Structural Shapes
Leading the New Era on Structural Shapes with Pioneer Spirits.
We, NIPPON STEEL, since the dawn of the Japanese steel industry, when we started producing Japan's first railroad rails in 1901, and through the nation's reconstruction period after World War II, have been the sole producer of rails and sheet piles in Japan and have contributed to the development of the Japanese economy. Based on our technological advantages and credibility, which were built-up during this process, we pioneered the production and sale of Japan's first rolled wide flanges and, with our half a century of technological innovation, have been responding to a wide variety of customers needs both in Japan and across the globe.
We have also produced and marketed: structural H-shapes with incremental depth and width of 50mm pitch（NSHYPER BEAM™, 1989）; structural H-shapes with fire-resistance（NSFR™ steel, 1990）; and other innovative products that span the history of construction in Japan. Working together with end users, we have also endeavored to spread the use of steel structures in building construction and promoted the use of structural H-shapes as well as developed key technologies in design, fabrication and construction fields.
Not resting on our laurels gained through history and experience, we have determined to lead the new era with pioneer spirits and express the hope that NIPPON STEEL's structural H-shapes will continue to
enjoy your company's patronage.

Production Process(Case of Kansai Works (Sakai))
- 1Edge rolling mill（variable caliber depth of upper and lower rolls）
Meeting the need for widely ranging web thicknesses by varying upper and lower roll positions to produce fixed widths
- 2Skewed roll rolling mill
Flexible control of depth using skew rolls
- 3Finish rolling mill
Provision of wide-ranging flange thicknesses by controlling the depth to a fixed level and changing upper/lower roll-body widths
Kansai Works (Sakai), rolling freely to achieve due to size by variable-width rolls and skew-roll rolling, a first-of-its-kind rolling, has established the manufacturing technology of the "NSHYPER BEAM™".
