Product Description

The Differences Between B500A, B500B, and B500C

The differences between the A, B and C designations are complex and relate to structural tolerances. For reinforcement mesh products, grade B500A steel is typically used, and for rebar, B500B is used. B500C steel is seldom requested and it would always be worth checking with a structural engineer whether grade B500B could be used instead of B500C, since B500C typically has a significant cost overhead.

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