M + Materials

What M + Materials does

M+ Matériaux (legal entity M+ Matériaux SAS) is a regional construction materials distributor headquartered in Claira, Pyrénées-Orientales, France, operating as a wholly-owned subsidiary of Groupe Samse, a diversified French building products distribution conglomerate with 27 brands and more than 360 points of sale nationally. The company was founded in 1996 and serves the quart sud-ouest of France through a network of 63+ physical retail branches spanning 14 departments. Its offering comprises over 100,000 product references organized across 10 categories — public works and sanitation, structural materials, plaster and insulation, carpentry and roofing, wood and panels, joinery, floor and wall coverings, electrical/plumbing/heating, terrace and garden, and tools/hardware/safety — delivered through both branch sales and an account-based online catalog with quote-request functionality.

The business is structured around four specialist sub-brands — MPPI (plasterboard, ceiling and insulation), Caréo (tiling and floor coverings), Ménéo (windows, doors and shutters), and MCCE (carpentry, roofing and waterproofing) — plus Socobois, each with dedicated catalogs, product ranges, and trade-specialist teams. This multi-specialist positioning differentiates M+ Matériaux from generic builders' merchants by providing trade-specific expertise alongside generalist inventory. The company's core technology is not proprietary software or AI but rather the integrated branch network, logistics, and purchasing scale inherited from the Samse group, which functions as the operational backbone.

M+ Matériaux generates revenue through hardware sales of construction materials to three customer segments: building professionals (primary), local authorities and public-sector entities, and individual consumers. Pricing is not publicly disclosed; customers must create an account or submit a quote request to access pricing, indicating account-based and project-based commercial terms rather than fixed retail pricing. Services including delivery, equipment rental, waste take-back, and in-branch or on-site consultation supplement the core materials supply model. Philippe Thomas serves as Président and Directeur de la publication per the legal notices, and the entity is registered as a privately held SAS (Société par Actions Simplifiée) under RCS Perpignan 480 211 671.
