To get a harvest of vegetables early or have a lot of flowers in the cool season, greenhouses are installed. Unlike greenhouses under the film, structures made of metal pillars and walls with a roof of polycarbonate sheets are able to withstand strong wind, hail and even a layer of snow. They do not need to be disassembled for the winter, but they can be planted in seedlings already in early spring, when the sun is not covered by clouds. But polycarbonate greenhouses come in different shapes, with their own design features and sizes. After reading this article, it will become clear what models of greenhouses are in form and materials, and what to look for when choosing this structure.

Polycarbonate greenhouse which company choose
Production of greenhouses includes welding and metalwork, which should be carried out in workshops equipped for this. A number of companies specializing in the manufacture of facilities for year-round use in a warm climate or seasonal use, without disassembly, for the winter, have such production areas.
Among the leading companies in the industry are:
1. "Will"
2. TD "Harvest"
3. HRT "Basis"
4. Glass house
5. "Novoladozhsky plant"
Volia has its production base in the city of Dubna, which is not far from the capital of Russia. The company's engineers calculated numerous models of greenhouses and greenhouses for large and small farms. The range of companies canopies and other household equipment, which is adapted to the Russian climate. The company not only sells, but also installs metal structures throughout the country. To do this, there are offices in St. Peretburg, Ufa, Nizhny Novgorod, Samara and Yekaterinburg.
Glass House has been operating since 2001 and has the slogan “Transparent Solutions”. Many models are designed in an original way and have no analogues in other companies. Metal elements are carefully processed so that the garden structure can serve up to 30 years.
TD “Harvest” has been producing its products since 2004 and has more than 200 dealers in Russia and adjacent countries. Their feature is the introduction of personal preferences of the customer in the drawing of the greenhouse, in order to adapt it to the needs of a specific user.
Top arched polycarbonate greenhouses
Fully arched structures, from the ground itself, are very practical in harsh conditions when there is a lot of rainfall in winter. From the roof without sharp corners, the snow moves easily under its own weight, which facilitates the maintenance of the structure, and the spherical shape has great aerodynamic properties and better resists strong winds. Polycarbonate, due to its flexibility, easily adapts to such lines of metal construction. Among the best greenhouses of this form, according to user feedback, are the following models.
