As galvanized steel coils, is the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plates is continuously immersed in a plating tank with zinc melted to make galvanized steel plates; alloyed galvanized steel sheet. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.
Zinc coating is divided into: normal spangle coating, small spangle coating, no spangle coating, zinc-iron alloy coating, differential thickness coating and skin pass.

Galvanized steel refers to that ordinary carbon construction steel is galvanized, which can effectively prevent corrosion and rust of steel, thereby prolonging the service life of steel. Among them, galvanizing is divided into electro-galvanizing and hot-dip galvanizing. Generally used in building exterior walls, such as glass curtain walls, marble curtain walls, aluminum curtain walls as columns and stress materials, or used in outdoor telecommunications towers, highways and other open-air construction steel called galvanized steel, of which galvanizing is divided into electro-galvanized and hot Dip galvanized.
