Structure Galvanized Steel usually included two types. One is: cold rolled coil based plate, another one is Hot rolled coil based plate. Cold Rolled Hot-Dipped Galvanized Steel’s thickness range is usually from 0.4-2.0mm.Hot Rolled Hot-Dipped Galvanized Steel’s thickness range is from 1.8-5.0mm.

They are mainly used for Structure Budiling Construction,Solar Energy Equipment, Auto Parts, Household Appliances, Machinery etc. The Character of Structure Galvanized Steel is strong corrosion resistance, good surface quality, beneficial to deep processing. Hereby we list some main grade of it with Yield Strength (Y.S-MPA)/Tensile Strength(T.S-MPa)/Elongation(%).
