Our services
Zinc, zinc-nickel and polishing under one roof — non-cyanide alkaline baths and trivalent (Cr³⁺) passivation throughout, with every lot inspected.
P-43 · interimNon-cyanide alkaline zinc with trivalent passivation in silver/blue, yellow or black — cost-effective rust protection for automotive parts.
P-46 · interimAlkaline zinc-nickel alloy with high corrosion resistance for underbody parts, tubes, shafts and hubs — nickel content checked by XRF.
P-27 · interimWe polish out die marks, impact marks and dents so parts are smooth before plating.
