Applied on steel, Zinc plating is a soft, corrosion-resistant finish; decorative, ductile, marginally solderable and often used as a paint primer. Zinc is a sacrificial finish in that it will corrode before the base metal. Corrosion resistance is a function of thickness and can be enhanced by adding a conversion coating.  Suitable for providing shelf life for parts and in less severe environmental applications.
