Ordinary steel bars 'KurokonTM' Screw rebar 'Neji barTM'

'Steel bars for concrete reinforcement of JFE Bars and Shapes Corporation'

① Features of Our Product

2. We provide grades with warranty for toughness.

We provide grades with warranty for toughness (rebars with limited maximum yield strength to 1.1 t imes 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.

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.

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.

1. 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 (D10-D51) and the strength (SD295A-USD685B and JH785). This enables reliable and economical designs.
