Groupe Acoma

What Groupe Acoma does

Groupe Acoma is a private industrial group founded in 1979 and headquartered in Martinique (legal entity Acoma Services, led by Director General Michel Bellemare). It specializes in steel transformation, producing reinforcement steel (armatures) for reinforced concrete and metal building envelopes (roofing and cladding) under established brands including Biométal, Trefima, and TOP. The group operates 12 subsidiaries across six territories — Martinique, Guadeloupe, French Guiana, La Réunion, and the Grand Ouest of metropolitan France — supported by 350+ employees and 60,000 tonnes of annual production capacity.

The business serves construction professionals, building-material distributors, individual self-builders, and public-sector infrastructure clients. Notable project references include the Lycée Schoelcher, a Pôle universitaire de santé, and EHPAD facilities. Technical credentials include AFCAB certification and seismic-resistant certification for reinforcement products in Caribbean construction. In 2023, the group launched the first robotic production line in the French Antilles to automate fabrication, and in the same year opened a new Top Caraïbes factory and experiential showroom.

Groupe Acoma generates revenue through the manufacture and sale of finished steel reinforcement products and metal envelope systems to a mix of B2B professional channels, retail/DIY customers, and project-based public contracts. Distribution advantages derive from local production in import-dependent island territories, while growth has been driven by territorial expansion (notably La Réunion in 2013, Top Martinique and Top Amazonie in 2016, SIA in 2015) and selective acquisitions (Top Caraïbes in 2024).

Core offering

Groupe Acoma is a French industrial group that transforms steel into reinforcement products and metal building envelope solutions. The company designs, manufactures, and distributes standard and custom reinforcement steel (armatures) for concrete construction, as well as profiled metal roofing, cladding, and structural components for building envelopes. Its products are certified to seismic-resistance standards and are produced through AFCAB-certified processes serving construction professionals and infrastructure projects across French overseas territories and mainland France.

Product overview

Groupe Acoma is an industrial group specializing in steel transformation, operating 12 subsidiaries across 6 territories (Martinique, Guadeloupe, French Guiana, La Réunion, and Grand Ouest France). The product portfolio is organized around three core offerings: (1) Standard steel reinforcement for concrete (armatures standard) produced by Trefima Martinique and Trefima Guadeloupe; (2) Custom steel reinforcement (armatures sur-mesure) produced by SIA/EMPA and Biométal Guyane; and (3) Metal building envelope solutions (enveloppe métallique du bâtiment) — profiled roofing and cladding sheets, facade blades, and accessories — produced under the TOP, BIOMETAL, SPO/Arteface, and Trefima brands. The subsidiaries operate with substantial autonomy while benefiting from shared Group expertise in manufacturing processes, quality control, and innovation.

Direct peers

• Commercial Metals Company: Commercial Metals Company manufactures and fabricates rebar and related construction-steel products. It is comparable to Acoma's concrete-reinforcement operations, including standard and project-specific fabrication, but focuses primarily on North America.
• Joris Ide: Joris Ide manufactures metal roofing, cladding, insulated panels, and related building-envelope solutions. It directly overlaps with Acoma's profiled steel roofing and facade business and serves a similar construction customer base.
• CELSA Group: CELSA Group is an integrated steel group with long products, rebar, wire, and reinforcement mesh. These products and its construction-market exposure are directly comparable to Trefima and SIA within Groupe Acoma.
• Kingspan: Kingspan is a global building-envelope specialist offering insulated panels, metal roofing, and facade systems. It is a direct product peer for Acoma's roofing, cladding, and accessory portfolio, although it is considerably larger and broader.
• Van Merksteijn: Van Merksteijn manufactures steel reinforcement products including rebar, wire, and welded mesh. It is a direct peer for Acoma's reinforcement bars, welded mesh, and wire-drawing activities.
• Riva Group: Riva Group produces long steel products including rebar and wire rod and operates steel transformation facilities. It is closely comparable to Acoma's standard and custom concrete-reinforcement operations, though at much greater production scale.

Broad incumbents

• Marcegaglia: Marcegaglia is a large steel processor and construction supplier with products including roofing, cladding, and fabricated metal. It overlaps with Acoma's sheet profiling and building-envelope portfolio while also operating across many steel categories.
• ArcelorMittal: ArcelorMittal is a global steel producer with construction-related reinforcement steel and building-envelope offerings, including through ArcelorMittal Construction. It is comparable to Acoma across both reinforcement and metal-building products, but at substantially greater scale and geographic reach.
• NLMK: NLMK is a global steel producer with long-product and reinforcement-steel exposure serving construction markets. It is a broad incumbent comparable to Acoma's reinforcing-steel manufacturing, although less directly overlapping with its local sheet-metal envelope operations.
• Tata Steel: Tata Steel supplies construction steel, reinforcement products, and building systems. Its combination of rebar and building-envelope offerings is comparable to Acoma's two core product pillars, but Tata Steel is integrated and globally scaled.
