KEY FAILURE RISKS

Thread Corrosion

Exposure to moisture and contaminants can cause rust formation on threaded areas.

Torque Variation

Inconsistent coating friction may affect tightening and clamp load behaviour.

Hydrogen Embrittlement

Electrolytic coatings can introduce failure risks in high-strength fasteners.

Fitment Issues

Excess coating thickness can interfere with thread engagement and assembly.

OUR COATING CAPABILITIES

At REMAQ, we deliver zinc flake and zinc plating solutions that protect safety-critical components from corrosion, hydrogen embrittlement, and performance failure across demanding industrial applications.

CONTROLLED COATING PROCESS

Step 01

Incoming Inspection

Fasteners are inspected for material grade, thread condition, and coating suitability before processing.

Step 02

Surface Preparation

Mechanical cleaning ensures proper adhesion without introducing hydrogen embrittlement or thread damage.

Step 03

Coating Application

Coating is applied using controlled methods to achieve uniform coverage across threads and bearing surfaces.

Step 04

Curing & Dispatch

Coated fasteners are cured, inspected, and packed to preserve surface condition and coating integrity.
