What Südstahl GmbH & Co. KG does

Südstahl GmbH & Co. KG is a family-owned German steel processing specialist founded in 1946 and headquartered in Mertingen, Bavaria, with a second production site in Aindling acquired through the 2012 Tristahl insolvency purchase and merged in 2014. The company operates an integrated, single-source fabrication model spanning sheet metal cutting (Trumpf TruLaser 3030 laser, Kjellberg plasma with 50-degree bevel capability, NC-controlled oxy-fuel), CNC machining (SHW UFZ6 with 12m x-axis, DMG MORI DMU 60 monoBLOCK, Correa Norma 35, EMCO Powermill), certified welding (MAG, TIG, stud, Merkle Deep Arc), surface treatment, and complete assembly, supported by a 2,000+ ton sheet metal inventory. Quality and access to regulated markets are anchored by ISO 9001:2015, DIN EN 1090-2/3 EXC 3, DIN EN 15085-2 CL1 (rail vehicle welding), DIN EN ISO 3834-2, and DIN EN ISO 9712 Level 2 NDT certifications.

The business serves plant engineering, machinery manufacturing, tool and fixture construction, and rail vehicle industries, with named enterprise customers including Volkswagen, Audi, KUKA, Siemens Transportation Systems, Pfeifer Seil- und Hebetechnik, and ITER, alongside approximately 400 regional SME customers. Revenue is generated through project-based, quote-driven B2B contracts priced on specifications, materials, and complexity, with FY2018 revenue of over €18 million reported by management. The company also manufactures storage systems (Paternoster lifts, conveyors, racking) and operates direct enterprise field sales across the DACH region with international project execution capability. Ownership remains with the Käuferle family under a GmbH & Co. KG structure, with Werner Käuferle and Ulrich Käuferle serving as co-managing directors and no institutional investor capital disclosed.
