It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously dipped in the galvanizing tank with molten zinc to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel panel is also made by hot dip method, but it is heated to about 500℃ immediately after coming out of the tank, so that it can form an alloy film of zinc and iron. This galvanized coil has good paint adhesion and weldability.

Advantages

The main advantage of galvanized coil is that the surface oxidation resistance is strong, which can strengthen the corrosion resistance of parts. In addition, the surface of galvanized roll is clean and beautiful, which enhances the decorative material. Therefore, galvanized products are becoming more and more indispensable materials in manufacturing industry.
