Surface Finishing Options

Choose the right finishing process based on appearance, material, durability, and working environment.

Anodizing

Common for aluminum parts, improving corrosion resistance and appearance.

Hard Anodizing

Provides higher wear resistance and a stronger protective oxide layer.

Black Oxide

Used for steel parts to provide a dark appearance and mild corrosion protection.

Passivation

Improves corrosion resistance of stainless steel by removing surface contaminants.

Zinc Plating

Provides corrosion protection for steel components and industrial hardware.

Nickel Plating

Improves wear resistance, corrosion protection, and surface appearance.

Powder Coating

Durable colored coating for metal parts, housings, panels, and brackets.

Polishing

Improves surface smoothness and visual appearance for cosmetic or functional needs.

Additional Finishing & Marking

We can also support marking, printing, blasting, and other secondary processes based on your product requirements.

Sandblasting

Creates a uniform matte surface and prepares parts before anodizing or coating.

Brushing

Produces a directional surface texture for decorative metal parts.

Laser Marking

Permanent marking for logos, serial numbers, part numbers, and traceability.
