Steel pipe manufacturing and distribution: two faces

In 1902, after founder Ichijiro Nobe first introduced Japan to the “cold drawn steel tube” technology that he learned while in Germany, he began working in social development through ironwork with operations centered on the manufacturing and sale of steel pipe. Now the company is situated in Sasebo City, possesses nine operation centers around Japan, and has been built into a system that responds to customer needs.
