Protection starts
at the surface.
Zinc electroplating puts a protective zinc layer onto suitable metal components. At Metal-lech, our focus is straightforward: zinc plating in three finishes, with barrel and jigging work to suit the component.
From a box of fasteners to a batch of components, the starting point is the same — understanding the part, the finish and the job.

Choose your finish.
Three distinct appearances. Select the finish your component needs, or ask us to help you work through the options.
Yellow zinc
A yellow-gold appearance with characteristic iridescence. A distinctive finish for zinc plated components.
Black zinc
A dark charcoal-to-black appearance for parts that need a less reflective, darker zinc finish.
Illustrative finish images. Actual colour and sheen depend on the component, surface condition and specified treatment.
Barrel plating
Small components.
A focused process.
Barrel work brings suitable small parts together for batch zinc plating. A practical process for components that can move together during plating.
- 01 Nuts, bolts, washers and small metal parts
- 02 Blue, yellow or black finish options
- 03 Part suitability reviewed before quoting
Jigging / rack plating
Jigging work.
Each part in place.
Components are secured individually on a jig or rack during zinc plating. An option for parts whose shape or handling requirements make them unsuitable for tumbling in a barrel.
Available in blue, yellow and black zinc finishes. Send a photo or drawing, dimensions and quantity so we can review the work with you.
