Why should the greenhouse skeleton be made of hot-dip galvanized material?
Hot-dip galvanized materials are very common in the application of tunnel greenhouse frames, mainly because this treatment process can improve the durability and corrosion resistance of steel. The following are the main reasons why hot-dip galvanized materials are widely used:
1. Corrosion resistance: hot-dip galvanized steel pipe is to form a coating layer of zinc on the surface of the steel by dipping the steel material into the melted zinc. This zinc coating can form a strong protective barrier on the steel surface, effectively preventing corrosion factors such as water and oxygen from reacting with the steel.
2. Durability: The durability of hot-dip galvanized steel pipe can be greatly extended, especially in changeable outdoor weather conditions. Compared with the steel material treated by cold galvanizing (electric galvanizing), the zinc layer is thicker in hot galvanizing treatment, and the zinc layer is stronger in binding force with the steel, so the hot-dip galvanized steel pipe can last longer without corrosion under the same conditions.
3. Comprehensive protection: The hot-dip galvanizing process ensures that every corner of the material is covered with zinc, including sharp angles, sharp edges and hidden holes, which are most easily overlooked and where corrosion first begins.
4. Self-healing: The zinc layer has a certain self-healing ability. Even if the coating is damaged, zinc continues to protect the steel from corrosion by forming a corrosion-resistant oxide around the damage.
Economy: Although the initial cost of hot dip galvanizing may be higher than some other coatings, the overall life cost (including repair, replacement and maintenance costs) is usually relatively low due to its long-term durability.
6. Easy maintenance: Compared with steel that needs to be painted regularly, hot-dip galvanized steel hardly needs maintenance, which can save long-term maintenance costs and labor.
7. Environmental adaptability: The greenhouse is exposed to the outdoor environment all year round, and will be affected by natural conditions such as humidity, high temperature and ultraviolet radiation. Hot-dip galvanized materials can adapt to these conditions and maintain the integrity and functionality of the structure.
8. Environmental protection:hot-dip galvanized steel pipe process is more environmentally friendly than other protection methods such as painting, which may use organic solvents during the painting process, which may cause environmental pollution after evaporation.
Therefore, hot-dip galvanized steel pipe is a very ideal choice in the construction of greenhouse, its good durability and corrosion resistance characteristics can ensure the stability and durability of the skeleton structure, extend the service life of the tunnel greenhouse, reduce maintenance costs, and improve the use of the tunnel greenhouse.
