Sheffield City Centre
City-centre blocks carry rooftop plant above live retail and offices, where roof weight limits favour lightweight GRP walkways. We prefabricate the route and install it in agreed access windows.
Sheffield's mix of process plant in the Don Valley, lab and plant-room estates around the universities and rooftop plant on city-centre blocks keeps corrosion-resistant access in steady demand. We design, fabricate and install GRP walkways, grating, handrails and access platforms with our own directly employed teams.

"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."
Sheffield GRP work runs from walkway routes over live production plant to riser flooring in converted mill buildings, and both reward one team owning the survey, the fabrication and the installation. We design, fabricate and install the whole package in-house, with the aftercare that follows.
Start your quoteYes. We work across Sheffield and beyond, with our own design, fabrication and installation teams covering GRP walkways, grating, handrails, stairs and access platforms.
Yes. GRP bolts together and we prefabricate and cut the route to fit off site, so the work on your site is largely assembly rather than hot works. We plan installs around production windows and out-of-hours access where the plant cannot stop.
Yes. Lightweight GRP walkways and step-overs suit roof weight limits and live buildings below. Our own CSCS-carded teams install the route with edge protection planned by our in-house Appointed Person.
Yes. We design, fabricate and install the whole structure, including a steel sub-frame to BS EN 1090 Execution Class 2 where the spans demand it, so one team owns the project from drawing to handover, and the aftercare that follows.
