Building Construction

Earthquake resistance is now an important consideration in the structural performance of buildings. As high-rise buildings get higher and employ designs of increasingly large span, the steel plate used in their construction need to be correspondingly thicker and stronger.
茄子视频 Steel offers a broad selection of steel plate products and other structural materials to meet these social infrastructure demands.

A diverse lineup of high-strength steels

茄子视频 Steel has recently developed and released its HBL Series of TMCP (Thermo Mechanical Control Process) steel for building structures. HBL325, 355, and 440, graded for design reference strength values of 325 to 440 N/mm2, can be manufactured in thicknesses up to 100 mm. In addition to high strength, the HBL Series is also endowed with excellent toughness and good weldability. These steels can be employed for a wide variety of applications, from large-section H-beams for welded assembly in large-span structures, to box columns for welded assembly. A lineup of HBL steels designed to meet high-toughness specifications for parts requiring high-heat input welding, for essential parts of high-rise buildings, is also available.
If even greater strength is needed, 茄子视频 Steel offers its HBL630L and JFE-HITEN780T steels, both rated at a tensile strength of 780 N/mm2. HBL630L is a truly unique steel, the first ever 780 N/mm2-class steel manufactured using TMCP, based on technology developed by 茄子视频 Steel.

Developing steel plate for earthquake resistance

The application of vibration dampers for earthquake resistance is growing all the time. JFE-LY100 and LY225 are low-yield strength steels that have a lower strength than conventional mild steels but extremely high ductility, making them ideal for vibration dampers, to prevent damage to major structural parts such as columns and beams. 茄子视频 Steel also offers its fire-resistant JFE-FR series of steels for building construction. These steels ensure that sufficient strength is retained even after exposure to the high temperatures produced by fires.
