Please contact to the following contacts for details. Hot-dip galvanized rebar protects concrete structures from salt damage. The mechanical properties and adhesion performance to concrete are the same as rebars specified in JIS G 32. -New development- We also provide environmentally friendly 'cadmium- and lead-free coating'. <Contact> Approved by the Building Center of Japan Tanaka Galvanizing Co., Ltd.Phone(8) URLhttp//z-mekki.com Nasu-Denki Tekko Co., Ltd.

6 Product Overview Features of Our Product We contribute to the development of society and create new value. 'Steel bars for concrete reinforcement of JFE Bars and Shapes Corporation' Ordinary steel bars 'Kurokon TM ' Screw rebar 'Neji bar TM '. Available for low- to high-rise buildings The products are available for various structures and structure parts, form low- to high-rise buildings, as they are manufactured in a wide range of diameter (D0-D5) and the strength (SD295A-USD685B and JH785). This enables reliable and economical designs. 2. We provide grades with warranty for toughness. We provide grades with warranty for toughness (rebars with limited maximum yield strength to. times of standard strength or less, or special specification such as the maximum limit of yield ratio). This enables the collapse mechanism that provides the prior type by beam bending yield, realizing structures with high energy absorption performance. 3. Advanced material characteristics Our products offer excellent weldability and pressure weldability since they are produced under strict quality control from steelmaking to rolling with adequate chemical composition adjustments. Our products also have advanced bending characteristics as the transverse rib is carefully shaped. 4. Flexible delivery system With the rebars mostly based on the same standard produced in Hokkaido, eastern Japan and western Japan, we can arrange delivery from the closest manufacturing plants for the locations of demand.
