Galvanized coil: a thin steel sheet that immerses the steel sheet into the molten zinc bath to make its surface adhere with a layer of zinc. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate; Alloyed galvanized steel sheet. This kind of steel plate is also made by hot dip method, but it is heated to about 500 ºC immediately after coming out of the groove to form an alloy coating of zinc and iron. The galvanized coil has good coating adhesion and weldability.
Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides. There are two main processes used to produce galvanized steel: continuous hot dipping and electro-galvanizing.
The hot dipping process consists of passing the steel through a bath of molten zinc, while the electro-galvanizing process consists of the application of zinc through electrolytic disposition. The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer. Our hot dipped galvanized products are manufactured to ASTM A653 specifications; our electro galvanized products conform to ASTM A879 specifications.
