Primetals Technologies Limited
Primetals Technologies designs, builds, and services metallurgical plants across the entire steel value chain, from raw materials to finished product. The company was formed from the merger of Siemens Metals Technologies, Mitsubishi-Hitachi Metals Machinery, and several other legacy engineering businesses. It operates as a full-line supplier with expertise in agglomeration, ironmaking, steelmaking, continuous casting, endless casting and rolling, hot and cold rolling, strip processing, and automation and digitalization. The firm deploys capital through engineering, procurement, and construction contracts for new plants, as well as modernization and upgrade projects for existing mills. It has a major focus on green steel—low-carbon production technologies including direct reduced iron plants and electric arc furnaces. Primetals' solutions cover energy efficiency, productivity improvement, raw material flexibility, product quality, and data intelligence. It has active projects across China, Vietnam, Austria, and Germany, and partners with global steelmakers such as Dillinger, ROGESA, voestalpine, and Rizhao Steel. Primetals does not disclose its AUM or ownership structure. The engineering group employs a large professional workforce spread across offices in Menlo Park, London, Greenwich, Auckland, Houston, Barcelona, Chicago, Geneva, Hoofddorp, and Ludwigshafen. In May 2026, the firm started up the world's most powerful Arvedi ESP plant at Zhongshou Special Steel in China, and upgraded a 5-strand bloom caster for bearing and spring steel production in China. It also signed a major greenfield project with VinMetal in Vietnam for long and flat steel lines. A key structural differentiator is Primetals’ position as a pure industrial technology supplier rather than a capital allocator or family office. Its business model centers on engineering and construction contracts, not investment returns. The firm maintains a wide geographic footprint and a large base of recurring service and upgrade revenue, which gives it a stable, operational posture distinct from asset managers or family offices.
