It is cold-rolled or hot-rolled, long and narrow long steel plate is coated with a layer of raw materials called (zinc, aluminum) to varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized strip steel matrix undergoes a complex physical and chemical reaction with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a compact structure. The alloy layer is integrated with the pure zinc layer and the strip steel matrix. Therefore, its corrosion resistance is strong.
