HRB400 Reinforced Deformed Steel Rebar
Rebar is widely used in civil engineering construction such as houses, bridges, and roads. From highways, railways, bridges, culverts, tunnels, flood control, dams and other public facilities, to the foundations, beams, columns, walls and slabs of housing construction, rebar are all indispensable structural materials.
HRB is the English abbreviation of hot rolled ribbed bar, that is, hot rolled ribbed bar. The so-called ribbed bar refers to the deformation of the reinforcement surface through hot rolling process to increase the bite force with concrete, including surface ribbed bar, spiral bar, herringbone bar, crescent bar, etc.
HRB335 (20MnSi), the standard value of yield strength of the reinforcement is 335mpa, the diameter is 6 ~ 50mm, and the elastic modulus is 200GPa. HRB400 (20MnSiV, 20MnSiNb, 20mnti), the standard yield strength of the reinforcement is 400MPa and the design value is 360MPa. The diameter is 6 ~ 50mm and the elastic modulus is 200GPa. The reinforcement symbol hrb400e with e refers to ordinary hot-rolled ribbed reinforcement with strength grade of 400MPa and seismic performance. The core of reinforcement with E is that the super yield ratio index of reinforcement shall not be too large, while the strength yield ratio and elongation index shall not be too small.
