A large span plastic greenhouse is a greenhouse structure that uses plastic film as a covering material and has a large span. Usually, the span of a large span greenhouse is 8 meters and can be connected. With its spacious interior space, good light transmittance and heat preservation performance, double layer polyethylene greenhouse has become a very popular greenhouse form in modern agriculture. Big plastic greenhouse is suitable for large-scale cultivation of vegetables, fruits, flowers and other crops.
Large span plastic greenhouse composition:
Greenhouse frame:
Clear plastic polytunnel frame is made of hot-dip galvanized steel frame, which will not rust for 25 years in a high humidity environment. The project uses square tubes, U-shaped steel, C-shaped steel and other iron plates. Except for stainless steel products, all surfaces are treated with rust-proof hot-dip galvanizing, with a single-sided surface of more than 350g/m'.
Covering material
Clear plastic polytunnel covering material is made of HDPE/HDPO film, high light transmittance, anti-drip, anti-ultraviolet treatment, 150 micron thickness, different colors.
Climate Control Systems
Clear plastic polytunnel internal and external shading systems , fan and water curtain automatic cooling system, internal insulation system, heating system, control system, movable seedbed, irrigation system, etc. can be equipped according to customer requirements .

Large span plastic greenhouse characteristics:
The clear poly sheeting greenhouse has large space and high flexibility:
The biggest feature of the large span clear poly sheeting greenhouse is the spacious interior space.
The clear poly sheeting greenhouse has good light transmittance:
The clear poly sheeting greenhouse covering material is a highly light-transmitting film that can maximize the introduction of natural light and promote plant photosynthesis.
Building a plastic greenhouse is economical:
The construction cost of building a plastic greenhouse is relatively low, especially compared to a traditional glass greenhouse.
The clear poly sheeting greenhouse has better thermal insulation:
The film has good thermal insulation properties and can effectively maintain the temperature inside the large span clear poly sheeting greenhouse and reduce heat loss.
The clear poly sheeting greenhouse has good ventilation and humidity control:
The clear poly sheeting greenhouse is equipped with a comprehensive ventilation system, such as adjustable vents on the top and sides.
