China Roofing Material Gi Zinc Coated China Hot Dipped Galvanized Steel Coil

Galvanized steel coil is traditional widely used in construction,funiture,home appliances,automobile industry and interior decoration.lt is also the basic steel for PPGI/PPGL steel coil.
The galvanized steel coil is a thin plate in which a thin steel plate is immersed in a molten zinc bath to adhere a layer of zinc to the surface.Galvanized steel is a surface treatment technique taht coats a layer of zinc on the surface of a metal,alloy or other material for aesthetics,rust prevention,and the like.The main method used is hot-dip galvaanizing.Zinc is easily soluble in acid and soluble in alkali,so it is called an amphoteric metal.Zinc hardly changes in dry air.In moist air,a dense zinc carbonate film is foemed on the zinc surface.In the atmosphere containing sulfur dioxide,hydrogen sulfide and marine,the corrosion resistance of zinc is poor, especially in the atmosphere containing high temperature and high humidity containing organic acid,the zinc coating is easily corroded.
The standard electrode potential of zinc is -0.76V.For steel substrates,zinc coating is an anodic coating,It is mainly used to prevent corrosion of steel.Its protective performance has a great relationship with the thickness of the coating.After passivation,dyeing or coating of the photoresist,the zinc coating can significantly improve its protecion and decortive properties.
