Manufacturers seeking metal finishing services typically prefer zinc plating because it provides effective, long-lasting results at a relatively low cost. Zinc plating acts as a sacrificial anode that forms a protective barrier to prevent oxidation from reaching the surface of the part. Zinc plating is used on both small and large parts; common small parts include fasteners, crank handles, springs and other hardware items. Large parts include frames and chassis.
Among the plating specifications we meet is ASTM B633. This specification lists four classes of zinc plating: Fe/Zn 5, Fe/Zn 8, Fe/Zn 12, and Fe/Zn 25. The number indicates the coating thickness in microns (µm).
