Zinc Plating’s excellent corrosion resistance and cost-effectiveness make it the popular finish for the majority of hardware parts, which tend to be zinc, rather than cadmium plated.
Plating with zinc creates a deposit that is ductile, uniform and displays clean brilliance on all qualities of steel, including carbonaceous steel, cast and malleable iron.
The barrier of zinc coating prevents metal oxidation by acting as a sacrificial anode if the coating is damaged. The final zinc coating is soft and provides superb corrosion resistance.
Zinc plating passivation gives a choice of clear, gold, black and olive passivates as a final finish, or it can form a good base for future painting or powder coating.
