What material does galvanized coil belong to

Galvanized coil belongs to plate material class. The plate category includes hot rolled, coil, cold rolled, galvanized, silicon steel, tin and other building materials including rebar, Angle slot, wire, H beam, rail and so on.

Galvanized coil is to prevent the surface of the steel plate from corrosion and prolong its service life. The surface of the steel plate is coated with a layer of metal zinc. The zinc coated thin steel plate is called galvanized plate. Galvanizing is an economical and effective preservative method that is often used.

Galvanized coil, dip a sheet steel plate into a melted zinc tank, so that the surface adhesion of a zinc sheet steel. At present, continuous galvanizing process is mainly used in the production, that is, the steel plate into a roll of continuous dip in the melting of zinc in the plating tank to make galvanized steel alloy galvanized steel plate.

This steel plate is also made by hot dipping, but immediately after it is out of the groove, it is heated to about 500℃ to create an alloy coating of zinc and iron. This galvanized coil has good coating tightness and weldability.
