Hot-dip galvanized surface treatment, which has better anti-corrosion performance.

The steel structure building adopts hot-dip galvanized surface treatment, which has better anti-corrosion performance. Hot-dip galvanizing is a process in which a metal, typically steel or iron, is coated with a layer of zinc to protect it from corrosion. This process involves immersing the metal in a bath of molten zinc at a temperature of around 450 degrees Celsius (840 degrees Fahrenheit).

During hot-dip galvanizing, the metal is cleaned to remove any dirt, rust, or other impurities. It is then dipped into the molten zinc, which adheres to the surface of the metal. The zinc coating provides a barrier that prevents moisture and corrosive elements from reaching the underlying metal, effectively protecting it from rust and corrosion.
