Compared to ordinary rebar (SD bar), the design stress can be increased up to four times, significantly reducing the amount of shear reinforcement used.
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 can increase the design stress by up to four times, significantly reducing the amount of rebar used and contributing to improved work efficiency, cost reduction, and shortened construction periods at construction sites (resource conservation, CO2 reduction). Additionally, by accommodating the high-strength requirements of columns and beams in reinforced concrete (RC) structures, it enables the construction of super-tall buildings over 60 meters high. * A design method using bonded split reinforcement bars (based on plastic theory shear resistance formulas and patented methods by Netsuren) has been established, allowing for reinforcement of up to 1.5% as P_w + P_b (bonded split reinforcement ratio).

Company information
Netsuren successfully commercialized and industrialized IH (Induction Heating) technology for the first time in Japan in 1946 (Showa 21). This IH technology is a double eco (Ecological and Economical) technology that uses clean electricity as its heat source, making it environmentally friendly and pollution-free. As a pioneer in this field, Netsuren has developed highly original products in addition to contract heat treatment processing, based on the know-how accumulated since its founding and its high level of technical and development capabilities, bringing transformation and contribution to various industries. The fact that Netsuren exists today and can contribute to society, even in a small way, is thanks to your unwavering support and warm patronage. To enhance corporate value through harmony and coexistence with customers, business partners, shareholders, society, and employees, Netsuren aims to remain a company with a dignified presence in the future. We will return to the founding principle of "Technology of Netsuren" and continue our tireless efforts to be of greater service to society in the coming era.
