BS4449:2005 B500B is a British standard specification for hot-rolled ribbed steel bars used for the reinforcement of concrete structures. The "B500B" designation indicates the steel grade, which has a minimum yield strength of 500 megapascals (MPa) and a minimum tensile strength of 550 MPa.
Hot-rolled ribbed steel bars are commonly used in construction projects to provide reinforcement and improve the strength and durability of concrete structures. The ribbed surface of the bars enhances the bond between the steel and concrete, ensuring effective transfer of stresses and improving the overall performance of the reinforced concrete.
BS4449:2005 B500B specifies the dimensional and mechanical properties of the steel bars, including the diameter, mass per unit length, and the permissible deviations. It also provides requirements for the chemical composition, weldability, and ductility of the steel.
This standard ensures that the hot-rolled ribbed steel bars meet the necessary quality and performance criteria for use in construction projects in the United Kingdom. Compliance with BS4449:2005 B500B is typically required by engineers, architects, and contractors to ensure the safety and reliability of reinforced concrete structures.

Example of a rib pattern for the grade B500B Reinforcing bars have two or more parallel rows of transverse ribs. When there are two or three rows of transverse ribs, one row is angled opposite to the other rows; when the rebar has four rows of transverse ribs, two rows are angled in the opposite direction to the other two rows. The figure shows an example of grade B500B with 4 rows of transverse ribs. |
