ROUSSEAU

What ROUSSEAU does

ROUSSEAU SAS is a privately-held French manufacturer of bulk storage solutions in composite materials, founded in 1966 and headquartered in Fenioux, Nouvelle-Aquitaine. The company designs and produces silos, tanks, hoppers and basins (bacs) from fiberglass and polyester resin using a filament-winding production process, with specialist resin systems (orthophthalic, isophthalic, vinylester) selected by application, plus carbon fiber and flax-fiber variants for higher-spec or eco-innovative parts. Capacity ranges from compact 3.5m3 Babystar silos up to 200m3 industrial tanks at 4200mm diameter. Customers are split across Agriculture (animal-feed silos, mineral storage, fertilizer tanks, wine tanks, water tanks), Industry (chemical, water-treatment, heavy, cement, food, energy, road-transport), and Subcontracting (custom composite parts for nautical and leisure OEMs).

Revenue is generated through three motions: (1) sale of composite storage products via a network of more than 100 independent resellers across France and a direct field-sales force for large industrial projects, with custom quote-based pricing and project timelines often running multi-year; (2) custom subcontracting of composite parts (polyester laminate, glass fiber, carbon fiber) for nautical, leisure and transport OEMs through a dedicated facility at Le Busseau in Deux-Sèvres under 20-year partnership relationships; and (3) supporting services and consumables: ROUSSEAU Services (maintenance, installation modification, emergency repair) plus an online E-boutique for spare parts and accessories. Pricing is opaque and quote-driven; products are configured by capacity, diameter, fittings and accessories, with no public price list. Distribution is single-country (France) with limited export exposure via the subcontracting division; international geographic expansion is not yet evident. Patents (Boitard MULTYS 320/700, TIPIG shelter), ATEX and EU 10/2011 compliance, an INPI-registered trademark, and the SiloMetric/FluidMetric sensor sub-brand form the proprietary spine of the offering. Headcount is reported at 46 in firmographics, indicating a small-to-mid-sized industrial operation; share capital is €600,000 and no external investment, M&A or public listing is identified.

Product overview

ROUSSEAU is France's leading manufacturer of bulk storage solutions (silos, tanks, hoppers, and basins) made from fiberglass and polyester resin, operating since 1966. The product portfolio spans three main sectors: Agriculture (silos for animal feed, mineral storage silos, rendering tanks, fertilizer tanks, wine tanks, water tanks, and the Rousseau Metric sensor line including SiloMetric and FluidMetric), Industry (industrial silos in various configurations—on feet, on skirt, on portal, terrace; vertical and horizontal tanks; road tankers; and composite citernes), and Subcontracting (custom composite creations for nautical, leisure, and transport sectors). Key agricultural silo lines include Star, Babystar, Gâtine 320/700, GT/GTN, cloisonné 50/50, and powder milk silos, with innovations such as the patented Boitard Multys 320, Ouv'sol motorisé, and TIPIG pig housing (Innov'Space 2020 award). The company also offers ROUSSEAU Services for maintenance and an e-commerce platform for spare parts and accessories.

Partnerships

Three partnerships are on record, tiered core.

• Spitzer EurovraccoreStrategic or Co-development PartnerDeveloped the 34m3 composite polyester road tanker during the 2010s in cooperation with Spitzer Eurovrac. This is a major innovation in the liquid road transport sector. ROUSSEAU manufactures the composite tank body while Spitzer provides the vehicle chassis and commercializes the complete solution. Rousseau's composite tanks offer advantages over aluminum (thermal insulation, lower product retention, easier cleaning, long-term durability).
• Over 100 French ResellerscoreChannel Partner/ Reseller/ DistributorROUSSEAU distributes its products through a network of over 100 independent resellers located across France. These resellers provide local sales, distribution, and customer service for Rousseau's complete range of storage solutions.
• Various Nautical and Leisure ManufacturerscoreStrategic or Co-development PartnerFor 20 years, ROUSSEAU has maintained partnerships with prestigious companies in the boat building (construction navale) and leisure sectors for custom composite part manufacturing. Activities include technology transfer, joint development, and export projects. These partnerships are managed through Rousseau's dedicated facility at Le Busseau in Deux-Sevres.
