CMB (Constructions Métalliques du Berry)

What CMB (Constructions Métalliques du Berry) does

CMB (Constructions Métalliques du Berry) is a privately held French metal construction firm founded in 1970, headquartered in Saint-Germain-du-Puy near Bourges (Cher department), and operating as a Société par actions simplifiée (SAS) with €400,000 registered capital under the MAQ group. The company delivers three integrated service lines—turnkey buildings (Bâtiments Clés en Main), specialized metal construction (Constructions Métalliques), and structural rehabilitation (Réhabilitation)—covering design studies, structural calculations, fabrication, and erection entirely in-house without subcontracting. It maintains 25 in-house specialists including engineers, draftspersons, welders, and erectors, and holds FFB and QUALIBAT certifications.

The firm operates through two geographic divisions: a Centre-Val de Loire/Bourgogne turnkey building division serving commercial, industrial, and artisanal clients, and an Île-de-France metal construction and rehabilitation division serving architects, general contractors, and public authorities on complex urban projects. Revenue is generated through project-based, quote-driven contracts (no public pricing disclosure) with the company acting as maître d'œuvre providing a single point of contact from conception through 3D pre-visualization, administrative handling, fabrication, and final delivery. Customers are acquired through direct field sales, referrals, and partnerships with architects and building professionals, with no digital advertising or marketplace channel.

The company's technology stack centers on structural steel (charpente métallique) leveraging versatility, recyclability, and economy, supported by in-house design offices, fabrication workshops, and erection teams capable of complex work including collaborating floor beams (planchers collaborants), galvanized/thermolaqued steel structures, structural reinforcement, and adaptation of Haussmann-era buildings with tight tolerances (±2 mm). Notable references include Lycée Darius Milhaud, Hôpital Lariboisière, a 1,550 m² indoor karting building, and 46 Avenue de la Grande Armée in Paris. Revenue, funding, and detailed ownership percentages are not publicly disclosed.
