Product Introduction：
Galvanized steel coil & sheet 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. This bonding layer is formed by a diffusion process while the heated steel is in contact with molten zinc. Chesterfield can provide hot dipped galvanized steel sheet & coil to meet your ASTM requirements with customer-driven surface finish options.
Sino Sea Steel is a galvanized steel coil supplier that maintains a constant inventory of galvanized steel grades most commonly used by our customers. The strategic alliance established with domestic mills gives us access to additional grades as the need arises.
