Zinc plating
Zinc plating is identical to electro-galvanizing in principle because both are electro-deposition processes. Zinc plating is typically used for smaller parts that will be exposed in interior or mildly corrosive conditions. For use in moderate or severe environments, the materials must be chromate-conversion coated for additional corrosion protection. Akron plating offers a wide range of chromate conversions and if you are looking for a specialty coating please contact us for quoting.
