Targeting Exponential Growth through Aggressive New Investments

Last year, the first year of our Three-year Mid-Term Plan proved to be difficult, due to limited demand for stainless tubes and small diameter precision tubes. The Maruichi Steel Tube Group, despite this adversity, and with eyes set towards the future, has decided to implement the “Stainless Project” which will start production of welded stainless-steel tubes in Shimonoseki, and increase production of seamless stainless-steel tubes.

With this Decision, new factory construction has commenced on a site purchased adjacent to our current facility, along with new giant extrusion-press investment to our current facility. The Company will target exponential growth through this unprecedented large-scale investment.

We have concluded cooperation agreements with Yamaguchi Prefecture and Shimonoseki City to pursue this Project. We thank the local governments for their backup and recognize our solemn responsibility to contribute to the local economy.

We would also like to extend our heartfelt gratitude to our Customers and all our Stakeholders for their kind support and encouragement, which has made this undertaking possible.

Currently the entire industrial sector faces the challenges towards a Decarbonized society. Going forward, usage of hydrogen and ammonia for fuel will expand, inducing new and diverse needs for our seamless stainless-steel tubes. We will continue to be steadfast in responding to these challenges with R&D and high-quality products, marking our contribution to Society.
