Galvanized (Aluminum) Zinc Sheet

Galvanized Steel Coil is a zinc-coated steel sheet, mainly processing alkali and degreasing, acid bath, flux bath, anneal treatment, molten zinc dip, spangle-making, chromate treatment, oiling and other stages.

● Hot dip galvanized steel to prevent corrosion of steel surfaces subjected to extend its service life, in a layer of metal zinc coated steel surface, so that it improved the surface characteristics of thin steel plate.

● Hot-dip galvanizing is cold rolled strip steel by the formation, after annealing into the continuous hot galvanizing line, through a series of processes, surface hot-dip galvanized to form. Galvanized steel plate was good at corrosion resistance and high strength, easy processing and so on.

	Different Thickness Coating A (g/m ² ) / B (g/m ² )(A≠B)
By negotiation between supplier and buyer, the code for equal thickness coating can be represented by the sum of both weights, where A is the coating weight on the outer surface of the steel strip or steel plate (g/m ² ); B is the coating weight on the inner surface of the steel strip or the underside of the steel plate (g/m ² ).
