Hot Dipped Az150 G550 Gl 1mm Carbon Steel Galvanized Steel Coil
What is a galvanized steel coil?
Hot dipped galvanized steel sheet & coil is made of carbon steel coated in zinc utilizing the hot-dip process. The end result of this process is a layer of zinc on each side of the steel sheet or coil that is tightly adhered to the steel through the formation of an iron-zinc alloy bonding layer.
