BS4449 Steel Rebar is a British standard weldable hot-rolled ribbed rebar for concrete reinforcement, mainly including B500A/B/C grades with a characteristic yield strength of 500MPa and differentiated ductility performance. Compliant with BS EN 10080, it has a diameter range of 6-50mm and excellent weldability, cold workability and concrete bonding performance. With strict control of chemical composition and carbon equivalent, it features stable mechanical properties, reliable tensile strength and good fatigue resistance. It’s the mainstream reinforcement material for concrete structures in British and Commonwealth engineering projects with high construction standard requirements.
