While zinc is frequently the metal of choice to provide corrosion protection, a zinc-nickel alloy such as the one offered by Sharretts Plating Company tends to produce better long-term results than when coating with zinc alone. In fact, zinc-nickel is a top choice for corrosion protection in the automotive industry.

Hot Dip Galvanizing

Hot dip galvanizing protects steel from corrosion due to a metallurgical bond that occurs when steel is submerged in molten zinc. The reaction creates intermetallic layers, harder than the base steel itself, resulting in an extremely abrasion resistant coating that can last for decades.
