Zinc electroplating is a method of depositing zinc metal on the surface of another metal, such as steel, by immersing the item in an appropriate plating bath and applying electrical current.
Zinc travels through the electrolytic bath from the zinc anodes and attaches to the surface of the part being coated. The thickness of zinc plating depends on the time spent in the plating bath, the amount of current, and the chemical composition of the bath.
Zinc electroplating provides corrosion resistance to the steel part by acting as a barrier and sacrificial coating. Zinc is more electrochemically reactive than steel, so when exposed to a corrosive environment, the zinc plating corrodes sacrificially, delaying rust formation on the steel part even after portions of bare steel are exposed.
Zinc plating applications are conveniently provided to MPG customers through our on-site affiliate Medina Plating Corporation - producing the highest quality of rack zinc, zinc iron and zinc nickel alloy plating.
