What Castel & Fromaget does

Castel & Fromaget is a French metal building constructor headquartered in Fleurance (Gers), operating as a wholly-owned subsidiary of the FAYAT Group within its FAYAT Métal division. Founded in 1927, the company designs, fabricates, and installs structural steel and aluminum buildings, integrating peripheral trades — roofing, facade, locksmithing, metalwork, and aluminum joinery — to deliver turnkey envelopes as a single "ensemblier du métal" contractor. It holds rare certification 2414 (exceptional technicality) and CE marking EXC4, and runs two industrial sites at Fleurance and Monteils with combined annual steel production capacity of 10,100 tonnes, equipped with 5000W laser cutting, PRS bench, Kaltenbach drilling, and 200T cambreuse machinery.

The company markets itself as the leading French metal building constructor, with a reference portfolio that includes the Airbus A380 Final Assembly Hall at Toulouse-Blagnac (12,000T, 60,000m²), the Canopée des Halles in Paris (7,200T, 92m span, European Excellence Award 2015), the Villa Méditerranée in Marseille (largest inhabited cantilever in Europe), and the Mémorial ACTe in Guadeloupe inaugurated by President Hollande. Beyond these landmark projects, it serves industrial, aerospace, retail, government, and agricultural clients through wholly-owned regional subsidiaries across metropolitan France (Aquitaine, Midi-Pyrénées, PACA, Export) and French overseas territories (Guadeloupe, Guyane, Martinique, Réunion/Mayotte, Saint-Martin/Saint-Barthélemy).

Revenue is generated on a project-by-project, quote-based B2B basis with no recurring component: clients are enterprises and government entities acquired through direct sales, public tenders, and the website contact form. A Services division launched in 2015 adds renovation, asbestos removal, structural reinforcement, and maintenance work on existing buildings, opening a recurring aftermarket. Pre-engineered product lines (Gamme 10 with 10% slope and Gamme 26 with 26% slope) target cost-optimized agricultural and light-industrial buyers, while the Grands Projets activity covers single structures above 5,000 tonnes. Go-to-market is enterprise field sales with no reseller or marketplace channels.
