Product Description

VIDEO

BS 4449 is a British standard on steel for the reinforcement of concrete that discusses the criteria for manufacturing ribbed weldable reinforcing steel. BS 4449 specifies 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. BS 4449 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.
