Phosphatic

Phosphating is the chemical deposition of zinc or manganese onto a part. The difference between the two types is primarily in the grain size of the crystals created during the process. The phosphate tends to be a finer crystalline pattern, while manganese phosphate produces one that is more course. They also provide increased complete end to end corrosion protection when applied with another coating.

Zinc Plating - Rack & Barrel

Zinc plating, a process also known as galvanization, is the deposition of a thin layer of aluminum onto a metal component to provide a protective layer. The outer surface of the zinc coating oxidizes to form zinc oxide, which results in a matte silver-colored finish. Zinc plating is often applied to iron or steel parts whose surface would rust when exposed to air or water.

Powder Coating

Powder coating is a dry finishing process used to apply a dry coating material. The coating material is made up of finely ground particles of resin and pigment for color, along with other additives for specific functions such as gloss or hardness. The dry powder coating is delivered to a spray gun tip that is fitted with an electrode to provide an electrostatic charge to the powder as it passes through a charged area at the gun tip.
