H. Petit & Cie

What H. Petit & Cie does

H. Petit & Cie is a French industrial engineering and fabrication firm founded in 1946 and headquartered in Aubenas, France, operating as a subsidiary of the diversified group Groupe RCA. The company designs, fabricates, installs, and maintains metal structures, ventilation systems, and industrial equipment for three principal verticals: tunnels and underground infrastructure, cement plants/quarries/mines, and general industry. Core service lines include boilermaking and metalwork (Chaudronnerie/Métallerie) executed in a 3,000 m² production facility; on-site installation and maintenance; industrial handling and machine transfer; equipment rental for provisional ventilation; and a bureau d'études (BE/Ingénierie) using TOPSOLID CAD/CAE software for 2D/3D design, resistance calculations, and finite element analysis.

The business model centers on enterprise field sales and direct engagement with industrial project managers and technical decision-makers, with a go-to-market motion built around turnkey project delivery that spans engineering studies, custom fabrication (in stainless steel, aluminum, cast iron, copper, and steel), surface treatment (metallization, powder epoxy coating, galvanization), handling with an owned fleet (26-ton flatbed truck with 32tm crane, forklifts, transport vans), and on-site assembly. Revenue is generated through one-time custom fabrication orders, managed turnkey projects, professional installation and maintenance services, and a usage-based equipment rental stream. Customer concentration is anchored in heavy industry segments with quote-based, non-publicly-disclosed pricing on each engagement.

The company holds MASE safety certification (since May 2018) via the MASE Rhône Alpes association and partners with Officine Conterno to deliver complete quarry and aggregate processing solutions, signaling a vertical extension from component fabrication into integrated systems delivery. Operations are principally regional (France) with international reach limited to industrial machine transfer projects.
