BS 4449 is intended for manufacturers, fabricators and purchasers of ribbed reinforcing steel (bars, coils and decoiled products) for the reinforcement of concrete structures. It provides designations based on the grade of steel, the product form and dimensions. The standard is used to specify all normal technical requirements for reinforcing steels, including chemical analysis, mechanical properties, rib geometry and tolerances on dimensions.
