Sheffield City Centre
S1 is city-core, with little land for a new portal frame, so the steel work here is mezzanines fitted within existing commercial blocks. We design these to suit the envelope.

Commercial Steel Buildings in Sheffield.
Sheffield's industrial estates and the Lower Don Valley need durable steel-framed buildings, from production units to warehousing and trade premises. We design, fabricate to BS EN 1090 and install the steel frame with our own directly employed teams.

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.

Sheffield steel buildings run from clear-span industrial and warehouse units in the Lower Don Valley to workshops and trade premises across the city. We design, fabricate and install the frame in-house, and stay on for the aftercare.

Common questions
FAQs
Yes. We work across Sheffield and beyond, with our own design, fabrication and installation teams.
Yes. Manufacturing and warehousing in the Lower Don Valley need wide clear spans and the eaves height for racking and plant. We design and fabricate the portal frame to BS EN 1090 Execution Class 2 and install it with our own teams.
Yes. Many units need a mezzanine or an integral office bay built into the frame. We design these in from the start, fabricate them with the main frame, and install the lot as one package.
Yes. We design, fabricate to BS EN 1090, and install the steel frame with our own directly employed teams, so one team owns the building from drawing to handover, and the aftercare that follows.
