Hot-rolled Rebar
Hot-rolled Rebar Introduction
Rebar is also known as hot rolled ribbed steel bar. The grade of ordinary hot rolled reinforced rebar is marked by the HRB, which stands fir the minimum yield point of the material.
(Hotrolled)R(Ribbed)B(Bars)Hot-rolled Rebar HRB335(20MnSi),HRB400(20MnSiV,20MnSiNb,20Mnti),HRB500.
Refers to the reinforced concrete with steel reinforced concrete reinforcement with straight or plate of
strip steel, its appearance is divided into two kinds, light round steel and deformed steel delivery status
for the straight bar and wire rod in two.
Rebar in concrete main tensile stress. Deformed bars as a result of the action of rib, and concrete
have larger bonding ability, thus better able to withstand the role of external force. Steel is
widely used in all kinds of building structure, especially large, heavy, light thin wall and high-rise building structure.
Weight calculation formula:W= 0.00617 ×d×d d= section diametermm
