"High-strength shear reinforcement bar Ulbon 1275" additional new wire diameter U11.8

Added a new wire diameter U11.8 to the 'High Strength Shear Reinforcement Bar Ulbon 1275.' By applying the optimal wire diameter according to the project, further reduction in rebar quantity is possible.

The 'High-Strength Shear Reinforcement Bar Ulbon 1275' is a deformed PC steel bar certified by the Minister of Land, Infrastructure, Transport and Tourism, with a yield point of 1275 N/mm² and a tensile strength of 1275 N/mm². Compared to conventional ordinary rebar (SD bars), it allows for a maximum design stress up to four times greater, significantly reducing the amount of rebar used and contributing to improved work efficiency, cost reduction, and shortened construction periods at job sites (resource conservation, CO2 reduction). With the addition of the new bar diameter U11.8 to the lineup, further design options tailored to various member cross-sectional widths have become possible. The new bar diameter U11.8 demonstrates effectiveness with column cross-sections of 1,100 mm square for heights of 30 to 60 meters (levels 10 to 20), enabling approximately a 10% reduction in rebar quantity compared to conventional diameters. * The new bar diameter U11.8 has already obtained certification from the Minister of Land, Infrastructure, Transport and Tourism and evaluation from the Japan Building Center (general construction method and welded joint method).
