SIMONIN

What SIMONIN does

SIMONIN SAS is a French specialty timber engineering firm headquartered in Montlebon, France, founded in 1967 and operating as a subsidiary of the Ateliers De France Group. The company designs, manufactures, and installs bespoke glued laminated timber (glulam), cross-laminated timber (CLT), and hybrid timber-steel/timber-concrete structures for architecturally ambitious projects, alongside a portfolio of standardized wood components (cladding, insulation panels, floor and partition systems). Its core proprietary technologies include Résix® (patented steel-rod and epoxy assembly system), Sapisol® (insulating sandwich panel), and RECOBOIS (in-house AI-powered wood defect sorting system trained on 5,000+ images). Operations are vertically integrated across 23 trades with 150+ employees, three design offices, four CNC machining centres, and a 20,000 m² production facility on 8 hectares.

SIMONIN serves enterprise B2B clients — primarily architects, project owners, construction companies, and general contractors — through a direct field sales model. Revenue is generated through bespoke project contracts (villas, multi-story residential towers, sports facilities, footbridges, exhibition pavilions, commercial hubs) with quote-based pricing determined via feasibility studies and quantity take-offs, supplemented by sales of standardized components to distributors and specifiers. The customer base is international, with a dedicated International department managing projects across Europe, South America, the Middle East, and Africa; landmark references include the French Pavilion at Milan Expo 2015, Villa Carmelha in Monaco, two Paris 2024 Olympic structures, and the LEED-certified Zona Franca del Plata in Uruguay.

The business model combines custom-engineered project delivery with recurring product sales and installation support services. SIMONIN is employee-owned since 2009, operates under a SASU legal structure, holds multiple ATec technical approvals and CE/CTB/FSC/PEFC certifications, and is part of the broader Ateliers De France Group (€850M revenue, 56 companies, 3,000+ employees, 12 countries). Distribution is exclusively direct, with no resellers or marketplace channels for custom structures, and 100% of production is located in France.
