Zinc Electroplating is one of the most common forms of electroplating and popular because of its relatively low cost, protective nature and attractive appearance. The coating done through this process gives corrosion protection to ferrous components and it can give colors like gold, black or olive drab finish, by post treatment. 

The zinc electroplating process can be used to coat nuts, bolts, washers and automotive parts, such as interior components and gas filters. It also provides an effective undercoat for paints, when high corrosion performance is required. The most widely used zinc plating solutions are acid chloride, alkaline non cyanide, and cyanide, and the most widely used zinc alloys for electroplating are zinc-nickel, zinc-cobalt, and zinc-iron.

Any metal can be plated through the zinc electroplating process, but the most common are steel and iron, on which the process offers sacrificial protection.
