Galvanized Steel Sheets

Product Details

Galvanized Steel Coil gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized steel Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, Galvanized steel Coil is an essential fabrication component.

Hot dip galvanized steel coil. A thin steel sheet with a layer of zinc adhered to its surface by immersing it in a molten zinc bath. At present, continuous galvanizing process is mainly used, that is, the rolled steel coil is continuously immersed in the bath with zinc melting to make galvanized steel coil.

The requirements of chemical composition of galvanized coil are different in different countries. The national standard is to detect the content of carbon, manganese, phosphorus, sulfur and silicon.
