Using all-steel frame material as the greenhouse structure, the main body of the greenhouse has a long service life, lasting up to 20 years or more. However, attention must be paid to rust and corrosion prevention of the greenhouse frame, with hot-dip galvanized steel frames generally used. The greenhouse frame has strong wind and snow load resistance. Based on the local natural environment, including wind, rain, snow, and other natural conditions, suitable frames and covering materials should be selected.

2. Generally, bolted greenhouse frames are used, which are convenient to install, cost-effective, and durable. If welding is used, the weld joints are prone to rust, which can significantly reduce the service life of the greenhouse frame. Therefore, when processing greenhouse frames, it is advisable to use drilled bolt connections as much as possible to avoid weld joints.

3. The indoor space is large, with high land utilization efficiency, making it suitable for large-scale planting and mechanized operations.
