What Cellbeam does
Cellbeam Limited is a UK-based structural steel fabricator that designs and manufactures cellular beams, FABSEC-licensed beams, and bespoke plate steel sections (tee, box, cambered, tapered, and asymmetrical profiles) for the commercial construction, transportation infrastructure, shipbuilding, and offshore energy sectors. The company operates from a single manufacturing facility at Thorp Arch Estate in Wetherby, West Yorkshire, with weekly dispatch capacity of 250–300 tonnes and capability to produce beams up to 2.3m deep, 26m long, and 120mm thick using submerge arc welding and gas/plasma cutting systems.
Its technology stack centers on the proprietary FBEAM software, licensed from FABSEC, which enables virtual manufacture of cellular beam products, integrates fire protection engineering, and exports design data into BIM environments such as Tekla. As an officially licensed FABSEC fabricator, Cellbeam combines this design platform with automated plate cutting and welding production to deliver long-span structural solutions for landmark commercial projects including 52 Lime Street, 100 Liverpool Street, 10 Fenchurch Avenue, One Bank Street, and Manchester Airport.
Cellbeam is a subsidiary of the William Hare steel fabrication group and sells on a project-by-project quote-based model to construction firms, developers, and infrastructure clients primarily in the UK and Europe. Customer acquisition is enterprise field sales, supported by technical specification, an extensive portfolio of international certifications (AISC, CE Marking/BS EN 1090-1, ISO 9001, ISO 14001, ISO 3834, CWB, CSA, RISQS, BES 6001, CEMARS), and bundled passive fire protection through a partnership with Sherwin Williams.

Cellbeam competitors and assessment
Company assessmentDirect peers
- Severfield: Largest UK structural steelwork fabricator. Directly comparable to Cellbeam in fabricating structural steel beams and plate girders for UK commercial and infrastructure projects, though at substantially greater scale and broader product range.
- Donyatt Steel: UK structural and architectural steelwork fabricator. Comparable to Cellbeam in supplying bespoke steel sections and plate girders to construction projects of similar scope and complexity.
- BHC Ltd: Scottish-based structural steel fabricator serving UK commercial, infrastructure, and industrial projects. Comparable to Cellbeam as a competing specialist structural steelwork supplier bidding on similar project tenders.
- William Hare: Cellbeam's parent company and a major UK structural steelwork fabricator. Comparable as a direct peer because it operates in the same structural steel fabrication market, with overlapping customer base in UK commercial construction and infrastructure.
- Caunton Engineering: UK structural steelwork fabricator producing beams, plate girders, and cellular sections. Directly comparable product offering and customer base to Cellbeam in UK commercial and industrial construction.
- Adstone Construction: UK structural steelwork contractor delivering beams and girders for commercial and infrastructure schemes. Comparable as a competing regional structural steel fabricator.
Others
- FABSEC: Owner of the FABSEC cellular beam technology and FBEAM software that Cellbeam fabricates under license. Closely related via the licensing partnership and shared technology platform, but operates as licensor/engineering partner rather than competing fabricator.
- Voortman Steel Machinery: Manufacturer of CNC steel processing and fabrication equipment used by structural steelwork fabricators. Comparable as an enabling technology provider whose machinery defines the production capability tier at which Cellbeam operates (cutting, welding, profiling).
- Sherwin-Williams (Protective & Marine): Supplier of FIRETEX intumescent fire-protection coatings used on FABSEC beams manufactured by Cellbeam. Comparable as an adjacent ecosystem partner providing the certified fire-protection system that pairs with Cellbeam's beams.
Broad incumbents
- Barrett Steel: UK steel stockholder and processor with structural steel supply capabilities. Comparable as a broader incumbent in the UK steel supply chain that intersects with Cellbeam's market in raw material supply and finished structural members.
