Galvanised Fasteners

High-integrity galvanised fasteners and corrosion-resistant bolting solutions engineered for exposed, marine, and outdoor environments.

Offering custom manufacturing capabilities for specialised projects, providing weather protection solutions tailored to precise structural specifications.

We manufacture an extensive range of custom fasteners and threaded components designed to withstand the elements where quality and corrosion resistance are of major importance. Ideal for outdoor, marine, leisure, and industrial environments, we ensure that components are engineered to prevent premature degradation and guarantee secure, long-term performance.

Alongside our core bespoke manufacturing capabilities, including custom-forged bolts, studs, and threaded components, we work closely with approved specialist coating partners to apply required protective finishes when specified by the project.

Note: Due to hydrogen embrittlement considerations, specific high-strength grade limitations apply to certain surface treatments.

Understanding Hydrogen Embrittlement and Surface Protection

Hydrogen embrittlement is a metallurgical phenomenon where high-strength metals become brittle and prone to sudden structural failure under tension.

It occurs when atomic hydrogen diffuses into the metal matrix during manufacturing processes like acid pickling or electro-plating. Under load, these trapped hydrogen atoms create internal pressure, significantly reducing ductility and causing unexpected cracking without prior visible warning.

This is highly relevant to structural fasteners and foundation bolting operating under high tensile loads. Because sudden failure can have catastrophic consequences, strict engineering protocols govern surface treatments. This includes restricting certain electrolytic coatings to material grades 8.8 and below, or mandating immediate post-treatment baking (stress relief) to drive out trapped hydrogen and ensure long-term structural integrity.
