Recent moves5 records

Expansion highlights5 records

Broad incumbents

• Hadley Group: UK-headquartered manufacturer of cold-formed steel sections and prefabricated structural solutions with a much broader product portfolio. Comparable in being a fabricator supplying construction but operates at significantly larger scale and product breadth.
• Barrett Steel: One of the largest independent steel stockholders and processors in the UK and Ireland. Comparable supply-chain positioning in structural steel supply, though at much larger scale and broader product scope than McMenamin's project fabrication focus.

Direct peers

• BHC Steel: UK-based structural steel fabricator delivering large commercial, industrial, and infrastructure projects. Direct competitor profile — both operate as structural steel fabricators and erectors serving similar end markets in the UK and Ireland.
• John W. Laycock Ltd: UK-based structural steelwork contractor providing fabrication and erection services for commercial, industrial, and education projects. Closely comparable in service offering (steel fabrication + erection) and customer profile to McMenamin Engineering.
• Real Steel Engineering: Irish structural steel fabrication business serving industrial and commercial construction. Comparable in offering, geographic focus, and scale tier to McMenamin Engineering.

Others

• Voortman Steel Group: Netherlands-based manufacturer of CNC steel processing and fabrication machinery. Adjacent ecosystem peer — McMenamin Engineering operates Voortman-comparable CNC drill/saw and plasma cutting equipment, making it both a potential customer and a representative benchmark for modern fabrication capability.
