Benefit
Our Barrel Zinc products are RoHS (Restriction of Hazardous Substances) compliant. Hexavalent chromium is the concern with chromate conversion coatings on zinc. The RoHS Directive restricts hexavalent chromium, but does not restrict less hazardous trivalent chromium, which is used in our zinc processing. Zinc trivalent chromate coatings, also called zinc passivation coatings, provide an excellent, inexpensive, attractive finish and good corrosion resistance.
