is fixed in the central part of the end blocks and is fixed to all arcs by means of clamps.
Doors are installed in the prepared doorways. The simplest construction of the greenhouse is considered finished
We select trim
It is impossible not to agree that the film is the most common coating. Yes, at first glance it may seem that the cost of film coating will be minimal. However, looking into the near future, we note that a new film will have to be bought every season, which means that costs will only grow every year. If this does not scare you, then feel free to buy this inexpensive cover and gently fasten it along the bottom edge of the structure. Then the film rises, gently stretches, with the help of rails nailed in the middle, again stretched and fixed in the lower plane on the other side of the greenhouse. The whole procedure will take about 1-2 hours. The main thing is to do everything slowly and very carefully. To install the film, choose windless weather whenever possible.
Despite the many advantages, the greenhouse complex with a glass coating is a somewhat expensive business. For the construction of a good and durable greenhouse it is necessary to prepare the foundation, weld the base of the profile pipes, carefully work out the watering and ventilation of the air, glaze. The last stage - glazing - requires special skills and abilities from the performer, because the material is quite fragile and unsafe. Yes, and hooligans divorced a lot: inadvertently can damage not only the design itself, but also ruin the entire greenhouse crop.
If you are interested in a really practical, reliable and durable coating, then use polycarbonate. This versatile material winters excellently, does not need to be dismantled at low temperatures, and in the spring in such a greenhouse almost instantly thaws the ground. The coating retains heat, condensate is never visible on it, and the service life of polycarbonate reaches 10 years. No wonder experts consider it the best cover for modern greenhouse complexes.
Fastening polycarbonate to the frame is a simple procedure that does not take much time.
To cover the structure with polycarbonate, you first need to unfold it (material is sold in rolls), remove the protective film from the bottom surface and fix the canvas on the bottom of the screws. Then the sheet is carefully lifted and simultaneously screwed to the frame every 70 cm. Reaching the opposite side of the greenhouse, the sheet is fixed again at the bottom. If the greenhouse is installed perfectly even, then the coating will be smooth and uniform over the entire surface.
In addition to the above materials for plating, you can use non-woven materials (spunbond, agrospan, agrotex). Bubble film coatings and reinforced that are able to withstand any bad weather, including major hail and gale, are very common.
As you have noticed, it is not only easy to build a greenhouse of PVC pipes, plastic or polyethylene pipes, but also available even within a limited budget. Inexpensive and properly constructed greenhouse of PVC will last for a long time and will be an excellent alternative for expensive greenhouse complexes manufactured in the factory.

There are no sizes. The diameter of the pipe and fittings are very interesting. For example, pipes F25, which crossings are necessary for them, crossings F32 are too big for them.
The amount of reinforcement for the column base
- Determine the length of the reinforcement for the manufacture of vertical frame elements for one column: 0.7 x 4 = 2.8 m.
- Calculate the length of the reinforcement required for the manufacture of one element of the frame binding: 0.15 x 4 = 0.6 m.
- We determine the length for three elements: 0.6 x 3 = 1.8 m.
- We calculate the length required for the manufacture of reinforcement cage for one column: 2.8 + 1.8 = 4.6 m.
Calculation of reinforcement for strip foundations
To determine the total amount of reinforcement in this foundation, it is more convenient to do the calculation for each side separately. We consider sides of 800 cm each:
- Since the three-dimensional structure consists of four horizontal rods and connecting elements, it is necessary: 800 x 4 = 3200 cm.
- For two sides you need: 3200 x 2 = 6400 cm.
- Now you need to determine how many connecting elements fit into this length (800 cm). The distance between each of them should be 30 cm. We substitute the values: 8: 0.3 = 26.7.
- For two such parties you need: 26.7 x 2 = 53.4 pieces.
- Now it is necessary to find the length of the reinforcement for the manufacture of one connecting element: 0.2 x 4 = 0.8 m.
- We multiply this value by their total number: 0.8 x 53.4 = 42.72 m of reinforcement will be required for the manufacture of connecting elements for both sides with a length of 800 cm.
By the same principle, the other two parties are calculated:
- 300 x 4 = 1200 cm is the length of horizontal bars for a side of 300 cm.
- 1200 x 2 = 2400 cm is their total length in two sides.
- 3: 0,3 = 10 pieces - this is the number of connecting elements in the side, equal to 300 cm.
- 10 x 2 = 20 pieces - this is their total number in two such sides.
- 20 x 0.8 = 16 m is the length of reinforcing bars needed to make connecting elements for two sides.
- Now it is necessary to calculate the total amount of reinforcing material for the entire perimeter of the foundation. Calculations will be made in meters. For this it is necessary to add the obtained values: 64 + 42.72 + 24 + 16 = 146.72 m of reinforcement will be needed to strengthen the strip base.
The need for other materials for the greenhouse
In addition to these materials, you will need the following:
- wire or fittings made of polymeric materials that will serve as connecting elements for the polypropylene frame,
- reinforcing bars with a diameter of 10 to 12 mm and a length ranging from 70 to 90 cm, to which the frame of the greenhouse will be fixed,
- wooden bars with a section of 100x50 mm, if you plan to make a light base.
During the construction of the greenhouse can not do without the following tools:
- garden drill
- sovok and bayonet shovel,
- measuring tape,
- stakes with cord
- sharp knife
- soldering iron for plastic pipes,
- welding machine
- concrete mixer,
- construction hose for the supply of concrete mix,
- large square,
- plumb line
- building level
- electric drills,
- a pencil.
Step-by-step instructions for building a greenhouse made of polypropylene pipes with your own hands
When all the necessary drawings and diagrams have been made, the calculation has been made and the necessary materials have been acquired, one can proceed to the direct construction of the greenhouse. For the construction of the chosen arch design on a tape base with a protective coating of polycarbonate.
Stages of construction of the greenhouse imply the following construction activities:
- On the selected site you need to make markup. For this it is convenient to use a tensioned cord. You must ensure that the intersection of the cord formed an angle of 90 degrees. To determine the correct markings, you need to tie the cord segments to opposite stakes so that they intersect in the center of the perimeter. If the intersection is strictly in the middle, then you can be sure that the marking is done correctly.
What film is better for a greenhouse, and how to attach it to the frame
There are several ways of attaching a plastic film to the frame of a greenhouse, among which it is worth noting the simplest and most convenient: the film is cut into pieces, 5-10 cm in size, and a quarter is cut along the length so that the staples are obtained. The film is stretched onto the greenhouse, and with the help of the brackets obtained is fixed to the longitudinal and vertical posts.
Other options for fixing the film include fixing with ropes, netting across the frame, using double-sided tape, and even ordinary screws. The latter method will require small pieces of linoleum, which will protect the film from damage. You can buy clips for films on the greenhouse, which are sold in specialized stores and not only provide a reliable mounting cover, but also greatly simplify the work.
The main advantage of this method is the low price of film for greenhouses and greenhouses. Such coverage does not last longer than one or two seasons, however, there are no problems with its replacement. By purchasing a roll of film for a greenhouse with a width of 6 meters, you can be sure that it will be enough for several seasons of use.
The covering material can be fixed on the greenhouse using stationery binders, double-sided tape or pipe holders.
Helpful advice!In order not to collide with drafts in the greenhouse during operation, it is recommended to make the film longer than the frame in such a way that approximately 10-20 cm remains lying on the ground. In this case, the edges can be sprinkled with earth or laid on top of the board, in order to ensure greater tightness to the structure.
Most often, acrylic film for greenhouses is used as a covering material. The indicator of its strength is higher than that of polyethylene, and therefore its service life will be much longer. Although it is worth noting that the price of an acrylic film for a greenhouse is somewhat higher.
How to choose a polycarbonate for a greenhouse: methods of attachment
Polycarbonate is another covering material for a greenhouse, which can be bought at any hardware store. Before you buy, you need to think about exactly what sheets are needed, and how to fit the materials together.For example, in order to attach polycarbonate to the frame, the frame should be made of polypropylene pipes with a diameter of at least 32 mm.
Cellular polycarbonate and a connecting demountable profile for fastening
It is believed that cellular polycarbonate, whose thickness is within 4-6 mm, has ideal technical characteristics for covering the greenhouse. Acquire a thinner coating does not make sense, since it can not cope with external loads.
Polycarbonate is attached to a PVC greenhouse as follows:
- Using self-tapping screws and washers 3.2 × 25 mm, the material is attached to the frame.
- With a sharp knife, the excess is cut off in an arc.
- Each next sheet is attached with an overlap of 100 mm to the previous one.
- To strengthen the structure, a special detachable docking profile is used, which is fastened with screws. Sheets of polycarbonate are inserted into it.
- The joints are closed with plugs.
You can make a hinge for a greenhouse PVC pipes with their own hands. To do this, from a pipe of larger diameter cut into two pieces of 10 mm and connect them together with glue. Sheets of polycarbonate are inserted into them and fixed with the help of the same screws. This is very convenient for creating vents and door elements.

Greenhouse from polypropylene pipes do it yourself: video instruction
To make a greenhouse from polypropylene pipes is quite simple. Adhering to all the recommendations and instructions, you can create a solid and beautiful design that will be an excellent addition to the site and will allow you to grow seedlings, vegetables and greens. The main thing is to choose the right materials and ensure their reliable bond between each other.
Calculation of the necessary materials
First you need to decide on the shape and size of the greenhouse (length, width and height). As a rule, in the greenhouse have two beds, separated by a passage. The width of the beds usually varies between 0.8-1.1 meters - this allows you to plant two rows of plants with the necessary spacing and provide easy access to them.
The width of the passage should be such that you can walk freely with buckets and other garden tools, including a wheelbarrow. Usually the path is made 0.6-0.8 m wide. As a result, the width of the greenhouse will be 2.2-3 m.
The length of the greenhouse depends on your needs and the placement rate of vegetable crops that you plan to grow in it. Planting rates per 1 m 2 of the greenhouse area are given in table 1.
Table 1. Planting rates of vegetable crops in the greenhouse.
Based on these standards, determine the length of the greenhouse. Typically, the length is 3-6 meters - putting a smaller greenhouse is impractical, and for structures of greater length it is better to use more durable materials and capital construction technologies.
Note! If you plan to use polycarbonate as a greenhouse cover, choose a length that is a multiple of the width of the sheets (2 meters). So you will avoid unnecessary scraps.
The height of the greenhouse should allow it to move freely in it, in addition, at least 50 cm of free space should remain above the plants - hot air accumulates there and air exchange takes place during ventilation. For undersized crops — pepper, eggplants, undersized tomatoes — a height of 1.8-2.0 meters is sufficient. For tall crops, the height of the greenhouse must be at least 2.2-2.4 meters.
Designing a greenhouse and calculating costs (for example, using polypropylene pipes)
Another important parameter for an arched greenhouse made of pipes is the arc length, which is found by the formula:
Formula Calculations for Arc Length
Here L is the length of the pipe for the arc, m, h is the height of the greenhouse, m, B is the width of the greenhouse, m. Table 2 shows the dimensions L for the most commonly used sizes of greenhouses.
Table 2. The length of the arc for greenhouses of standard sizes.
To calculate the materials it is also necessary to determine the step between the arches.If you plan to remove the cover from the greenhouse for the winter, it is enough to arrange the arches with a pitch of 0.8-1 meters. For a non-separable structure, the step should be reduced to 0.5-0.7 meters - this will save the greenhouse from deformation under the influence of snow.
It is necessary to take into account the material for the manufacture of longitudinal screeds, end walls, doors and vents. The total length of the longitudinal screeds can be calculated by multiplying the length of the greenhouse by the number of screeds. Usually there are at least five of them: two lower, two lateral and ridged. To strengthen the design, you can use additional side braces.
On the end walls you will need pipes with a total length of 15-20 m. On each door you need about 5 meters of pipe, on the window leaf - 2-2.5 meters. For convenience, you can create a detailed sketch, which shows all the dimensions, as well as the number of connecting elements.

Step by step assembly instructions arch greenhouses
Below is a step-by-step instruction on how to assemble a greenhouse made of PVC pipes with the following dimensions:
- width - 2.4 m,
- height - 2.0 m.
- length - 4 m.
Table 2 determines the length of the arc - it is 3.8 m. For the framework, use PVC pipes of standard length 6 m with a diameter of 25 mm. Such pipes will ensure the construction of reliability and rigidity. To connect the pipes, standard 25 mm fittings and glue joints are used.
On the greenhouse of the specified sizes with two doors and window leaves and with an arrangement of arches of 67 cm you will need:
- PVC pipe L = 6 m, Ø25 mm - 16 pieces,
- single-plane spider Ø25– 5 pieces,
- tee single plane angle of 90 degrees Ø25– 28 pieces,
- tee single plane angle of 45 degrees Ø25– 4 pieces,
- tee two-plane Ø25– 4 pieces,
- corner of 90 degrees Ø25 - 16 pieces,
- self-tapping screws or furniture bolts for fastening side screeds - 36 pieces,
- two-clamps - 18 pieces, to them self-tapping screws 55 mm - 36 pieces.
- door hinges - 8 pieces, for them self-tapping screws 24 mm - 48 pieces,
- polycarbonate - 3 sheets of 2x6 meters,
- self-tapping screws for fastening polycarbonate with a thermal washer - 100 pieces,
- connecting profile for polycarbonate or building tape.
A film can also be used as a greenhouse cover, it will take about 8 meters long with a width of 6 m.
Ground planning and foundation installation
In order to avoid construction skewing during installation and operation, the area under the greenhouse must be pre-leveled. To do this, mark the location of the future greenhouse on the ground with pegs and twine and check the plot level. With a slope of more than 1 degree, the area must be leveled It is recommended to make a sand pillow 5-10 cm thick under the foundation.
As a basement for greenhouses, a wooden bar with a section of 10x10 cm is traditionally used. It provides load distribution and serves at least 10-15 years, while it is inexpensive, and its installation does not take much time.
Bar 100x100 mm
Step 1. The timber is cut to the size of the greenhouse, impregnated with antiseptic for the lower rims of the log house or waste oil and dried. Treatment with an antiseptic is more convenient with a sprayer.
Step 2. Gather the foundation on the site for the greenhouse, laying out the timber on a sand pillow or auxiliary bricks made of bricks, while using the level. Check the dimensions, as well as diagonals - with proper installation they should be equal.
Step 3. Connect the bars with metal corners and screws. When the length of the bars is insufficient, they are fastened with staples. For better adhesion with the ground using metal pins - grouser. All fasteners should have a protective coating, it is best to take galvanized elements. After the foundation is installed, they can be additionally painted or varnished.
Connecting elements for timber
Step 4. Pour sand around the perimeter of the foundation, finally fixing it. In this case, you can immediately run tracks in the greenhouse and the fence of the ridges.
Bookmark tracks and ridge markings
Greenhouse frame assembly
The assembly of the frame start with the preparation of the required sections of pipes. After cutting to size, it is better to sign them with a marker so as not to get confused.
For the described construction you will need:
- 400 cm long pipe lengths - 2 or 4 pieces,
- pipe length 190 cm - 10 pieces,
- 180 cm long pipe sections - 4 pieces,
- pipe length 140 cm - 4 pieces,
- pipe length 76 cm - 8 pieces,
- pipe lengths of 65 cm - 18 pieces,
- 46 cm long pipe sections - 4 pieces,
- pipe length 10 cm - 4 pieces.
The remaining elements, including the frame of the doors, air vents and end couplers, are cut out in place during installation.
Stages of installation of PVC greenhouses
Step 1. Pipes for five intermediate arches 190 cm long are glued in pairs using crosses. In the illustration, the connections are highlighted in blue.
Step 1. Connecting the intermediate arches
Step 2. The end arches are connected according to a scheme of four pipe segments and three tees. Two 140 cm long pipes form side arcs that are attached to the tees with an angle of 45 degrees so that when the arch is bent into an arc, the free sockets of the tees are directed downwards - the door apertures will be attached to them. The 46-cm-long pipe pieces are connected to a 90 degree tee, then the parts are combined into a common construction, while the side socket of the 90 degree tee should be directed perpendicular to the axis of the 45 degree tees.
Step 2. Connecting the end arches
Step 3. Collect the two lower side ties of six pipe lengths of 65 cm and five single-plane tees for each tie. The conclusions of the tees are directed strictly in one direction - arcs will be attached to them.
Step 3. Connect the bottom side screeds
Step 4. Collect two end couplers of three lengths of pipe 76 cm and two single-plane tees for each tie.
Step 4. Connecting the bottom end braces
Step 5. Assemble the doorways according to the scheme. Fix the 1.8 m long pipe segments in the lower tees, then connect them with the help of tees and jumpers with a length of 76 cm. Pieces of about 10 cm long are glued to the tees - a continuation of the racks. Later they are cut to size when connected to the arch.
Step 5. Assembling the doorway
Step 6. Gather end walls. Connect the end fasteners and end arches with the help of tees and racks, as well as two-plane tees at the bottom. The pipes at the top of the racks are cut to size.
Step 6. Assembling the end walls

Step 7. Collect frame greenhouses on the foundation. Install one end arch and connect it to the bottom ties. Install the first intermediate arch in the tees on the lower ties and connect it to the end with a jumper 65 cm long. Consistently fix all the intermediate arch. Install the second end wall, connecting it with the upper and lower side ties. For stability during assembly, temporary wire ties can be used.
Step 7. Build the frame (side view)
Step 8. Check the diagonal of the frame, if necessary, align it. Fix the frame on the timber with the help of metal two-clamps and screws.
Step 8. Fastening the frame to the timber
Step 9. Install side tie. They are attached to furniture bolts at a height of about 1.4-1.6 meters on both sides from inside the greenhouse. For greater rigidity, additional longitudinal ties can be fastened. The place of fastening of bolts is marked with red crosses.
Step 9. Install side screeds (side view)
Step 10. Assemble the doors and vents in accordance with the scheme of scraps of pipes, tees and corners. Secure the vents to the door frames on the hinges with screws. Attach hinges on the door frame.

Alternative option - design without kinks
Polycarbonate is a relatively new material that has been widely recognized by summer residents.
It has many advantages:
- good light transmittance
- a two-layer honeycomb structure that retains heat well,
- sufficient mechanical strength
- UV resistance,
- simple and quick installation
- service life of at least 5 years.
- reflects the sun's rays stronger than glass and film,
- resistant to scratches and punctures, requires careful handling,
- if improperly mounted, moisture and dirt accumulate inside, causing the material to dull.
To extend the life of the polycarbonate must be installed strictly with the recommendations of the manufacturer.
Polycarbonate strength characteristics
Three important factors to follow:
- polycarbonate is fixed so that moisture can flow along the internal longitudinal strips,
- one side of the polycarbonate has a protective UV coating, during installation, sheets must be placed this side up,
- fastening is carried out on special self-tapping screws on the pre-drilled holes, otherwise, when heated, the sheets will lead.
Standard mounting scheme for polycarbonate
Step 1. Remove the protective film from the polycarbonate and mark the upper side with a marker (on it, the protective film is usually colored or has a manufacturer's logo). It is better to make a few marks on each sheet.
Removing film from polycarbonate
Step 2. Polycarbonate is cut out for end walls. To do this, the standard sheet is cut into three pieces measuring 2x2 meters. Apply one piece to the end of the greenhouse so that the cavities are directed vertically. Align the left side of the sheet along the left edge and outline the contours of the arc to the left upright and down it with a marker. Apply the right edge of the sheet to the right side of the end and act similarly. As a result, the sheet produces the contours of the two semi -ars. Cut them with a knife or electric jigsaw with a small allowance of 3-5 cm. This is also done with the second end.
Step 3. Fix the cut parts on the screws with thermal washers using a screwdriver. The mounting step is 30-50 cm. At the same time, they try not to pinch the polycarbonate. Trim the excess polycarbonate with a knife.

Step 4. The third piece of sheet is used for door trim and vent windows. Sheet applied to the door, observing the vertical. Circling the door with a margin, cut out the workpiece and fasten them on the doors and vents. From the remnants of polycarbonate cut the arch over the door, close it. Polycarbonate at the joints is better to combine with the help of special profiles.
Polycarbonate Compound with Profile
Step 5. Close the top of the greenhouse. To do this, a sheet of polycarbonate is laid over the arcs, aligned along one of the lower edges, and the second is trimmed in place. The sheet should protrude slightly above the ends of the greenhouse. Fix the sheet in the corners.
Laying the first sheet
Step 6. Impose a second sheet overlap on the first in place of the joint, pruned. Fix the corners of the sheet, then fix the screws on the bottom and all the arcs with a step of 40-60 cm.

The use of the film as a covering material has its pros and cons.
The advantages of this coating include the following factors:
- low price
- easy installation
- good light transmittance.
- low mechanical strength
- susceptibility to UV radiation, because of which the film is destroyed in a year or two, even without mechanical effects,
- low thermal insulation.
Despite the shortcomings, the film is widely used to cover greenhouses and greenhouses. The technology of mounting the film is quite simple. The film can be mounted both on screws through strips, and on special clamps for pipes.
Types of fastening film to the frame
Note! When fixing the film on the screws, you can use an old PVC garden hose cut in half as a strip. He gently covers the pipe and does not tear the film.
Step 1. Sew up the ends of the greenhouse film. A piece of film is cut from a suitable width of the film according to the size of the end part with allowances of at least 20 cm on each side. The film is applied to the end wall, the allowances are brought on the wrong side and the film is fixed on the sides and at the top point with temporary fastening. To do this, you can use the tape - they grab the film stock from inside the greenhouse. Align the film, eliminating creases and folds. Fasten it around the entire circumference in increments of about 60 cm for temporary fixings.
Fixing the film on the ends
Step 2. Cover the greenhouse with a film with a margin of at least 30 cm below and at least 20 cm from the ends. Align the film, eliminate creases and folds. Fasten along the extreme arches to a permanent mount - clamps or screws through the bar. Mounting step - no more than 30 cm.
The greenhouse is covered with a film
Step 3. Bottom of the film is attached to the lower screeds or sprinkled with earth. On the intermediate arches the film is attached to the screws through a bar, a hose or rubber gaskets. Places of contact with the arcs can be strengthened with duct tape.
Fixing the film at the bottom of the greenhouse
Step 4. Cut out the openings under the door, leaving the allowances of at least 20 cm. These allowances bend inside the greenhouse around the doorway and fasten on racks in the chosen way. Sheathe film doors and vents.
Step 5. The free ends of the film are cut or glued to the tape. If left to hang freely, in windy weather, the film will begin to tear.
Cutting excess film and fixing it with tape
The homemade greenhouse is not at all inferior to industrial analogues in the ability to create a microclimate favorable for plants. Its price is several times lower. To make such a greenhouse with your own hands is not at all difficult if you follow the instructions given and the advice of the craftsmen.
