Two arch materials for vegetable greenhouse construction

　The selection of arch materials for vegetable greenhouse construction is relatively fixed, and there are two common types: one is based on bamboo and wood, and the other is based on hot-dip galvanized thin-walled steel pipe.

Greenhouses with bamboo poles and wood as arch materials are more common. The advantages are easy to obtain materials, convenient construction and low cost. It only needs two or three thousand yuan per mu; However, the disadvantage of low cost is that the arch frame has low strength, poor wind and snow resistance, and the wood and bamboo rods are easy to decay, so they need to be repaired and replaced every year, which is not convenient for operation and management.

The other kind of shed with hot-dip galvanized thin-walled steel pipe as arch material is slightly high-grade. Due to the excellent materials used, it has high strength, strong wind and snow resistance, good anti-corrosion performance, high light transmittance and convenient operation and management. However, it has been used continuously for more than ten years and has a long service life. Accordingly, its cost is relatively high and requires a large one-time investment. It is suitable for long-term greenhouse customers.
