According to the production and processing methods can be divided into the following categories:
1. Hot dip galvanized steel panel. Immersing the steel panel in a molten zinc bath to make the surface of the steel panel adhere with a layer of zinc. At present, the continuous galvanizing process is mainly used, that is, the rolled steel panel is continuously immersed in a plating bath melted with zinc to make galvanized steel panel.
2. Alloyed galvanized steel panel. This kind of steel panel is also made by hot dip method, but it is heated to about 500β immediately after coming out of the tank, so that it can form an alloy film of zinc and iron. This galvanized panel has good adhesion and weldability of... less
