Surface Treatment

Description & Applications

Dacromet

A chrome-free zinc coating offering excellent corrosion resistance. Suitable for automotive and industrial equipment exposed to harsh environments.

Galvanizing (Zinc Plating)

Zinc coating applied through electroplating or hot-dip, providing strong corrosion protection. Common in construction, outdoor machinery, and pipelines.

Black Oxide (Blackening)

A chemical oxidation process that creates a black, protective layer on steel. Ideal for mechanical parts, automotive components, and tools where appearance and corrosion resistance are important.

Zinc-Chromate Coating

Nickel Plating

A nickel coating providing high hardness and excellent corrosion resistance, with a smooth surface. Used in electronics, precision parts, and industrial applications requiring high gloss and protection.

Phosphating

A process that forms a phosphate layer on the metal surface, improving adhesion and corrosion resistance. Used in automotive and machinery applications requiring good paint adhesion.

Aluminum Spraying

A coating of aluminum sprayed onto steel surfaces for heat and corrosion resistance. Used in high-temperature environments like boilers and engines.

Passivation

A process that enhances the corrosion resistance of stainless steel or aluminum by creating a protective oxide layer. Common in food processing, pharmaceutical, and medical equipment.

Coating (Polymer, Resin)

A thin film of polymers (e.g., polyurethane, epoxy) applied to the surface for corrosion resistance and wear protection. Used in electronics, appliances, and architectural applications.
