York city centre
Inside the walls, structural work means floor strengthening, trimming around new stairs and lifts, and beams threaded into retained buildings. We detail for piece-small erection where cranes cannot work.
Structural Steelwork in York.
York's structural work splits between the walled centre, where steel goes in beam by beam behind retained frontages, and the ring-road business parks, where frames, mezzanines and walkways carry the commercial growth. We design in-house, fabricate at our South Yorkshire workshop to BS EN 1090 Execution Class 2 and install across the city with our own directly employed teams.

Common questions
FAQs
Yes. Beams, columns and trimming steel for commercial refurbishments and structural alterations are our standard work. We fabricate to BS EN 1090 Execution Class 2, deliver on our own transport and install with directly employed crews.
Yes. Much of the centre means restricted access, no crane positions and party structures, so we detail connections for piece-small erection and hand-balanced installation, coordinated with your engineer and the conservation officer's conditions.
Yes. Access walkways, gantries, plant platforms and mezzanine floors run through the same design, fabrication and installation route as our frames, with handrails and flooring delivered as part of the package.
Either. We can take your structural engineer's design and deliver the connection detailing, fabrication and erection, or carry the structural design in-house where the project suits it. One company stays accountable through to the aftercare.
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 engineer's or architect's drawings if you have them, the beam sizes or spans involved, the site postcode, your programme dates and whether you need installation as well as supply. A marked-up sketch is enough to start the conversation.
