About this service

Buildings built to the site, not the catalogue.

A commercial workshop or storage building has to fit the site, the use and the cost, which is where a bespoke steel frame beats an off-the-shelf kit. We design, fabricate and install steel-framed workshops, storage buildings and covered structures for commercial and industrial clients, sized and specified for how they will actually be used. Every frame is made to your engineer's design under BS EN 1090 Execution Class 2 and erected by our own teams. For prefabricated garden garages and sheds, a kit-building retailer is the better fit; we build bespoke commercial structures.

Why UIS

Bespoke steel, built to the site and the use.

An off-the-shelf kit rarely fits a commercial site cleanly. We fabricate workshops and storage buildings to the span, height and layout the use actually needs, to BS EN 1090 Execution Class 2, and install with our own teams, so the building suits the site rather than the site working around the building.

Why choose UIS

Why bespoke beats a kit for commercial use.

A commercial building should fit the site and the use, not force them to fit a standard box.
