Clear and Yellow per ASTM B633 Bobcat Spec PS-P
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 high strength steel parts, we have the capability to bake the parts to reduce hydrogen embrittlement. We can coat parts as large as 96″ wide x 20″ high x 28″ long.
