Hot-dip galvanized steel coil is coated in liquid zinc after cold rolling of the strip steel. The hot dip galvanizing coil has excellent formability, impact resistance, good corrosion resistance and good welding. The complex physical and chemical reactions of the substrate and the molten plating bath of the hot dip galvanized steel strip form the structure of the Zn-Fe alloy layer. The alloy layer is integrated with the pure zinc layer and the strip matrix, so it has a strong corrosion resistance. It can be achieved without the outside environment influence, always maintain itself best performance and appearance.
