Clifton Moor
Clifton Moor carries York's largest spread of retail, trade and light-industrial frames, where extensions and mezzanine retrofits are steady demand. We design new steel around live trading next door.
Commercial Steel Buildings in York.
York's commercial growth runs around its outer ring road, from Clifton Moor and Monks Cross to the business parks at Poppleton, while the walled centre keeps planning tight. We design, fabricate to BS EN 1090 Execution Class 2 at our South Yorkshire workshop and install commercial steel buildings across the city 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.

Common questions
FAQs
Yes. We design in-house, fabricate at our South Yorkshire workshop and install across York and the surrounding Vale with our own directly employed teams, delivering on our own transport.
Yes. York's conservation setting means scale, cladding and rooflines get real scrutiny, so we coordinate the structural package with your architect and planner, and detail the frame to the approved envelope rather than a standard catalogue shape.
Yes. Plots near the rivers typically need floor levels set above the design flood line and services lifted to match. We design the frame and base details to the flood requirements in your approval.
Yes. The arable estates around the city need grain stores, machinery sheds and general-purpose buildings. We design, fabricate and install clear-span frames sized to the holding, with galvanised steelwork as standard.
BS EN 1090 Execution Class 2 with UKCA marking, coded welders to BS EN ISO 9606, ISO 9001, CHAS Elite, SafeContractor and ConstructionLine Gold, backed by GBP 10m public and GBP 10m employers liability.
The footprint and eaves height, intended use, site postcode, your target dates and whether you need installation as well as the frame. Drawings are ideal; a dimensioned sketch is enough to start.
