BEL'M

What BEL'M does

BEL'M designs, manufactures, and markets entrance doors from its headquarters and primary production facility in Machecoul, France. Operating as a brand under SAS CETIH MACHECOUL within the diversified industrial conglomerate Groupe CETIH, the company has built a catalog of more than 300 customizable door models over 40+ years, spanning four material platforms — aluminum (ALU 100/80/60), steel (ACIER 68+/48), wood (BOIS 100 ABSOLU/100/80/60+/50), and mixed aluminum-wood (MIXTE) — plus service doors, garage doors, motorization, and accessories such as aluminum and glass canopies (Zénith, Cité lines). Technical differentiation rests on multi-material manufacturing expertise, thermal-break aluminum profile technology, the proprietary EVO Vitrage glazing system delivering more than 14% improvement in thermal performance, and A2P-certified security locking. A connected motorized lock add-on extends the range into keyless entry for select aluminum, steel, and wood lines.

BEL'M serves primarily individual French residential homeowners and self-builders undertaking new construction or renovation, with a secondary commercial segment ("Grand Trafic") addressing high-traffic retail and public-access buildings via the Urbana aluminum line. End-customer acquisition is driven by an 11-channel marketing mix that combines a corporate website with catalog, e-catalogue, door simulator, and dealer locator, organic social on Facebook, Instagram, Pinterest, YouTube, LinkedIn, and Houzz, plus a dedicated professional portal at belmpro.fr for installer partners.

Revenue is generated exclusively through one-time product sales routed through a B2B network of professional resellers and installers (partenaires revendeurs) across France, with no direct-to-consumer e-commerce, no subscription layer, and no recurring service revenue. Pricing is per-unit and publicly disclosed for standard aluminum configurations (e.g., Urbana entry doors at €1,660-€3,025 HT depending on configuration), with no public enterprise contract or anchor-customer pricing model in evidence. Geographic footprint is single-country — France — with no documented international distribution.
