Bibliography
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.

This British Standard specifies requirements for ribbed weldable reinforcing steel used for the reinforcement of concrete structures. The standard covers steel delivered in the form of bars, coils and decoiled products. The standard contains provisions for three steel grades, all of 500MPa characteristic yield strength, but with different ductility characteristics. The three grades are B500A, B500B and B500C.
The weldability requirements for all grades of steel are specified in terms of the chemical composition, and in particular the carbon equivalent value.
Steel bars produced by re-rolling finished products, or by rolling material of which the metallurgical history is not fully documented or not known, are not covered by this British Standard.
NOTE Flash welds in lengths of bar are permissible under this standard, provided all the mechanical requirements are met. However, for some purposes, purchasers might specifically require bars without flash welds, and if so this ought to be stated at the time of enquiry and/or order.
