What Interfer does
Interfer Edelstahl Handelsgesellschaft mbH is a privately held German steel trading group headquartered in Karlsruhe and founded in 1986. The company operates as a B2B wholesale distributor of steel products and integrated trading services, sourcing steel bars, wire rods, flat products, ferroalloys, graphite electrodes, and raw materials for steel production from global producers and delivering them to industrial manufacturers across more than 80 countries. Interfer is positioned as one of the most important importers of steel bars to Europe and serves at least eight primary industrial verticals, including mechanical processing, machinery construction, automotive, energy production, ship construction, oil and gas, tool construction, and steel mills. The group operates through 9 locations across 7 countries — Germany, Austria, Czech Republic, the United States, Italy, the United Kingdom, and China — plus an agent network covering Spain, Portugal, and France.
The company's core business model is transaction-based steel trading: revenue is generated from negotiated, quote-by-quote pricing on individual international trades, supplemented by a vertically integrated service stack that includes sourcing and quality control, global logistics and multi-location warehousing with EDI/API connectivity, customs and CBAM compliance management, and credit-insurance-backed trade financing that allows customers to pay after receipt of goods. The group is wholly owned by Managing Director Gerold Lorenz, who became sole shareholder in 2020, and reports consolidated revenue of €373 million for fiscal year 2024/2025 across 51-100 employees. Recent strategic positioning emphasizes a CO2-reduced Green Steel portfolio (enabled by a 2024 offtake agreement with Meranti Green Steel's planned HBI plant in Oman), CBAM declarant services, and a 42% absolute GHG reduction target by 2030.

Interfer competitors and assessment
Company assessmentRegional players
- Marubeni-Itochu Steel Inc. (MISI): Japanese-headquartered steel distributor and processor with extensive Asia-Pacific footprint and limited European presence. Comparable in business model of intermediating mill output to industrial customers; differs geographically from Interfer's Europe-centric base.
- Metal One Corporation: Japan-based steel and metal products trading company jointly owned by Mitsubishi and Sojitz. Comparable to Interfer as a global steel trader with mill relationships and downstream distribution; operates primarily in Asia vs. Interfer's European core.
Broad incumbents
- Tata Steel Nederland: Dutch arm of Tata Steel with significant steel and flat-product distribution into Western European industrial markets. Competes with Interfer for long and flat product customers in the same end-markets (automotive, construction, machinery).
- thyssenkrupp Materials Services: The distribution arm of thyssenkrupp, one of the largest materials distribution networks in Europe and North America for steel, stainless, and aluminum. Interfer already partners with thyssenkrupp Materials Trading on the Meranti HBI project, evidencing direct overlap in steel distribution channels.
- ArcelorMittal: World's largest steel producer with its own distribution and trading operations reaching European industrial customers directly. Sets pricing reference and competitive benchmark across long and flat products that Interfer trades.
- Salzgitter AG: One of Europe's largest steel producers with integrated trading and processing units serving automotive, construction, and tube markets. Operates a parallel distribution/trading proposition to Interfer, though at significantly larger scale and with primary production exposure.
- Voestalpine AG: Austrian integrated steel and technology group with a Global Commodity Trading division distributing steel and metal products across Europe and overseas. Overlaps with Interfer in Austria-based presence and continental European customer base.
Direct peers
- Stemcor Global Holdings: London-headquartered international steel trading company intermediating between mills and end-users in flat and long products globally. Closely mirrors Interfer's model of cross-border steel intermediation, product breadth, and reliance on logistics/warehousing.
- Klöckner & Co SE: Frankfurt-listed German steel and metal distribution group operating a multi-million-tonne distribution and processing network across Europe and the Americas. Directly comparable to Interfer as a steel/metal wholesale distributor serving industrial end-markets with added services.
- Duferco International Trading Holding: Swiss-based global steel and raw materials trader with offices across Europe, Asia, and the Americas. Comparable in product portfolio (long products, flat, raw materials), distribution model, and reliance on international trade flows.
