Zinc Plating & Passivation
from ETR Metal Finishing
Zinc plating is usually used to provide a greater degree of corrosion protection for less noble metals such as mild steel. The application of a post-plating passivate film can further enhance corrosion protection. We provide trivalent clear/blue passivate and trivalent colour passivate and also trivalent black passivate with a lacquer topcoat which are all ELV, RoHs and WEEE compliant.
