Zinc Plating

Zinc Plating Clear and Yellow per ASTM B633

Zinc Plating is the electrolytic application of zinc by immersing clean steel parts in a chloride zinc solution and applying direct current. Douglas Finishing has both rack and barrel plating capabilities. We offer a clear chromate (trivalent chemistry – RoHS compliant) as well as a yellow chromate (hexavalent – not RoHS compliant). For heat treated and high strength steel parts, we have the capability to bake the parts to reduce hydrogen embrittlement. We can coat parts as large as 96″ long x 28″ deep x 20″ wide.
  RoHS Compliant on Clear only.
