Zinc plating is a common finishing process which prevents the formation of rust. It is a cost-effective and straightforward way to ensure that components are protected from corrosion. In addition, zinc plating also enhances the appearance of parts, making them brighter and shinier.
Firstly, the components are thoroughly cleaned to ensure adhesion of the coating. Then, in the case of hot dip galvanising (a common form of zinc plating) they are placed in a bath of molten zinc before being removed and allowed to dry. This ensures that the components are thoroughly coated, with the resulting zinc layer acting as an effective barrier that preserves the structural integrity of the part.
