Q235B Galvanized Steel Coil 

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 treatment can improve the corrosion resistance and wear resistance of the steel plate, and can also increase the aesthetics and service life of the steel plate.  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.
