Social infrastructure that supports our lives. In the physical structures, you will always find steel products.

With our superior technology and quality, Pacific Steel Mfg. is friendly to nature and contributes to society.

Since its founding in 1938, Pacific Steel Mfg. has a corporate philosophy of "Gentle with Nature and Contribute toward the Social Progress by fine Technology and Quality" and forged steel with an integrated production system from steelmaking, forging, heat treatment to machining in Hokuriku Toyama. We have developed as a specialized manufacturer that produces products.
Our own brand NT-Rolls, which was developed with our main product, our own technology, is excellent as a so-called hot rolling roll of shaped steel that is used in large quantities for infrastructure equipment such as railroads, bridges, blast furnaces and revetment works. Due to its durability, it has been patronized by steel companies in Japan and overseas, including blast furnace manufacturers, for many years.
In addition, as turbine parts for generators, a series of large valves that control ultra-high temperature and high-pressure steam, stable high-speed rotation over a long period of time under ultra-high temperature and high pressure, and the highest level of quality required for forged steel products are required. We have delivered to most heavy electric plant manufacturers involved in nuclear power generation from water and thermal power, such as turbines and rotors, generator shafts, thick-walled piping members, flanges, etc., and have received high reliability and evaluation.
In addition, we are a competitive manufacturer in terms of quality, price, and delivery time for general forged steel products required by various industrial machinery industries.

We will continue to make further efforts in collaboration with related group companies and continue to supply unique forged steel products to contribute to society.

CSR / Environmental Initiatives
Iron is a material that can be recycled many times, and almost all of it is collected and reused. At Pacific steel mfg., the iron scraps generated by machining are melted again in an electric furnace and used for manufacturing. The power plant materials we make are also used in power plants that use renewable energy such as geothermal power generation and biomass power generation. We are doing eco-friendly business using iron.
