B500A/B500B
Coils of reinforcing steel according to DIN 488
Reinforcing steel in coils of steel grades B500A (material 1.0438) and B500B (material 1.0439) in accordance with DIN 488-1:2009-08, regulated in accordance with DIN 488-3:2009-08. This is reinforcing steel which is supplied in coils and is used on straightening and cutting systems as well as automatic ironing machines. Depending on the manufacturing process, reinforcing steel in coils has an almost circular material cross-section, which can also be oval depending on the manufacturing process, as well as a high or low ribbing, depending on the steel grade.
