What we provide to you

Services

At Concem, we specialise in high-quality zinc electroplating with fast, reliable turnaround times. Our dedicated zinc plating plant delivers consistent corrosion protection and professional finishes for engineering, automotive, hardware, and industrial components.

We focus exclusively on zinc electroplating — no distractions, just expert results you can trust. Whether you need barrel plating for high-volume small parts or jigging for larger or delicate components, we plate to a precise thickness of 8–15 microns and offer a full range of passivation finishes.

Zinc Electroplating (8–15 Microns)

We apply a uniform, high-quality zinc coating that provides excellent cathodic protection against rust and corrosion. The 8–15 micron thickness range meets most engineering and automotive specifications while maintaining cost-effectiveness and fast processing. Ideal for steel components that require long-lasting durability in demanding environments.

Barrel Plating

Ideal for high-volume production of small to medium parts such as bolts, nuts, fasteners, washers, brackets, and hardware. Parts are gently tumbled in a rotating barrel, ensuring even zinc coverage on all surfaces.

Benefits:

  • Highly economical for bulk orders
  • Consistent and uniform finish
  • Fast processing with quick turnaround times

Jigging / Rack Plating

Suited for larger, more complex, delicate, or high-value components. Parts are securely racked on custom or standard jigs to prevent contact damage and achieve precise plating on every contour and surface.

Benefits:

  • Superior control and even coverage on intricate shapes
  • Protects delicate or finished surfaces
  • Perfect for low-volume or specialised runs

Passivation Finishes

We enhance every zinc-plated component with high-performance chromate conversion coatings (passivation) to boost corrosion resistance and provide an attractive final appearance:

Black Passivation

Offers a sleek, modern black finish with superior corrosion protection. Popular for automotive and industrial parts where aesthetics and durability are important.

Yellow Passivation

Classic iridescent golden-yellow finish known for excellent corrosion resistance.

Blue Passivation

Bright, clear-blue finish that delivers a clean, professional look with reliable protection.

All passivation is performed in-house under strict quality control for consistent colour and performance.
