About Zinc

Zinc is a bluish-white deposit which serves as an inexpensive decorative and sacrificial protective coating against atmospheric corrosion of iron and steel parts. It is commonly used on nuts, bolts, wire goods, fasteners, stampings and sheet metal parts. Zinc plating is generally further protected by the application of post-plate treatments such as chromates and sealers. These are applied to retard the beginning of zinc corrosion and, thus, the beginning of the basis metal corrosion.
