Steel Lintel Suppliers
Bespoke steel lintels for self-builders, domestic contractors, and main contractors - fabricated to your engineer's schedule and UKCA-marked to BS EN 1090 EC2.

















What we deliver.
Universal Industrial Services supplies and fabricates steel lintels for self-builders, domestic contractors, residential architects, and main contractors across the UK from Rotherham. Quotes come back same-day on small domestic enquiries and in 1-2 weeks on large commercial packages. Every lintel is fabricated to the structural engineer's calculations under BS EN 1090 Execution Class 2, with installation support available and a 12-month defect liability period. Trading since 1994, family-owned and second-generation run, with CHAS Elite, Alcumus SafeContractor, ConstructionLine Gold, and £10 million each of PL and EL cover.
What we make.
Every project follows the same certified workflow - so you get the same outcome whether we're making one beam or a thousand.
Bespoke in-house fabrication
We fabricate your lintels at our Rotherham workshop rather than passing an order through a stockist's warehouse. Welded plate assemblies, compound beams, non-standard spans - we make it.
Explore →Engineer-led detailing
We fabricate to your structural engineer's calculations, not to a generic lintel selector. Send us the engineer's schedule with span, bearing lengths, loading, and connection detail - our drawing office prepares shop drawings for approval before any steel is cut.
Same-day domestic quoting
Small domestic lintel enquiries come back same-day rather than waiting a fortnight. Larger commercial packages take 1-2 weeks because a proper take-off against the general arrangement drawings deserves a considered price. Your figure includes fabrication, dispatch timing, and installation support.

"As a self-builder of an innovative eco-home, I needed to partner with a company who offered competence, a willingness to push themselves and the resilience to stick with me during the challenging times. UIS built the metal structure of my property and added creative finishing touches - I trusted them to build a bespoke staircase, balcony and front gates for my house."
Questions clients ask us.
We fabricate to your structural engineer's calculations - we don't size the lintel for you. Send the engineer's schedule with span, bearing lengths, and loading, and we'll turn that into a UKCA-marked piece of steel on the day the bricklayers need it. This keeps the compliance chain clean: engineer owns the design, we own the fabrication to the design.
Same-day on small domestic lintel enquiries. 1-2 weeks on larger commercial packages where we're pricing against the general arrangement drawings and a coded welding plan. A homeowner enquiring on Monday about an extension opening should have a price that day.
Yes - every fabricated lintel is UKCA-marked to BS EN 1090 Execution Class 2 under Factory Production Control. Mill test certificates, weld procedure specifications where applicable, and the traceability pack Building Control and your structural engineer expect - shipped with the lintel.
Yes - our site team can install as well as supply, led by an SSSTS supervisor with CSCS, PASMA, and IPAF certification. Coordination with the bricklayers on programme, handover documentation, and the 12-month defect liability - through one named point of contact.
Where the work falls inside our installation scope, yes - we handle Part A structural sign-off correspondence with your Building Control surveyor as part of the package. If we're supply-only, the Building Control submission stays with you or your structural engineer.
UK-wide from our South Yorkshire workshop. Directly employed crews have delivered and installed from Scotland to central London, and local delivery is on our own flatbeds rather than forced into a third-party depot's routing plan.
