Welcome to CR Steel
Specialist Structural Steel Contractors
CR Steel is a UK structural steel and metal fabrication contractor supplying developers, principal contractors and framework specialists across energy, data centres, rail, healthcare, commercial and industrial sectors — built in a workshop that treats quality, traceability and on-time delivery as contractual obligations, not optional extras bolted on at the end.
Competitive mill-indexed pricing, CE / UKCA marking under BS EN 1090 EXC 3, ISO 9001 fabrication and a complete digital certification pack issued with every order — administered in-house, so the compliance side of structural steel never slows your programme down.
Why CR Steel
Structural steel supply and metal fabrication, built around your programme.
We supply structural steel sections and fully fabricated packages — universal beams, columns, hollow sections, channels, angles, plates and bespoke assemblies — cut, drilled, welded and delivered to programme across the UK. From a single substation gantry through to full multi-storey commercial frames, the same accredited workflow applies: priced from your requirements, fabricated to BS EN 1090 EXC 3, and delivered into a slot booked against your erection sequence.
Fabrication sequenced to your erection plan
Our metal fabrication workshop delivers structural frames, mezzanines, stairs, plant decks, gantries, MEP support steel and bespoke architectural steelwork for tier 1 and tier 2 contractors. Coded welders, in-house engineers and CAD detailers, a dedicated project manager and weekly red/amber/green reporting keep every package moving from drawing review through to dispatch — with live production status visible to your buyer, PM and site team in one workspace.
Certified, traceable, audit-ready
Every order ships with a complete handover dossier: CE / UKCA Declaration of Performance, EN 10204 3.1 mill certificates traceable to heat number, WPS / PQR weld records, NDT and inspection sign-off. Our Factory Production Control is independently audited under BS EN 1090 and ISO 9001, supporting DNO adoption, framework prequalification and principal contractor sign-off — so the structural steel you receive matches the structural steel you specified, on paper and on site.
