DX51D/DX52D/DX53D Galvanized Steel Coil

For carbon galvanized steel coils, the zinc sheet is dipped into molten zinc sheet to adhere the zinc sheet layer to the surface. Galvanized seamless steel coils are mainly produced by the continuous galvanizing process, that is, the rolled steel plates are continuously immersed in the molten zinc in the galvanizing tank to make galvanized steel plates and alloy galvanized steel plates. This kind of coil is also made by hot dip, but it is heated to about 500°C immediately after being discharged from the tank to form an alloy film of zinc and iron. This galvanized steel coil has good paint adhesion and weldability. Similar product categories: color-coated steel coils, stainless steel coils, galvanized steel coils.

Galvanized steel coils are coated with zinc because rust will not attack this protective metal. The outermost layer is all zinc, but successive layers are a mixture of zinc and iron, and the interior is pure steel. These multiple layers are responsible for the metal’s amazing properties of withstanding corrosive environments. Zinc also protects steel by acting as a "sacrificial layer." If the surface of galvanized steel coils rusts, the zinc will be corroded first. This allows the zinc to be spread over the chip or scratch to prevent rust from reaching the steel. Galvanized steel oil is an essential manufacturing component for countless outdoor, marine or industrial applications.

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