What Gami Group does
Gami Group is a privately held French industrial equipment manufacturer headquartered in Corbas, Auvergne-Rhône-Alpes, operating five wholly-owned subsidiaries (Gami Précision, G. Constructions Mécaniques, Gami Cryo & Méca, Turbolub, Espace CN) and approximately 165 employees across five production sites in the same region. The group designs, manufactures, and assembles custom industrial equipment — precision machined parts, mechanical sub-assemblies, complex welded structures, and bimetallic aluminum/stainless-steel transition joints (T+C Transition Joints) co-developed with CEA since 1978 for cryogenic, nuclear, hydrogen, Oil and Gas, and aerospace/maritime applications.
The technical core is precision metalworking (carbon steel, stainless steel, aluminum, Inconel, titanium, bronze, brass) supported by CNC lathes, horizontal/vertical machining centers, cylindrical grinding, 3D measurement benches, welding logbooks compliant with NF EN 15614 / ASME, and a 6,000 m² assembly and testing footprint with overhead cranes up to 10 tons and hydrostatic test capability up to 400 bar. Bimetallic transition joints are produced by hot stamping and thermal expansion with full traceability from casting to finished part, helium leak-testing to 10⁻⁹ mbar·l·s⁻¹.
Revenue is generated through project-based, custom-industrial-equipment contracts sold direct to enterprise accounts (grands comptes) in five primary segments — nuclear/energy, defense, Oil & Gas, transport (aeronautical, aerospace, automotive, railway), and equipment assets — with end-to-end scope from feasibility study through on-site installation. Pricing is undisclosed, certifications (ISO 9001, DESP 2014/68/UE, ASME VIII div.1, Rolls-Royce Certificate of Approval) underwrite eligibility for safety-critical nuclear and defense contracts. Go-to-market is enterprise field sales supported by industry exhibitions (WNE, Global Industrie, Hyvolution) and trade association memberships (GIFEN, Nuclear Valley, France Hydrogène, Cetim, UIMM).
