Pro Steel Engineering

What Pro Steel Engineering does

Pro Steel Engineering Limited is a privately held UK structural steelwork specialist, founded in 2012 and headquartered in Pontypool, South Wales, with a second office opened in 2025 at Heathrow. The company designs, fabricates, and installs structural steel for major infrastructure and built-environment projects, holding the BS EN 1090 Execution Class 4 certification — the highest accreditation level for fabricated steelwork under European standards — alongside ISO 9001, ISO 14001 and ISO 45001. Its core technical differentiator is a kit-of-parts / Design for Manufacture and Assembly (DfMA) methodology that shifts work off-site into larger pre-assembled units; the company reports this approach reduced on-site build time at Manchester Airport Pier 2 from 110 days to 12 days and prevented 125 tonnes of CO₂ emissions across that single project.

The business operates a project-based, direct enterprise sales model targeting main contractors, infrastructure owners, and public-sector clients across five priority verticals: Aviation (Heathrow, Manchester, Bristol), Rail (Transport for Wales, Network Rail schemes), Highways (A465 Heads of the Valleys), Sport & Tourism (Principality Stadium SCALE, Alexandra Palace Rooftop Climb), and Historic Structures (Newport Transporter Bridge, Olympic Stadium strengthening). Revenue is generated one-time per contract via negotiation against project scope, tonnage, and complexity — evidenced by flagship commissions including 4,000+ tonnes at the London Olympic Stadium and 1,400 tonnes at Manchester Airport Pier 2 — supplemented by standalone professional services for site supervision and bespoke commissions for landmark structures. The company is a founding member of the 12-partner Celtico Engineering Solutions Alliance, which collectively represents £250m+ annual turnover and provides single-point engagement for major UK renewable-energy and infrastructure pursuits, and has begun exporting internationally, including a £1.1m UK Export Finance-backed bridge-girder contract near Kyiv.

In the most recently reported fiscal year (FY2024) Pro Steel recorded £17m of turnover against a headcount of 11–50, implying revenue per employee well above sector averages for mid-market steel fabricators. The senior leadership team — Co-Founder and Director Richard Selby, Commercial Director Jon Davies, Operations Director Haydn Roberts, and a recently expanded functional bench covering Finance, SHEQ, HR, Quality and Engineering Management — is investing in organisational buildout, including new ERP implementation, consistent with a multi-project scaling phase.

Scale indicators5 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Severfield: UK's largest structural steel fabricator listed on AIM, with revenue exceeding £400m and multi-site fabrication capacity. Comparable because it operates in the same structural steel fabrication space serving UK construction and infrastructure clients, though at substantially larger scale and broader market exposure.
• William Hare: Privately held UK structural steel group with international operations delivering fabricated steel for buildings, infrastructure, and nuclear projects. Comparable as a direct competitor for large UK infrastructure tenders including HS2, stadiums, and commercial developments.

Direct peers

• Bourne Steel: UK-based structural steel fabricator delivering projects across commercial, residential, and infrastructure sectors. Highly comparable in service offering (fabrication, installation, project management) and in operating as a mid-sized specialist serving main contractors and developers.
