Steel Coil Color Coated Galvanized Steel Coil Iron Coil

The galvanized steel sheet is to prevent the surface corrosion of the steel sheet to prolong its service life, and a layer of metal zinc is coated on the surface of the steel sheet, and the galvanized steel sheet is called a galvanized sheet.

According to the production and processing method can be divided into

(1) Hot-dip galvanized steel sheet. The sheet is placed in a bath of molten zinc to adhere a layer of zinc flakes to its surface. At present, the continuous galvanizing process is mainly used, that is, the galvanized steel sheet is continuously rolled in the melt galvanizing tank;

(2) Alloying of galvanized steel. This kind of steel panel is made by hot dip method, but after slotting, it is heated to a temperature of about 500℃ immediately to form a zinc-iron alloy film. This galvanized sheet has good coating and weldability;
