What ALTEMA groupe does

ALTEMA groupe is a French manufacturer and distributor of metal solutions serving the building envelope and chimney smoke-evacuation trades. The group operates two industrial business lines — HILDEM for multi-metal building cladding (zinc, aluminum, steel, copper, stainless steel, lead, plus proprietary raw-material sub-brands HFXCOOL, ALUCOLOR, ZNPRO and the retrideX EPDM waterproofing membrane) and MODINOX for insulated chimney conduits and smoke-evacuation systems — together with a complementary portfolio of distributed third-party brands (Invicta, JC Bordelet, De Dietrich, Velux, VMZinc, etc.). Production runs through three French sites using laser welding and cutting, CNC punching, robotic bending, rolling and forming, with an in-house combustion laboratory for certification. The most recent innovation signals include the Alucolor Flex 2026 colored-aluminum catalogue and the retrideX flat-roof waterproofing line.

The business is monetized across multiple one-time revenue streams: sale of branded and distributed metal construction products, fee-bearing custom bending/forming services (24 ateliers and 33 stations embedded in agencies), logistics and delivery (3 central/regional platforms, click & collect), and professional training fees via ALTEMA'CADEMY. B2B pricing is non-public and routed through a professional portal accessible to accredited trade buyers. Go-to-market combines a sales-led field force across 40 agencies, a self-serve digital portal, channel partnerships with leading European cladding and stove brands, and a content marketing engine (catalogues, newsletter, corporate videos). Customer segments are deliberately broad across use case (single-family housing, multi-family residential, tertiary buildings, industrial buildings and protected heritage) but heavily skewed to SMB installers (roofers, zinc-workers, heating engineers, stove fitters) across France.

As of 2024–2025 the group, privately held by Chequers Capital since 2016 and led by President Didier Namy, employs more than 600 people across all 13 French mainland regions plus Corsica, traces its origins to the 1869 HILD family business in Alsace, and is executing the CAP 160 strategic program toward its 2029 anniversary. Operating posture is active; certifications include ISO 14001 (environmental) and ISO 45001 (occupational health and safety), with reported sector-leading workplace safety metrics and a 63% NPS promoter share.
