Commercial Polycarbonate Sheet Nursery Greenhouse With Shading Net System

Product Description

Plastic shed is a single span arch roof shed without heating, which is covered with plastic film. The plastic greenhouse has the advantages of simple structure, convenient use and less investment. They are a simple conservation tillage facility. With the development of plastic industry, it has been widely used in the world. Generally, plastic greenhouse does not heat indoors, but stores heat by greenhouse effect. The lowest temperature is generally 1-2 ℃ higher than that outside the room, and the average temperature is above 3-10 ℃. The transmittance of plastic greenhouse is generally 60% - 75%. In order to ensure the basic balance of the average light throughout the day, the layout of greenhouse mostly takes the form of extending from north to south.

Professional design

The basic requirements for the use of circular arch shed are 8 meters wide, 30 meters long, 1.8 meters shoulder height and 3 meters top height. 04M or more. The material is hot-dip galvanized steel. Three longitudinal tie bars are designed to enhance the wind resistance and compression resistance. Four longitudinal film pressing grooves (two grooves on each side) were designed. The skirt film is 40cm high, with a film pressing groove fixed on the upper side and buried in the soil on the lower side to enhance wind resistance and sealing. The second one is installed at 140cm above the ground, and the roll film and skirt film repeat 30cm. At the end, there are 6 upright poles, each raft is provided with membrane rope between two arches to increase wind resistance, and four corners are provided with wind bracing to increase the stability of shed door. The door size is 1.8 × 1.4m, and each raft has 2 columns in total.
