Zero waste with groutless technology! A highly reliable joint that excels in workability and achieves a short construction period. [*Established Kanto Day Bar Steel Co., Ltd. on October 1, 2019]
In 2019, Kanto Devar Steel Co., Ltd. was established as a joint sales company by Nippon Steel Corporation and Asahi Kogyo Co., Ltd. The "EG Joint/EG Splice Joint" is a joint that integrates by aligning screws joined at the ends of rebar through friction welding and connecting them with a coupler. Since it only requires tightening with a torque wrench and does not need grout material, there are no constraints on the construction period, and no industrial waste is generated. 【Features】 ■ Environmentally friendly as it is groutless ■ Excellent workability enables a shorter construction period ■ Highly reliable friction welding joint ■ Achieves a clear force transmission mechanism without interference from materials other than steel ■ NETIS registration number KT-160128-A *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Our company has contributed to society through the provision of steel products that support infrastructure, based on the steelmaking technology we have cultivated for over half a century since 1937. This includes reinforcing bars that support reinforced concrete structures, which are a major construction method in civil engineering, as well as wire rods and shapes used in various urban infrastructures, and structural bars that serve as key components in industrial machinery. During this time, we have consistently worked on advancements in production and product technology, responding to societal and customer demands by developing mechanical coupling methods for reinforcing bars that improve productivity in construction, high-strength steel, and providing steel materials that enhance workability and reduce processes for our customers. While steel production is expanding globally, in our country, which is a steel advanced nation, the generation of steel scrap, which consists of steel products that have already reached the end of their useful life, is quantitatively sufficient to support steel production in the civil engineering sector, which is the core of domestic infrastructure development. The role our company plays in the "reutilization" of iron resources, utilizing domestic resources like steel scrap with minimal energy to contribute to the formation of social capital, is becoming increasingly important. The harmony of people, technology, and the natural environment is essential, and the Joint Steel Group will steadily advance in pursuing the unknown realms and possibilities of iron.
