The choice of arch materials for vegetable greenhouse construction is relatively fixed. There are two common types, one is bamboo pole and wood as the main material, and the other is hot-dip galvanized thin-walled steel pipe as the main material.

         Greenhouses with bamboo poles and wood as arch materials are more common. The advantage is that the material is easy to obtain, the construction is convenient, and the cost is low. It only needs two to three thousand yuan per acre; but the disadvantages of cheap are the low strength of the arch, the poor resistance to wind and snow, and the wood and bamboo poles are easy to decay, so they need to be repaired and Replacement, operation management is not convenient.

         The other kind of greenhouse with hot-dip galvanized thin-walled steel pipe as the arch material appears to be slightly high-grade. Because the material used is relatively good, it has high strength, strong resistance to wind and snow, good rust resistance, high light transmittance, and convenient operation and management. However, it has been used for more than ten years and has a long life. Correspondingly, its cost is relatively high, and it requires a large amount of investment at one time, which is suitable for long-term greenhouse customers.
