Galvanized steel coils is to prevent corrosion on the surface of the steel sheet and prolong its service life. The surface of the steel coil is coated with a layer of metal zinc. This kind of galvanized steel coil is called galvanized coil.
According to production and processing methods, galvized steel coil can be divided into “Hot-dip galvanized steel coils”, “Electro-galvanized steel coils”, “Single-sided and double-sided differential galvanized steel coil”, “color galvanized steel coil”, ects.
Hot-dip galvanized steel sheet coil. The thin steel plate is immersed in the molten zinc pool, so that a thin layer of zinc is adhered to the surface. At present, it is mainly produced by continuous galvanizing process, that is, continuous immersion of rolled steel sheets in a galvanized pool with molten zinc to make galvanized steel coils.
