Steel Fabrication in Sheffield.

Sheffield built its name on steel, and the city's advanced-manufacturing plants and regenerating centre still need steel and metalwork fabricated to a high standard. We design, fabricate to BS EN 1090 and install structural and secondary steel with our own directly employed teams.

Start to finish

One team, from drawing to installed.

Sheffield fabrication runs from heavy production-line steelwork in the Lower Don Valley to architectural and secondary steel for city-centre schemes. We design, fabricate and install the lot in-house, and stay on for the aftercare.
