Chrome Plating
Chrome plating and chromate treatment applied to fasteners for decorative, corrosion resistance, and wear-resistance applications. Hexavalent chrome (Cr VI) and trivalent chrome (Cr III) options available. Commonly specified for automotive, architectural, and OEM equipment fasteners requiring a bright, hard-wearing surface finish.

Chrome plating and chromate treatment are two distinct surface finishing processes applied to fasteners, often confused but serving different functions.
Chromate Treatment (Conversion Coating):
Chromate treatment is a chemical conversion coating applied over zinc-plated fasteners (as a passivation step) or directly on aluminium fasteners. It produces a thin (0.5–5 µm) film that significantly improves corrosion resistance and paint adhesion.
- Hexavalent Chromate (Cr VI): Traditional yellow iridescent finish; excellent corrosion protection; restricted in Europe under RoHS but still permitted for many industrial and defence applications
- Trivalent Chromate (Cr III): RoHS-compliant alternative; clear or blue-tinted finish; excellent corrosion performance
Decorative Chrome Plating:
Decorative chrome plating involves depositing a thin (0.1–0.5 µm) chrome layer over a nickel undercoat on a copper base layer. The result is a bright, mirror-like finish with excellent hardness and moderate corrosion resistance.
Hard Chrome Plating (Functional Chrome):
• Coating Thickness: 25–500 µm
• Hardness: HV 850–1100
• Application: Fasteners and components requiring extreme wear and abrasion resistance
• Common in hydraulic, aerospace, and heavy machinery fasteners
Asia Bolts Industries supplies chrome-plated and chromate-treated fasteners per client and project-specific requirements. All supply is documented with finish type (hexavalent vs trivalent), plating thickness, and material certificates.
