On zinc castings, decorative finishes are achieved by wet painting, powder coating, chromating, phosphate coating, nickel plating, brass plating, tin plating and chrome plating.

Painting, chromating, anodizing and iridite coatings can be used as corrosion barriers. Hard chrome plating can be utilized to improve wear resistance and bright chrome plating is a prevailing choice for hardware applications.

On aluminum castings, Decorative finishes and improved corrosion resistance are achieved by wet painting, powder coating, iriditing, and anodizing. Hard coat anodizing on aluminum surfaces can greatly improve wear resistance
