The frame is considered one of the most important elements of the greenhouse, the strength and durability of the structure depends on the material. Greenhouses made of polypropylene or PVC pipes They have recently become more and more common, which is largely due to the large number of material advantages and affordable cost.
There are a large number of types of designs, greenhouses can be of various sizes, are made in the shape of a rectangle or arch. As a covering the film or sheets of polycarbonate is most often used.
Specifications
Polypropylene pipes with a diameter of 20 mm are usually used for the construction of the frame. The material is characterized by high ductility, excellent bends, creases in the construction process are not formed. The choice of the size of the greenhouse depends on the needs of the gardener, the standard length of the structure is 4, 6 and 8 m. For other framework options read here.
What is grown in them?
Greenhouses are very popular in harsh climatic conditions, as they allow you to get the first harvest in early spring. In the greenhouse of the water pipes can be grown almost everything. Most often in greenhouse conditions grown tomatoes, cucumbers, radishes and natural greens.
Advantages and disadvantages
The advantages of the frame made of polypropylene:
Other benefits:
strength - the design perfectly withstands wind and snow loads;- flexibility - due to this property, the process of erecting arched greenhouses is simplified;
- ease - the frame is easily installed and dismantled, if necessary, it is very easy to move it to another place;
- environmental Safety - the material does not release toxins hazardous to human and animal health;
- fire resistance - polypropylene is not subject to fire.
strength - the design perfectly withstands wind and snow loads;Disadvantages:
Despite the increasingly widespread use of polypropylene in the construction of greenhouses, there are also disadvantages:
- relative fragility in comparison with some analogs, for example metal pipes;
- the possibility of deformation from the wind and a small ability to withstand loads, in the form of snow.

Choice of covering material
The following materials are used in the construction of greenhouses:
- polyethylene film (reinforced, air-puffy, light-stabilized);
- agrofibre;
- polycarbonate;
- glass;
- agrofabric.
Today, the film is considered the most common material; it perfectly passes the sun's rays, is resistant to frost, and reliably protects plants from adverse weather conditions.
Glass as a covering material is not recommended, as the design can not withstand the weight of the material.

How to make a greenhouse stronger
Polypropylene long pipes built into the base without additional connections can collapse under the influence of wind.
To reinforce the greenhouse will help plastic pipes of large diameter, wooden boards or beams, metal pipes. All these components are installed in the center of the frame, immersed in the ground, which increases its resistance to adverse external conditions.
Each can build a greenhouse of polypropylene, the process will take no more than two or three days. This will require minimal skills and low financial costs. Such greenhouses are easy to use, they are reliable, lightweight and durable. If necessary, the greenhouse can be dismantled, install additional lighting and heating in it, equip the irrigation system.
