Why use zinc plating?
Zinc plating provides excellent corrosion resistant and a great base for paint, powder coating or printing on all types of sheet metal, machined components and parts made of steel, brass, copper, bronze and iron. It's also quick to apply, highly cost-effective, and can provide an attractive finish, whether clear, black or coloured.

How does zinc plating work?
Zinc electroplating is a form of galvanisation that adds a thin layer of zinc into components. When applied to steel, zinc plating becomes a sacrificial anode, so that the plating protects the underlying material from scratches and damage.

Choose your zinc plating colours
Zinc plating can be passivated to give it corrosion resistance and also add colour if you wish. Choose from

• standard colour (yellow iridescent or rainbow style finish)
• trivalent colour (iridescent green-yellow colour, RoHS compliant process)
• clear (blue-ish tint, RoHS compliant process)
• black (excellent decorative finish, RoHS compliant process)

Choose your zinc plating thickness
We can apply plating of between 5 and 25µm (micrometres or microns), with other thicknesses on request. Since zinc plating is deposited on the surface of the component, the final finished size will increase by the thickness of the coating. A coating of 12µm or more provides excellent protection against corrosion in marine environments, withstanding salt spray tests of over 500 hours.

Alkaline zinc (bright acid zinc)
The alkaline zinc process solves the problem of adhesion failures, making it ideal for iron castings and fixings. It also provides a level surface over the whole item, and can be used to achieve thicker coatings than standard plating.
