Galvanized steel sheet is a steel sheet whose surface has been galvanized, usually by immersing the steel sheet in molten zinc to form a layer of zinc on the surface. This kind of steel plate is also made by hot dip method, but it is heated to about 500 ℃ immediately after coming out of the groove to form an alloy coating of zinc and iron. 

The advantages of galvanized steel sheets include corrosion resistance, wear resistance, high temperature resistance, easy processing and maintenance, etc. The disadvantage of galvanized steel is that the zinc layer will corrode gradually, so it needs to be maintained and replaced regularly.Galvanized steel sheets are widely used in construction, manufacturing, automobile industry and other fields.
