ACSO

What ACSO does

ACSO is an integrated Brazilian steel service center headquartered in Curitiba, Paraná, operating from a 50,000 m² manufacturing facility with stated annual processing capacity of 240,000 tonnes of flat and long steels. Founded approximately three decades ago, the company sources steel from certified mills and runs an in-house processing stack that includes CNC precision drilling, laser/plasma/oxycutting, automated straight and angular cutting, blanking, bending, welding, shot blasting, and primer application. Its product catalog spans seven core categories — coils, plates/sheets, cold-formed structural profiles (Perfis Dobrados), welded profiles (Perfil Soldados), W-beams, solar mounting structures, and engineered Special Projects — complemented by two processing service lines for flat steels and long steels. The business model is direct, quote-based sales targeting industrial buyers across thirteen verticals including automotive, civil construction, metal construction, energy (including renewables), agricultural and road implements, industrial machinery, white goods, furniture, naval, and oil and gas. ACSO holds ISO 9001:2015 certification, employs automotive-grade quality tools (APQP, FMEA, PPAP, PCP, 8D), and claims national coverage across Brazil from its Curitiba hub, with a secondary operational site in Barra do Piraí.

The company is privately held with no disclosed parent, no external investors, and no funding history in the source data. Revenue is not publicly disclosed and the formal headcount range (11–50) is materially below what would be expected for a facility of this scale, indicating the figure likely reflects corporate rather than plant workforce. The most visible commercial relationship is with CBTU (Companhia Brasileira de Trens Urbanos), for which ACSO has executed multiple railway track supply and unloading projects in 2025 to support Brazil's Northeastern rail network. Management is led by a long-tenured Financial Director (Luciana Andrade, ~30 years at Grupo Aços), reflecting stable ownership and continuity rather than recent leadership turnover.

Core offering

ACSO is an integrated steel service center based in Curitiba, Brazil, operating a 50,000 m² manufacturing facility with capacity to process up to 240,000 tonnes of steel per year. The company distributes and processes flat and long steel products (coils, sheets, folded and welded profiles, W-beams, and renewable energy structures) and provides integrated processing services including cutting, bending, drilling, welding, thermal cutting (laser, plasma, oxycutting), and finishing (shot blasting, primer application). It serves industrial customers across automotive, construction, energy, and manufacturing sectors throughout Brazil.

Product overview

ACSO is an integrated steel service center for flat steels (Aços Planos) and long steels (Aços Longos), based in Curitiba, Brazil. The company operates a 50,000 m² manufacturing facility with capacity to process up to 240,000 tonnes of steel per year. Its product portfolio centers on seven core steel product categories: Bobinas (coils in hot-rolled, cold-rolled, galvanized, and xadrez varieties), Chapas (plates/sheets), Perfis Dobrados (cold-formed structural profiles), Perfil Soldados (welded structural profiles), Vigas W (W-beams), Soluções para Energia Renovável (renewable energy structures), and Projetos Especiais (custom high-complexity projects). These products are complemented by two service lines — Serviços para Aços Planos (flat steel processing: slitting, cutting, thermal cutting, blanking) and Serviços para Aços Longos (long steel processing: drilling, cutting, marking, shot-blasting, priming) — enabling ACSO to provide complete solutions from raw material supply through custom fabrication for diverse industrial segments.
