Greenhouse framework adopts the hot dip galvanizing profile. All processing components adopt the process of welding before galvanizing, and its quality could be guaranteed for 20 years. The attached quantity of zinc is 490g/m2, and the thickness is more than 70 μm. All components are assembled at site, and the connecting pieces and fasteners don't corrode for 20 years. 

Cover materials are divided into solar panel, single-glass, hollow glass and so on. These are sealed with aluminum alloy sections and rubber strip for installation, which can ensure that the greenhouse has good air tightness. The aluminum alloy sections have the special passivation, and own better corrosion resistance than general aluminum alloy. 

Thin film; Po film, PEP film, etc., 8-15 silk has the quality guarantee for 3-5 years. 

Solar panel: It is ultraviolet-proof outside, has anti-condensation inside, good light transmission, good heat preservation and heat insulation performance, several levels of strength, rigidity, hardness, toughness, fracture resistance performance, quality guarantee of 10 years 

Single glass: It has beautiful appearance, excellent light transmission, and quality assurance for 10 years, while the thermal insulation property isn't as good as hollow sheet. 

Hollow glass: It has beautiful appearance, excellent light transmission, and quality assurance for 10 years, and the thermal insulation property is as good as hollow sheet.
