Steel Fabrication across Yorkshire.
Steel fabrication has shaped Yorkshire for generations, and it runs through our workshop every day. For projects across Sheffield, Leeds, Doncaster and the wider county, we design, fabricate and install bespoke steelwork, welded in-house by coded welders to BS EN ISO 9606.

Accredited for design, fabrication and installation, with the paperwork to prove it.
- BS EN 1090 Execution Class 2, UKCA marked: the execution class your engineer's design legally has to be fabricated to.
- Coded welders, BS EN ISO 9606: every structural weld made by an approval-tested welder, traceable on the documentation.
- ISO 9001 quality management: a quality system audited end to end, not a badge on a footer.
- CHAS Elite, SafeContractor & ConstructionLine Gold: the pre-qualification pack your procurement team lifts straight into a PQQ.
- GBP 10m public and GBP 10m employers liability: published figures, because your procurement team needs them on file.
- Directly employed, CSCS-carded site teams: the people on your site are ours, not subcontracted, so one team owns the result.

Yes. We work across Yorkshire and beyond, with our own design, fabrication and installation teams.
Yes. We design, fabricate to BS EN 1090, and install steel fabrication with our own directly employed teams, so one team owns the project from drawing to handover, and the aftercare that follows.
Every project is priced on its drawings, tonnage, finish and access. Send us a drawing or a one line brief and you will get a fixed quote, not a ballpark.
Standard programmes run 4 to 6 weeks from approved drawings to installed. Tighter programmes are quoted against your deadline.
