Properties
¡ôHRB400 has high tensileand compressive strength ,and can save cost by 30%-40% if replacing traditional re-bar with outstanding economical benefits .
¡ôGood cold bending properties .Meanwhile can solve the problem of over density of re-bar laying , as eases grouting and increases working efficiency .
¡ôLittle carbon quivalent weight with good welding properties .
Application
Mainly used in construction and weld-mesh .
