Large Height 3-10m Polytunnel Greenhouse The Ideal Growing Environment for Your Crops

1. Framework
The primary beam adopted fully hot-galvanizing pipes, joined by hot-galvanizing profile or fixed by hot-galvanizing steel wire, good monolithic resistance to corrosion, strong and durable.
Advantage of the hot galvanizing frame:
A---Long service life because of the resistance to corrosion of the humectate condition. The frame can be made of U-steel, C-stell, Circular pipe and Oval pipes.
B---Large operation space becuase of the structure without inner columns. The beams of the frame is made by the technology of forming in one time.
C---And the beams made of hot galvanizing steel pipe, U-steel or oval pipe can be designed as double arches beams for the double film to preserve heat in the cold winter.
D---The hot galvanizing frame is strong enough to support the other necessary devices to be assembled in the greenhouse, the air condition for example.

2. Coverning material
The covering material of PEP for the mushroom greenhouse.
The PEP film is composed of 3 layers.

B---The middle layer is EVA for the insulation
C---The third layer is PE for inner space. It is anti aging and auxiliary treated of anti-drip.

3. Shading system

The shading system can keep the greenhouse temperature down.

4. Ventilation system

Motor driven or manual rolling vents on two sides

1. All the steel material is nude packing.
2. Motor and electric machines are put in carton.
3. Small steel parts are put in bag.
4. Glass is put in iron frame.
5. All the material is put in containers.
