Altimexor Metal
Altimexor Metal
Engineered for high tensile capacity, structural flexibility, and superior corrosion resistance in West African maritime and lagoon environments.
The global steel channel industry is undergoing a structural transition driven by advancements in low-carbon steelmaking, high-strength low-alloy (HSLA) metallurgy, and modular off-site fabrication methodologies. As urban environments across West Africa experience dynamic economic expansion, structural channels—specifically C-channels, U-profiles, and Parallel Flange Channels (PFC)—have emerged as indispensable elements in structural framing, bridge trusses, industrial warehouses, and coastal foundation works.
In Benin, particularly within the political capital of Porto-Novo and its surrounding metropolitan corridor connecting to Cotonou, rapid municipal modernizations, port expansions, and agricultural storage facility developments demand structural steel components capable of exhibiting extreme mechanical reliability under tropical, high-humidity, and saline atmospheric conditions.
Porto-Novo's microclimate, influenced by Lake Nokoué and proximity to the Atlantic Gulf of Guinea, subjects structural steel to corrosive C4/C5 atmospheric classifications. Our channel sections feature thick hot-dip galvanization (HDG) per ISO 1461, preventing localized pitting and stress-corrosion cracking.
The expansion of agricultural logistics hubs along the Ouémé Department requires structural frames with high strength-to-weight ratios. Cold-formed C-channels and hot-rolled U-beams offer precise dimensional tolerances for rapid bolting and field assembly.
Soft alluvial soils surrounding Porto-Novo's riverine channels demand robust retaining wall structures. Deep-flange G300/G350 PFC steel channels coupled with timber or composite panels provide reliable ground stabilization for civil developments.
From municipal administrative buildings to overhead crane girders, our low-carbon steel profiles (Q345B / S355JR) ensure superior moment-resisting capacity and fatigue resistance under high dynamic loads.

All bulk steel shipments destined for Porto-Novo are routed via the autonomous Port of Cotonou (PAC). Our logistics team arranges direct transshipment via the RNIE1 arterial highway, delivering steel profile bundles straight to construction sites in Porto-Novo within 48 hours of port customs discharge.
To combat maritime moisture during ocean transit across Atlantic shipping routes, channel sections are bundled with heavy-duty steel strapping, waterproof plastic wraps, anti-corrosion VCI coatings, and wooden dunnage for damage-free forklift unloading.
We provide comprehensive pre-shipment inspections certified by independent third-party agencies such as SGS, Bureau Veritas, or Intertek, guaranteeing compliance with Benin's national standards (ECAMOC/SONCAP certifications).
Browse our full range of structural C-channels, U-bars, PFC profiles, and custom roll-formed shapes.
Transitioning production towards Electric Arc Furnace (EAF) steelmaking utilizing recycled scrap. This process significantly lowers embedded carbon emissions, providing environmentally certified structural steel for eco-conscious development projects in Benin.
Combining thermal spray zinc-aluminum coatings with architectural-grade polyurethane topcoats to extend the service life of coastal structural steel up to 50 years with minimal maintenance in humid lagoon environments.
Developing ultra-high-strength steel grades (S460J2 / S500Q) in C and U profile geometries to reduce total structural weight by 20–30%, lowering overall freight logistics costs for West African import projects.
Standard manufacturing lead times range between 15 to 25 days depending on section dimensions and coating requirements. Ocean freight from main Chinese ports (Shandong/Tianjin/Ningbo) to Cotonou Port typically takes 30 to 35 days, followed by 2–3 days for customs clearance and road transport to Porto-Novo.
For structures near high humidity and salt air (Lake Nokoué/Porto-Novo lagoon), Hot-Dip Galvanizing (HDG) per ISO 1461 with a minimum coating thickness of 85 μm is highly recommended. For industrial plants, a epoxy-polyurethane duplex paint system over hot-dip galvanized steel offers maximum long-term barrier protection.
