Film Multi-Span Greenhouse Material Composition:
 
Main frame is made of galvanized steel tubes, top and all around is covered by single-layer or double-layer PO film.
 
Film Multi-Span Greenhouse Characteristics:
 
1 Double-frame double-layer film greenhouse:
 
Double-frame double-layer film greenhouse use double-layer galvanized steel frame both on top and all around, and both inside and outside frame will be covered PO film, it has good heat insulation performance, can effectively save the heating energy consumption, suitable for being used in winter. Rolling film windows will be installed on both top and all around, good ventilation. This type can be used for planting crops.
 
Greenhouse specifications:P.S.: size can be customized.
 
2 Single-frame double-layer film greenhouse:
 
Single-frame double-layer inflated film greenhouse use single-layer galvanized steel frame both on top and all around, and the top will be covered by double -layer PO film. Double-layer inflated film greenhouse is a kind of energy-saving greenhouse, compared with the single-layer film greenhouse, it has significant thermal insulation effects (general energy saving more than 30%).Double-layer inflated film greenhouse, tension rope is not needed, only fixed around the film, through air compressor machine to support the film, make the inner film tightly close to the greenhouse frame, then outside film will be isolated with the inside film, thus forming the air interlayer for good heat insulation effect. Both inside and outside the steel frame will be covered by film, good heat insulation performance, can effectively save heating energy consumption, suitable for being used in winter, rolling film windows can be installed both inside and out side all around, electric gear and rack will be used for opening the skylight to reach good ventilation.
 
Greenhouse specifications:P.S.: size can be customized.

3 Single-Layer film multi-span greenhouse
Single-layer film greenhouse use single-layer hot galvanized steel frame, it will be covered by single-layer PO film on top and all around. Heavy snow and wind load design, strong drainability, commonly used in spring, summer and autumn. The greenhouse can be assemble with rolling film windows, external sunshade and cooling system.
 
Greenhouse specifications:P.S.: size can be customized.
