Accreditations
Certifications for structural steel and metal fabrication
Our structural steel supply and metal fabrication operate under an independently audited management system: BS EN 1090-2 Execution Class 3 for fabrication, ISO 9001 for quality, and an ISOQAR-accredited Welding Quality Management System covering BS EN 9606-1 coded welders.
Annual external audits confirm that our Factory Production Control matches what we ship — so every Declaration of Performance, mill certificate and weld record we issue is backed by a live, audited process.
What the paperwork covers
CE / UKCA marking under BS EN 1090, EN 10204 3.1 material certs, welder qualification records and a project-specific Inspection & Test Plan — issued as a single pack with every order through our compliance and reporting workflow.
Built into every fabrication
Certification isn't a bolt-on. It is wired into every job that passes through our metal fabrication workshop, from material booking-in to dispatch — so what you specify is what you get, with the paperwork to prove it.
