Description	Galvanized steel is mild steel with a coating of zinc. The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel. Zinc steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion

Hot dip galvanizing: the molten metal reacts with the iron matrix to produce an alloy layer, so as to combine the matrix and the coating. Cold galvanizing: the amount of galvanizing is very small, only 10-50g / m2, and its corrosion resistance is much different from that of hot-dip galvanized pipe.

Galvanized coil

For galvanized coils, the sheet steel 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 ºC to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.
