Rebar

Rebar is the common name for hot - rolled ribbed bars. For ordinary hot - rolled bars, their grades are composed of "HRB" and the minimum yield point value of the grade. "H", "R", and "B" are the first letters of the English words "Hotrolled", "Ribbed", and "Bars" respectively. Hot - rolled ribbed bars are divided into three grades: HRB335 (the former grade was 20MnSi) for grade II, HRB400 (the former grades were 20MnSiV, 20MnSiNb, 20Mnti) for grade III, and HRB500 for grade IV.
