Hot Dipped Galvanized Steel Coil
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 is especially useful for countless outdoor and industrial applications.
