More about us

Primetals Technologies was founded on January 7, 2015, as a joint venture of Siemens, Mitsubishi Heavy Industries, and partners. Our company’s solutions are based on over 60 years of innovation in the field of metals production. Both of our predecessor enterprises, Mitsubishi-Hitachi Metals Machinery and Siemens VAI, have contributed greatly to the comprehensive, state-of-the-art portfolio that our company proudly has at its disposal. In early 2020, full ownership of Primetals Technologies was transferred to Mitsubishi Heavy Industries and partners. As a globally active steel-plant builder, Primetals Technologies continues to pioneer the future of metals.

The R&D efforts that Primetals Technologies makes today are a direct continuation of the company’s technological legacy. While our engineers are working tirelessly to refine our many proven solutions, we are simultaneously pioneering new steel-production methods to facilitate technological progress in the metals industry.

Our close collaborations with leading steel producers empower us to achieve results unparalleled in the industry. We pay close attention to our customers’ requirements, determine what technologies will optimally support them in reaching their goals, and accompany them from the initial pre-planning phase of a project to the final training sessions for their staff, so that the highest-possible return on investment is ensured. As pioneers at heart, we inspire our customers to make the right choices for continued success in the world of metals.
