Company information
Our company was established as a business subsidiary on April 1, 2020, through the integration of the material and energy business of Japan Steel Works, Ltd. and the wind turbine maintenance service business, along with four group companies. Our Muroran Works is the birthplace of Japan Steel Works and has been involved in the development and manufacturing of pressure vessels and various industrial machinery, large cast and forged products, thick plates, and clad steel plates, which are essential equipment or major components used in social infrastructure and various plants for over a hundred years. In response to the advanced and diversified needs for materials, we provide various components (M: Materials), including steel, non-ferrous metals, and composite materials. Leveraging our technology and experience, we offer a one-stop solution that encompasses design, manufacturing, construction, installation, maintenance inspection, analysis evaluation, and repair, enabled by our engineering (E: Engineering) capabilities to meet our customers' wide-ranging needs.
