Ateliers Bois et Cie

What Ateliers Bois et Cie does

Ateliers Bois et Cie is a French metal construction (charpente métallique) company founded in 1881 and headquartered in Chaumont, Haute-Marne. The firm designs, fabricates, and assembles steel structures, roofing, cladding, and metalwork for industrial and public-sector clients, operating from a 17,000 m² covered workshop with a 2,850-tonne steel yard and currently employing approximately 83 people. Its customer base spans large industrial groups (ALSTOM, RENAULT, SOLVAY, ORANO, TOTAL/TotalEnergies, EDF) and public operators (SNCF, RATP, SYCTOM de Paris), with Île-de-France representing roughly 50% of revenue and additional coverage across Rhône-Alpes, Grand-Est, Bourgogne Franche-Comté, Picardie, and Normandie via a Lyon agency.

The company runs an integrated, turnkey delivery model: an in-house CAD/DAO design bureau (established 1990) handles engineering, fabrication is performed in-house, and the firm's own assembly teams execute on-site installation, supported by a quality manual and per-client quality plans. It holds ISO 9001 / NF EN 1090-1 (CE marking), MASE (enabling nuclear and SEVESO high-threshold site access), Qualibat, and SNCF approved-contractor certifications. A 2021 high-speed profile drilling and milling line, financed under the French government's Relance plan, expanded fabrication capacity.

Revenue is generated through project-based one-time contracts — custom-quoted based on specifications and bid through direct negotiation with enterprise clients and competitive tenders for public-sector work. Pricing is not publicly disclosed. The company is privately held, with leadership having transitioned in 2023 from Sébastien Villame to Jean-Philippe Claudel, marking a continuation of non-family executive leadership that began when Philippe Pepe took over as PDG in 1997. No funding rounds, institutional investors, parent company, or M&A activity are disclosed in the available data.
