Steel plate


High-yield-point steel plates for bridges (SBHS)

SBHS (Steel for Bridge High Performance Structures) features high-performance, high-tensile strength steel that was developed based on the results of a joint project carried out by industry and academia for the purpose of reducing the construction costs of steel bridges.


  • Higher yield strength than conventional steel (constant yield strength irrespective of sheet thickness)
  • Greater ease of fabrication and welding than conventional steel, eliminating preheating in some cases, and enabling reducing preheating temperature.
    Steel Yield strength
    Tensile strength
    Preheating Charpy test
    Test temperature (℃) Absorption energy (J) Test direction
    SBHS500 (W) 500 or more 570~720 Not required -5 100 or more Perpendicular to direction of rolling
    SBHS700 (W) 700 or higher 780~930 50℃ -40 100 or more
  • Charpy test conducted perpendicular to rolling direction; any plate design direction.
  • Improves ease of welding and cold fabrication, etc.; improves formability in manufacturing

NIPPON STEEL estimation results: 3-span continuous composite, 2 main girders (maximum span 60m)

  • Reduction in total construction costs:
    Maximum reduction of approximately 10%(using SBHS500)
  • Reduction of steel weight:
    Using SBHS500:Approximately 7% reduction (relative to SM570)
    Using SBHS700:Approximately 15% reduction (relative to SM570)

Examples of use

Tokyo Gate Bridge (Japan)

The use of SBHS reduced total weight by 3% and total construction cost by 12% (estimates by MLIT).

Nagata Bridge (Japan)

First use of NIPPON STEEL's SBHS high yield steel plate for bridges after this steel was covered by JIS.
