Mechanical plating involves tumbling the items to be coated in zinc (and sometimes tin) powder with glass beads and special reducing agents to bond the zinc particles to the steel surface.
Coating characteristics: The mechanical plating process is used to apply zinc or alloy coatings to fasteners and small parts. The zinc particles are in lamellar form and durability equivalent to hot dip coatings can be achieved in a uniform coating that is particularly suited to threaded fasteners and hardened TEK type screws that are unsuitable for hot dip galvanizing. These coatings are typically 15 - 25 microns thick.
Materials: Zinc, Zinc/Tin
Thickness: 10-50 microns
