Leeds City Centre
Leeds city-centre frames thread through the South Bank regeneration on live streets. We phase deliveries into weekend and night windows and erect with our own crews.

Structural Steelwork in Leeds.
Leeds runs one of the largest regeneration programmes in the North, from South Bank towers to the Aire Valley industrial corridor, and that scale needs dependable structural steel. We design, fabricate to BS EN 1090 and install every 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.

Client reviews
"I've worked with UIS for several years on some high profile and very complex projects. Their attitude and work ethic are second to none - providing high quality services and products which are delivered safely and on time every time. Overall they are a pleasure to do business with and wouldn't hesitate recommending UIS for any steelwork or metalwork packages."
Start to finish
One team, from drawing to installed.
Leeds work spans high-rise city-centre frames and Aire Valley industrial units, and both run better under one accountable team than a split package. We design, fabricate and install in-house, and stay on for the aftercare.
