5000 sqm Multi-Span Plastic-Film Greenhouse for Tomatoes
The multi-span film greenhouse does one thing well: it cuts the cost per square meter of a controlled growing environment without sacrificing the basics that matter. PO film on the roof and sides gives you enough light for strong crop growth, decent heat retention at night, and it holds up better over time than standard polyethylene. We've shipped these to farms growing everything from leafy greens to strawberries to potted flowers — it's the workhorse choice when ROI is the priority.
Product Description
A film greenhouse keeps things simple — galvanized light steel frame, arched profile, high-strength anti-aging agricultural film pulled over the top. The arch handles snow and wind on its own, no extra engineering needed. Single layer, double layer, or insect net only — pick what fits your climate and your crop. The film we use is from a newer domestic formulation that lasts two to four years longer than the standard stuff on the market. Vegetables, fruit, seedlings, hydroponics — people run all kinds of things under these. Heating and cooling swap in or out depending on where you are. We handle design, installation, delivery, and anything that comes up after.

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/㎡.
