The greenhouse is made of a strong steel frame that can withstand snow and wind loads at the highest level. Such strength is possible thanks to modular arcs made of a steel profile measuring 20x20. Arcs are laid out with a step of 1 m. This design has passed all the tests on more than one summer cottage. In the basic version, the greenhouse has modular ends with doors and two windows. Number of horizontal jumpers (stringers) in the basic configuration — 5 pcs. Stringers are installed in a plane with arcs. It is covered with cellular polycarbonate. Honeycomb polycarbonate has a number of useful properties that are so necessary for growing greenhouse plants, namely: 1. Stable temperature inside the greenhouse
greenhouse, which is ensured by the tight fit of polycarbonate to the structure of the greenhouse due to the correct geometry of the arcs. 2. Transparency for light rays of the visible spectrum (transmission of light is up to 86% in 4 mm thick polycarbonate.) 3. High resistance to mechanical effects and sharp shock loads. The features of polycarbonate greenhouses are: *easy to install;*firmly hold their shape even with high snow loads;*have special windows and doors that provide the necessary air circulation;*fully mobile and allow the construction to be moved to another place.
