For galvanized steel coils, the steel sheet 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 plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. 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.

Galvanized iron sheets are widely used for construction, building, roof sheets, automobiles, agriculture,home appliances, vanitation pipe and commercial industries.
With the technological innovation and product development of the galvanizedsheet industry, While the traditional galvanized sheet market continues to maintain steady growth, new products, new processes, and new technologies for galvanized sheet continue to emerge, differentiated and functional galvanized coil products continue to be developed, and the application areas continue to expand. In the future, galvanized sheets may be widely used in new energyvehicles, high-end equipment manufacturing, aerospace and other industries, becoming an important driving force for the development of the industry.

According to the processing method, we divide galvanized steel into the following categories:
1. Hot-dip Galvanized Iron Sheet
As the name implies, hot-dip galvanizing is immersing the cleaned iron sheet into the molten zinc bath at about 500 degrees to form a zinc layer. It is the most commonly used method. It has some advantageous features:
1) The entire steel surface is uniformly covered with a zinc layer, even the corners, hollows, etc. so that the steel sheet is fully protected. 2) The cost of hot-dip galvanizing is cheap.
2. Electro-galvanized Iron Sheet
Electro-galvanizing is a process of applying a layer of zinc to steel through electroplating, with a saline anode and steel conductor. It is able to enhance the corrosion and heat resistance of steel. Also, it makes steel sheets more good-looking.
