What is Zinc Electroplating?
Zinc electroplating is a soft, ductile, decorative, corrosion-resistant finish. Unlike most other commonly plated metals, zinc protects the substrate. The protection is accomplished by sacrificing itself. The zinc corrodes before the base metal thereby protecting the base metal. For additional corrosion protection, chromates are applied over the zinc. Chromates used in the zinc electroplating process become a component of the coating. Chromate films are typically very thin, and the chromate coating provides no measurable thickness to the overall coating. The Georgia Plating Zinc Electroplating Process Georgia Plating uses an acid chloride zinc plating process to provide our customers with zinc coated parts that meet the most stringent requirements. After the zinc plating process is complete, surface color of the finish provides insight into the level of corrosion resistance provided by the zinc electroplating. The following chart shows the possible range of corrosion protection, depend
