What Sidenor Aceros Especiales does

Sidenor Aceros Especiales S.L. is a privately held Spanish producer of special steel long products, headquartered in Basauri (Basque Country) and operating one of Europe's largest dedicated special-steel manufacturing centers with annual capacity exceeding 900,000 tonnes. Production is structured around Electric Arc Furnace (EAF) melting with 97% recycled scrap input, supported by seven plants across the Basque Country, Cantabria and Catalonia (Basauri, Reinosa, Azkoitia, Polinyà, Legutiano, Vitoria-Gasteiz, Sagunto) plus marine-, forging- and bright-steel finishing specializations, and by an extensive portfolio covering carbon, alloy, microalloyed, bearing, tool and stainless grades in semi-finished (billets, blooms), rolled (wire rod, bars, flats), drawn/turned/ground bright bars, drawn wire, and forged forms. The company is differentiated by its proprietary sideCO2 software (LCA calculation for 20,000+ references), the innobars premium innovation brand, 50+ R&D engineers and 30+ years of metallurgical expertise, and a portfolio of certifications including IATF 16949, ISO 9001/14001/45001/50001/27001/20400, TISAX and major marine classifications (ABS, DNV, Lloyd's, BV, NKK, CCS).

Sidenor sells primarily through direct enterprise B2B channels, with commercial delegations in Germany, France, Italy and the United Kingdom serving customers across automotive OEMs and Tier-1 suppliers, heavy vehicles, wind energy, oil & gas, off-highway machinery, and industrial infrastructure (shipbuilding, civil construction, defense, railway, petrochemical). Named automotive customers include Volkswagen, Renault, PSA/Stellantis, BMW, Daimler/Mercedes-Benz, Ford, Fiat and Honda. The revenue model combines hardware sales of steel long products (quote-based pricing indexed to grade, dimensions, treatment, volume, with carbon-footprint-adjusted pricing for sustainable ranges) and a lower-margin technical-assistance service line providing pre- and post-sale metallurgical, thermal-treatment and process-optimization support.

Strategically, the company is repositioning around validated decarbonization: SBTi-approved 1.5°C-aligned targets, CDP B rating, a 65% CO2 reduction since 2005 targeting 61.5% Scope 1+2 by 2033, 100% renewable electricity from 2025, 90% waste valorization, and active industrial trials with green hydrogen and biomass/biocarbon routes via partnerships such as H-ACERO2, 1S2H4C and GreenHeatEAF. Recent milestones include the 2018 acquisition of Grup Capresa, the 2024 SBTi validation, 2025 first green-hydrogen industrial tests, and a growing line of carbon-neutral steel grades commercialized through sideCO2 and the innobars brand.
