Atelier Jouannet

What Atelier Jouannet does

Atelier Jouannet is a privately held French metalworking and structural steel company founded in 1964 and headquartered in Boos, near Rouen in Normandy. Operating as a SAS (Société par Actions Simplifiée) with a team of approximately 8-10 specialized artisans, the firm delivers custom metalwork (described as "métallerie de haute couture") to building professionals, project owners (donneurs d'ordres), and individual clients across the Seine-Maritime and Eure departments. Its offering spans five activity domains: structural steel framing (charpente métallique) for buildings up to 1,000m², fine metalwork including architectural staircases and safety railings compliant with ERP standards, roofing and cladding (couverture/bardage), custom steel and aluminum joinery (menuiserie), and high-precision laser cutting with CNC numerical bending. The firm holds four QUALIBAT certifications (2411, 2811, 4413 at Technicité supérieure, 4421) and collaborates with specialized engineering firms (bureaux d'études) for structural calculations compliant with Eurocodes and DTU standards. In-house numerical machinery supports fabrication across mild steel, stainless steel, aluminum, brass, and copper.

The company generates revenue through two principal streams: project-based custom metalwork services priced via quote (steel structures, fine metalwork, roofing, cladding, and joinery), and direct e-commerce sales of standardized custom aluminum air conditioner covers (Cache Climatiseur sur Mesure) priced from €259 (XS) to €439 (L/XL) with nationwide France delivery in approximately 20 business days. The go-to-market motion is primarily sales-led and direct, with field engagement for custom projects in Normandy, complemented by an online product configurator for the standardized product line. Marketing is conducted through the company website (portfolio, testimonials, quote form), Instagram, Facebook, and LinkedIn, with named reference customers including DANIMO (retail), TRADIVINS (wine/spirits distribution), and MAD CREATION (interior design).
