Sainpoly's intelligent Multi-span film greenhouse for agricultural product cultivation
Product Description
Plastic film spans multiple greenhouses, saving costs and being easy to use. It adopts a combination of hot-dip galvanized light steel structure and high-strength anti-aging agricultural film, with an arched streamlined design. The overall structure is relatively simple and has strong resistance to snow and wind. For different situations, single-layer film, double-layer film or pure insect proof net composite structure can be used. Our film adopts new domestic technology, and the service life can be extended by 2-4 years compared to normal. This product is widely used in various planting scenarios, such as vegetable planting, fruit planting, and seedling hydroponics. The heating or cooling system can be replaced and adapted in different environments. We support one-stop service from design, installation, delivery to after-sales service.

Application and Solutions
In winter, when the temperature drops below -30 ℃, vegetables freeze to death. The double-layer inflatable film, insulation system, and heating interface are used, with a double-layer film structure and an air insulation layer formed in the middle. The insulation rate can be increased by more than 30%
Risk of Snow Collapse
Reinforced truss+steep roof design, enlarged main skeleton section, nodes connected by high-strength bolts, roof designed as a steep arch or apex, snow load design value can reach 0.8-1.0kN/㎡.
