Stahlwerk Thuringen

What Stahlwerk Thuringen does

Stahlwerk Thüringen GmbH is a German long-profile steel manufacturer headquartered at Kronacher Straße 6, Unterwellenborn, near Saalfeld in Thuringia. The firm operates a modern electric arc furnace (EAF) mill that converts scrap metal into hot-rolled structural profile steel, with primary raw inputs sourced within a 300 km regional radius to support circular-economy and lower-carbon production. Its delivery program covers European standard profiles (IPE, HE, HP/HD, UPN, UPE), British/international profiles (UB/UC/UBP/PFC), North American ASTM A6 and Japanese JIS profiles, steel railway sleeper profiles, and specialty grade 16Mo3 for high-temperature applications. A dedicated sub-brand, GREEN STEEL, markets the same output with a climate-friendly positioning.

The business model is B2B and transaction-based: the company sells profile steel in bulk to an international network of steel traders and authorized sales agencies, with order intake processed through a customer portal and direct sales representatives. Distribution spans more than 60 countries, supported by a multilingual website (German, English, French, Portuguese) and an active presence on LinkedIn, Xing, YouTube, Facebook, and Instagram, plus industry-event participation. Pricing is quote-based and negotiated per order rather than publicly disclosed.

Stahlwerk Thüringen is a wholly-owned subsidiary of CSN – Companhia Siderúrgica Nacional, a publicly traded Brazilian steel conglomerate, providing financial backing and international connectivity. Headcount is reported at 501-1,000 employees, and the firm operates a single primary production facility. Founded in 1872, the company describes itself as combining traditional heavy-industry heritage with a sustainability-led modern positioning, though no financial revenue figure is disclosed in the available data.

Direct peers

• SSAB: Swedish steelmaker that has pioneered EAF-based fossil-free steel production with its HYBRIT initiative. Comparable to SWT through EAF/scrap-based technology platform and green-steel brand positioning targeting low-carbon premium markets.
• Dillinger: German heavy plate producer serving construction, linepipe, and engineering markets. Comparable to SWT through German steel production heritage and specialized structural/engineering steel applications, though focused on plate rather than long profiles.
• Salzgitter AG: German steel and tubes producer operating EAF and integrated routes, manufacturing structural and tube products for European construction and industrial customers. Closely comparable to SWT as a German EAF-based structural steel producer serving similar European end-markets.
• Riva Group: Italian family-owned EAF-based long products producer manufacturing structural sections, beams, and merchant bars for European markets. Comparable to SWT through EAF-based profile steel production and mid-sized European mill footprint.

Broad incumbents

• Thyssenkrupp Steel Europe: Major German steel producer of flat and stainless products with a planned transition to EAF/DRI green steel. Comparable to SWT in German steel heritage and structural steel markets, though with a more diversified product mix and integrated legacy footprint.
• Tata Steel Netherlands (formerly HKS): Dutch/German-based steelmaker (part of Tata Steel group) producing strip, plate, and structural products for European construction markets. Comparable as a European structural steel supplier with an active green transition roadmap, though larger and more diversified than SWT.
• ArcelorMittal: World's largest steelmaker with European operations producing structural profiles, plate, and other long products across multiple sites. Overlaps with SWT in structural profile categories but operates at significantly larger scale with a diversified product portfolio.
• NLMK (Novolipetsk Steel): Russian-owned flat and long products steelmaker with European distribution (NLMK Europe/La Louvière). Overlaps with SWT in European structural steel distribution channels, though primarily a flat-products player at the parent level.
• voestalpine: Austrian steelmaker with EAF-based long products division (Donawitz) producing sections and specialty steels. Comparable to SWT in European structural steel manufacturing and decarbonization roadmap, but with a broader product portfolio including automotive and railway systems.

Emerging players

• Metinvest: Ukrainian vertically integrated steelmaker producing pig iron, slabs, and long products including sections, with European trading presence. Comparable to SWT through EAF-based long products and trader-channel distribution, though with a different regional footprint.
