Column-free steel skeleton of Greenhouse

Greenhouse frame Features: 1, can be any multi-span, with high ceilings, large spaces, wide field of vision, saving land, to facilitate mechanization and so on. 2, the frame column using 100x 50x 2.5 galvanized rectangular steel tube, high structural strength. Greenhouse function and can be equipped with equipment: 1, natural ventilation, the top of the sunroof open, help rid the indoor hot air, and with the composition of the side shutter good ventilation system, electric sunroof structure, use either manually ventilated area up to 20%. 2, forced ventilation, end with a low pressure high flow fan, summer cooling, humidity and good effect. 3, interior shading. Insulation curtain (aluminum foil net) electric control. 4, Outdoor Shade net (black shade nets) electric control. 5. Growth frame, mesh structure can withstand crop load 15 kg / m. 6, surrounded by insect net, 25 mesh nylon braid. 7, Configuration Ejecta (the spray), irrigation (drinks) irrigation system. 8, the bottom of the gutter configuration plot exposed sink, collecting dew condensation can reduce the humidity, the domestic plastic greenhouse initiative. 9, winter insulation can set the buffer doors. 10, a large section of the trapezoidal gutter, high strength, smooth drainage, adapted to the maximum rainfall of 148mm / day.
