Corporate History

March 1976 Manufacturing method and production equipment for large diameter square hollow sections were recognized as new national technologies by the Agency of Industrial Science and Technology of the Ministry of International Trade and Industry of Japan. This resulted in the company being offered a special loan by a government-affiliated financial institution.
March 1978 Kuzuryu-gawa Factory began operations. With the recommendation of the Agency of Industrial Science and Technology of the Ministry of International Trade and Industry, an automated, labor-saving production line was constructed at the Kuzuryu-gawa Factory in Fukui Prefecture with the aim of becoming the first to obtain Japanese Industrial Standards accreditation as a national technology. The factory led the industry in achieving the mass production of large diameter square hollow sections. U.S. and Japanese patents were awarded for the manufacturing process.
December 1984 To further increase the maximum diameter, a 26-inch electric resistance welding facility made by Sumitomo Heavy Industries, Ltd., with one of the largest roll forming furnaces in the world, was installed at the Tenryu-gawa Factory.
May 1992 The Tenryu-gawa Factory received Japanese Industrial Standards (JIS) certification.
April 1993 Hamaoka Factory began operations. A machining facility for pipe cutting and grooving for large diameter square hollow sections was installed to establish a quick shipping system.
April 1995 Engaged in technical collaboration for hot formed tube manufacturing process with the Pipe & Tube Division of British Steel Corporation (currently Tata Steel Ltd.), completed the most advanced hot forming manufacturing line at the Tenryu-gawa Factory using exclusive technology, and began full-scale mass production of the Super Hot Column (SHC) hot formed square hollow sections.
May 2003 Developed Super Hot Column Jumbo (SHCK), which keeps its design strength (F value) at plate thicknesses exceeding 40 millimeters, and began commercialization.
June 2003 Newly-constructed Omaezaki Factory began full-scale operations. Manufacturing facility for large diameter square hollow sections featuring world-class press forming processing led to enhanced quality, mass production and reduced costs.
November 2005 Jointly developed the high-performance cold press formed square structural hollow section NBCP325EX with Sumitomo Metal Industries, Ltd. (currently Nippon Steel & Sumitomo Metal Corporation) and obtained certification from the Ministry of Land, Infrastructure, Transport and Tourism of Japan.
December 2006 Developed the high-performance cold press formed square column NBCP440 jointly with Sumitomo Metal Industries, Ltd. (currently Nippon Steel & Sumitomo Metal Corporation) and obtained certification from the Ministry of Land, Infrastructure, Transport and Tourism of Japan.
March 2009 Developed a non-diaphragm construction method for the beam-pillar joint using the Super Hot Column.
April 2009 Obtained the CE Mark, European safety standard, for EN10210 and EN10219 from TÜV Rheinland.
March 2010 Jointly developed the high-performance cold press formed square column NBCP385 with Sumitomo Metal Industries, Ltd. (currently Nippon Steel & Sumitomo Metal Corporation) and obtained certification from the Ministry of Land, Infrastructure, Transport and Tourism of Japan.
January 2011 Installed a machining facility for plate edge milling made by Linsinger at the Omaezaki Factory to enhance welding quality and doubled tube manufacturing capacity.
