Zinc Plating

What is Zinc Plating?

Zinc plating is a soft, decorative, corrosion resistant finish. Zinc protects the substrate by sacrificing itself, corroding before the base metal. This means that the galvanic layer of zinc will protect even if the layer sustains minor damage, such as minor scratches and punctures.

The level of corrosion resistance of zinc plated fasteners depends on the thickness of the coating layer. To increase this corrosion resistance of zinc, a “chromate conversion” is usually added to deter the white colored oxidation products of zinc.

Zinc plated products, including zinc plated bolts, screws, nuts and washers, vary from one industry to another, however, they all share zinc’s durable finish, pleasant appearance and cost effective processing.

RoHS Compliant

Zinc and zinc alloy plating will surely become more significant as metals such as cadmium are phased out due to environmental regulations. Such sacrificial metals, such as zinc, have significant corrosion resistant properties in spite of their apparent softness and propensity to scratching.

What are the benefits of Zinc Plating?

• Zinc coatings are economical
• Protects even if slightly damaged on the surface
• Excellent modern substitute for less environmentally friendly cadmium coatings
• Great ductility and adhesion
• Consistent distribution
• Suitable for either rack or barrel plating
