Zinc is chemically active, and then in the air at room temperature, the surface generates a thin and dense film of alkaline zinc carbonate, which can prevent further oxidation. Surface Properties: The surface of zinc sheet is smooth and free from burrs and cracks, shrinkage holes, laps and scales as well as necking, welding and crimping defects. Zinc sheet use: Widely used in steel structure surface, container, bridge, derrick storage tanks, power pylons, towers, capacitors, metal brackets, ductile iron pipe, traffic equipment and other surface zinc spraying , electroplating and other industries.
