How to make a greenhouse with your own hands from a profile pipe
The construction can be divided into several stages: 
- Choice of construction site.
- Foundation preparation.
- Frame installation.
- Sheathing with covering material.
- Construction sealing.
Preferably prepare in advance drawings of greenhouses from a profile pipe with dimensions.
Choice of construction site
To begin with, it follows, on which we will build our greenhouse. It should be flat, without tall trees, if possible - not far from the house (in the case of winter operation, it will be easier to carry out by connecting to the heating source of the house).
Foundation preparation
On which we are going to build a greenhouse, there can be 3 types:
- Lumber. It is made of a wooden beam with an external treatment to prevent corrosion. The service life of this type of foundation is up to 10 years.
- Brick. The use of this type of foundation becomes rational in cases where the installation of a greenhouse has to be done on a site with a natural slope. Service life - up to 30 years. It is carried out by performing brick-width masonry on a finely dispersed mortar, mixed in a ratio of 1: 3 (cement - sand).
- Concrete. This type of foundation is the most durable, but its construction is the most labor intensive. For its construction, it is necessary to dig a trench, with a depth and width of one bayonet of a shovel. Then, either equip it with a frame welded from reinforcement - in this case, the service life of the foundation becomes from 50 years, or simply pour it with concrete (up to 60 years). Concrete should be mixed in a ratio of 1:4:3.5 (cement, sand, small pebbles or broken stone).
The choice should be made based on considerations of durability, cost, as well as the conditions in which the construction of the structure is carried out.
Frame installation
Installation can be performed from various elements of rolled metal, but the most practical of them is a profile pipe.
It is a metal pipe with a rectangular cross section. Nowadays, a profile pipe is one of the most common elements of rolled metal products.
It is classified according to the length of the sides. Most often used for the production of frame structures, due to such features:
- the load is evenly distributed over the edges a rectangle, the shape of which has a profile section, which provides increased strength of the finished frame;
- affordable price per meter profile pipe makes the use of this material the most beneficial for the installation of frame structures;
- rectangular section shape simplifies the sheathing procedure cellular polycarbonate;
- the use of a profile pipe guarantees structural durability.
Profiles with sides of 40x20 and 20x20 are considered the best types of profile pipes for mounting a greenhouse frame, the difference between which is the calculation of the specific load per unit surface area.
Also, the choice of the profile used depends on the type of greenhouse from the profile pipe that we are going to build. They are lancet or pyramidal.

Do-it-yourself greenhouses from a profile pipe
Arched
Greenhouses with a vault in the form of a semicircle. Installation of this type of frame is associated with the need for uniform bending of the profile. This design is preferable for the budget production of a greenhouse, it contributes to the dispersion of sunlight and reduces the likelihood of snow accumulation during operation in winter.
For the installation of an arched greenhouse, it is worth using a 40x20 profile for supporting frames, 20x20 for longitudinal jumpers.
Bearing frames are made by bending a profile pipe. Here comes the question how to bend a profile pipe for a greenhouse. Bending can be done either manually or with a pipe bender.
Consider the option of manual production of load-bearing frames.
A pair of plugs are cut out of wood or plastic, with which the end of the pipe is plugged. Sand is poured inside, compacted as the pipe is filled. This is done so that, when bending, the load on the inner surface is distributed evenly.
The middle of the profile is marked, then it is fixed on a concrete ring with a diameter of 3 m. Bending is performed simultaneously in both directions, at an angle of 90 degrees to the fixation point.
TIP #1: For uniform bending, the bending point can be heated with a burner or blowtorch. This minimizes the risk of breaking or sharp bending.
TIP #2: In the case of greenhouse installation in the winter season, water can be used instead of sand. It should be poured into the profile and let it freeze. ATTENTION: This method requires increased care, freezing should not be allowed, otherwise the profile may break from the inside.
In addition, there is an option for bending a profile pipe using manual profile benders. A home-made machine, of course, will be inferior in presentability to factory ones, but it will be able to perform its direct functions just as well.
To create a profile bender at home with your own hands, you will need:
- Corner or channel, from which the frame is welded, on which the machine structure will be located.
- Legs from a pipe or a metal profile.
- Bending shafts (you can order them from a turner or at a metal warehouse).
- Transmission chain mechanism. If possible, you can use the transmission gears from the VAZ 21-06 timing mechanism.
- Tensioner (from there).
- Shaft guide. It can be made by welding two 20 mm corners together.
- The driving element of the guide. It is made from a profile pipe 40x20 mm.
- Adjustable screw.
- The handle is from improvised material.
- Fasten the main shafts with bolts, having previously made slots for them in the channel.
Lancet
Greenhouses of the form "house". They can be single or double. Mounting Requires welding skills.
Installation of greenhouses of this type is carried out by fastening individual parts of the profile pipe with “tacks”, so that the jumpers form windows 40x60 cm, 60x60 or 80x60, depending on the type of cladding used (the narrower, the heavier).
Use of the lancet frame type ensures that direct sunlight enters the greenhouse, plus makes it possible to equip the walls with reflectors. It is recommended for greenhouses in which it is planned to grow especially photophilous crops.
Pyramidal
The pyramidal frame of the greenhouse from a profile pipe is more rational for the construction, or buzfundamental folding,. In fact, this is a “cap” that covers a certain area of soil in order to form a microclimate under it.
Sheathing with covering material
For sheathing the finished frame, the following materials can be used:
- glass;
- sheets of cellular polycarbonate.
The use of polyethylene film is the least durable plating option. It will have to be changed every year.
- Pretty good plating. It provides an excellent level of light transmission, as well as tightness of the structure, with proper processing of the joints. Among the negative characteristics of glass as a covering material for greenhouses is its weight and fragility.
– modern synthetic material, the most rational for using it as a sheathing for a greenhouse. And drawings of greenhouses from a profile pipe can be easily found on the Internet.
This is due to the following features:
- The combination of "strength-lightness" allows, if necessary, to do without the construction of a capital foundation.
- . For this type of material, it is about 90% - this is more than enough for the normal growth of greenhouse crops.
- Thermal insulation - the honeycomb structure of polycarbonate implies the formation of an air gap.
Consider the process of sheathing the finished frame with sheets of cellular polycarbonate:
- depending on the type of greenhouse being mounted, it is marked out, then a polycarbonate sheet is cut, for reasons of maintaining the most complete plane;
- at the places of contact of the sheet with the metal frame, we install rubber pads, we also forgive the place where the sheets meet - this will facilitate further sealing;
- the sheet is sewn to the frame with self-tapping screws, with the obligatory use of thermal washers. Holes for self-tapping screws are drilled in advance, 1-2 mm larger than their diameter - this will prevent cracking of the sheet structure during thermal expansion;
- sheathing should be made at the rate of 30 self-tapping screws per six-meter polycarbonate sheet. You should not sew up every place of contact with the frame - polycarbonate does not like a large number of holes;
- the polycarbonate sheet should be mounted with honeycombs down - this provides for the likelihood of accumulation of condensate in them;
- by sealing the holes of the honeycombs with a special tape, you can prevent the accumulation of dirt and insects in them.
IMPORTANT: For sheathing, it is worth using reinforced polycarbonate with UV protection. The side reinforced with a protective film must be oriented to the street.
Construction sealing
Sheet joints should be treated with silicone or sealant, in order to give the structure tightness, which is a necessary condition for the formation of a microclimate.
For the same purpose, the gap between the foundation and the sheathing sheets is treated with a finely porous structure foam.
ADVICE: A little trick that can help with heating in the winter is to put cow or horse manure under them before pouring the beds, then tamp down, cover with earth on top. Preya, it will give off some heat, which may be able to save the root system of your lovingly grown crop from sudden frosts.
As you can see, a greenhouse from a profile pipe 20 at home, with your own hands, is quite realistic. In addition, with the responsible implementation of the recommendations above, this does not require large expenditures of labor and finances.
Of course, the choice of the type of material is at the discretion of the master, but when using the materials specified in the recommendations, the price-quality ratio acquires the most acceptable parameter.
We hope you now know the answer to the questions how to make a greenhouse from a profile pipe whether it is necessary to order a greenhouse project from a profile pipe, what is the difference between a pipe greenhouse and other metal greenhouses.
