What Paralloy & FVC does

Paralloy & FVC, operating through the Paralloy and Firth Vickers brands, is a UK-headquartered manufacturer of high-integrity centrifugally cast steel and nickel-based alloy components serving petrochemical, aerospace, industrial gas turbine, direct reduction iron, nuclear, defence, and general industrial customers worldwide. Founded in 1967 at Billingham (Paralloy) with roots stretching to 1914 in Sheffield (Firth Vickers), the group runs three foundries, two machine shops, and NADCAP-approved furnaces producing reformer tubes, ethylene cracking coils, inlet/outlet manifolds, aerospace compressor and exhaust casings, IGT rings and discs, and a proprietary materials portfolio of more than 70 alloys including patented grades such as OPTIM-AL (rated to 1200°C), H39WM+, PEP/Omega profiled tubes, and RED+/RED W for DRI applications.

The business operates a B2B custom-manufacturing model: revenue is generated through one-off orders for bespoke engineered components, complemented by precision machining, fabrication, and inspection services, with pricing negotiated per specification rather than on published rates. Commercial reach is delivered through direct enterprise field sales supported by a global agent network spanning the Americas, Europe, the Middle East, and Asia-Pacific, plus active participation in industry events such as Nitrogen + Syngas, EMET, and the European Ethylene Producers Conference. The customer base is concentrated among global petrochemical operators, aerospace OEMs, and turbine manufacturers, with some relationships exceeding 25 years and named engagement with SABIC.

Ownership sits with Nimbus, a private equity firm that acquired the centrifugal castings division from Doncasters Group in January 2020 backing the management team led by CEO Robert McGowan. Under Nimbus, the group has executed an active roll-up strategy: the aerospace division of Express Engineering (January 2021), Manoir Industries (June 2024), and Fonderies Hachette & Driout in France (March 2026) — the last combined with a strategic partnership with Framatome to establish sovereign nuclear and defence casting capacity under the Firth Vickers France brand. The group now operates from Billingham, Sheffield, Middlesbrough, and Grand Est (France) under the Paralloy, Firth Vickers, Manoir, and Hi-Tech brands.
