Galvanized Steel Coil Application
Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It's especally useful for countless outdoor and industrial applications.
They are mainly used in building roof, door, window, roller shutter doorand automobile's vehicle shell, chassis, door, trunk lid, Oil tank, and fender, and also electric equipments, such as refrigerator base and shell and so on.
