Easy installation without the need for grout material! A compact and well-fitting mechanical rebar joint.
The 【EG Joint】 is a mechanical rebar joint that connects rebar ends joined by friction welding with couplers and tightens with lock nuts. It does not require special techniques, allowing for a reduction in construction time. Because it is groutless, temperature management is unnecessary, and no industrial waste is produced. 〇 Obtained the performance evaluation standard for rebar joints【Class A】 in the 2007 edition of the Technical Standards for Structural Design of Buildings (Evaluation Number: BCJ Evaluation-RC 0001-04 by the Japan Architectural Center) 〇 Confirmed the joint performance of the Japan Society of Civil Engineers' "Rebar Anchorage and Joint Guidelines [2007 Edition]" as【Class SA】 【Features】 ○ Sizes D13 to D51, Steel grades SD295 to SD490 ○ Only requires tightening with a torque wrench, no grout material needed ○ Easy installation enables a reduction in construction time ○ Compact design with good fit ○ High reliability as all stress transfer occurs through steel 〇 Can be used as a lightning rod conductor for RC structures 〇 No industrial waste produced as no grout material is used 〇 No ultrasonic inspection required For more details, please contact us or download the catalog.

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.
