Stahlberg

What Stahlberg does

Stahlberg GmbH is a German specialty supplier of industrial C-parts, founded in April 1996 in Langenfeld, Germany. The company manufactures and distributes high-quality connection elements, including special screws, nuts, standardized fasteners (DIN, ISO, EN, ANSI, ASME, ASTM), and complex turned and milled parts ranging from small threaded pins (M2x4) to large parts exceeding 3,000mm in length and 4 tons in weight. Its product portfolio also includes parts manufactured from special materials (nickel alloys, duplex/superduplex steels, titanium, tungsten, cobalt, copper, aluminum alloys) and a range of surface refinement services (galvanic, enamel, PVD/CVD, hardfacing, nitriding, inductive/laser/flame hardening). Since 2017, Stahlberg has supplemented its 1,500+ supplier network with an in-house production facility acquired to shorten delivery times.

The company operates a 360-degree service model combining consulting, manufacturing, warehousing, quality assurance, and delivery from a single source. Over 800 tons of special steel are held in climate-controlled warehouses, enabling just-in-time delivery via an in-house fleet to customers in Germany, Europe, the USA, Canada, and selectively across Asia. In-house quality assurance uses OES and XRF spectrometers, two FARO measuring arms with sub-0.018mm accuracy, approximately 700 hand-held measuring devices, and certified dye penetrant testing, supported by lifetime-archived quality documentation that enables traceability of every part back to the melting process. The company has held DIN EN ISO 9001 certification continuously since 2001, currently ISO 9001:2015.

Go-to-market is direct sales-led: Stahlberg consults customers on material selection, coatings, and production planning, then coordinates complex multi-supplier orders with its own QA and logistics overlay. Pricing is custom quote-based, tied to specifications, materials, certifications, and delivery terms. The customer base is concentrated in industrial manufacturers and engineering firms, with a long-standing framework contract with Siemens AG Energy dating from July 2000 and historical international deliveries to Siemens operations in the USA and Asia. The company is privately held, classified as a German Mittelstand (KMU) enterprise with 11-50 employees, and is led by Managing Director Furat Koudsi following the 2015 generational handover from founder Rainer Stahlberg.
