Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface. Galvanizing is an economical and effective method of rust prevention that is often used. Galvanized steel panels are coated with a layer of metallic zinc on the surface to prevent corrosion on the surface of the steel panels and extend their service life.

 

（一）definition

 

Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface.

Galvanizing is an economical and effective method of rust prevention that is often used.

Galvanized steel panels are coated with a layer of metallic zinc on the surface to prevent corrosion on the surface of the steel panels and extend their service life. This zinc-coated steel panel is called a galvanized panel.

 

 

（二）classification

 

Can be divided into the following categories according to production and processing methods

①Hot-dip galvanized steel plate. A thin steel plate is immersed in a molten zinc bath so that a layer of zinc adheres to its surface. It is mainly produced by the continuous galvanizing process, that is, the rolled steel plates are continuously immersed in a plating bath containing molten zinc to make galvanized steel plates;

②Alloyed galvanized steel sheet. This kind of steel plate is also made by the hot dip method, but it is heated to about 500°C immediately after coming out of the tank to form an alloy film of zinc and iron. This kind of galvanized sheet has good paint adhesion and weld-ability;

③Electro-galvanized steel plate. This kind of galvanized steel sheet manufactured by electroplating method has good process-ability. However, the coating is thin and its corrosion resistance is not as good as that of hot-dip galvanized sheets;

④ Single-sided galvanized steel plate and double-sided galvanized steel plate. Single-sided galvanized steel sheet is a product that is galvanized on only one side. In terms of welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized sheets. In order to overcome the shortcomings of one side not being coated with zinc, there is another type of galvanized sheet that is coated with a thin layer of zinc on the other side, that is, double-sided galvanized sheet;

 

 

（三）Usage

In the construction industry, it is used in light steel keels, building panels, corrugated boards, rolling shutter doors, etc. in various industrial and civil buildings; in home appliances and light industry, it is used in the shells and base plates of various household appliances.

Galvanized steel sheets are widely used in light industry, home appliances, automobiles and construction industries
