Coating Technology

Advanced Surface Treatment Solutions

Advanced electroplating processes and surface treatment technologies engineered to deliver superior corrosion resistance for industrial fasteners in demanding environments. We maintain in-house surface treatment capabilities and partnerships with specialized plating facilities.

Why Coating Matters

Corrosion is the primary failure mode for fasteners in automotive, energy storage, and industrial applications. Unprotected steel fasteners exposed to moisture, salt, and chemical environments degrade rapidly, compromising structural integrity and safety.

Effective coating systems provide a barrier layer that prevents direct contact between the base metal and corrosive agents. The performance depends on coating composition, thickness uniformity, adhesion quality, and post-treatment processes.

Coating Types

Zinc-Nickel Plating

  • Alloy coating with 12-15% nickel
