Product parameters

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.

a) Rm / Re1.03 and Agt 2.0 for center lines ≤ 5.5 mm
b) Agt for coils + 0.5%
c) Rm / Re min. 1.13 and Agt 7.0% for center lines ≤ 12 mm
d) Maximum voltage ripple 2σa with upper voltage 0.6Rek (300 MPa) and 1 million voltage changes. For spot welded reinforcement mesh B500B and B500C, 2σa is at least 100 MPa. For coil-oriented products, 2σa is at least 100 MPa, unless a higher value (≤ 175 MPa) is statistically demonstrated for the maximum diameter used and for the targeting machine (type) concerned.
e) For lattice girders, the lower bars must comply with B500A and / or B500B with the fR / P requirement. The upper bars and diagonals may be reinforcing steel with only the requirements of Re, d and the chemical composition.
f) For coils fR (ribbed) + 15%, fP (dented) + 5%. No requirement for weakly profiled / dented reinforcing steel (lattice girders).
