BS 4449:2005 + Amendment 2 2009 Specification for carbon steel bars for the reinforcement of concrete

BS 4449 has been amended and is the British standard that specifies the requirements for ribbed weldable reinforcing steel used for the reinforcement of concrete structures. BS 4449 covers steel delivered in the form of bars, coils and decoiled products. The standard contains provisions for three steel grades, all of 500 MPa characteristic yield strength, but with different ductility characteristics. The three grades are B500A, B500B and B500C.

BS 4449 specifies the weldability requirements for all grades of steel, in terms of the chemical composition, and in particular the carbon equivalent value.

BS 4449 does not cover steel bars produced by re-rolling finished products, or by rolling material of which the metallurgical history is not fully documented or not know.

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.

BS 4449:2005+A 2009 is a revision of BS 4449:1997 Specification for carbon steel bars for the reinforcement of concrete which has been withdrawn.

BS 4449 includes the following cross references:
