Reinforcing bar




Celsa produce Grade B500C high ductility hot rolled, ribbed steel bar, for use in the reinforcement of concrete. Our Grade B500C reinforcing bars meet all the requirements of BS 4449:2005 + A3:2016 Grade B500C, are fully weldable, and are available in all BS 4449:2005 preferred sizes, from 10 to 50 mm.

All our BS 4449:2005 + A3:2016 reinforcement is CARES approved, and is certified to the BES 6001 responsible sourcing standard through the Eco-Reinforcement responsible sourcing scheme.

Applications

  • For general reinforcement of concrete structures.
  • Moment distribution (up to 30%) in reinforced concrete design
  • Additional ductility allows plastic/non-linear design
  • Additional ductility and cyclic performance make it suitable for any potential overload situations where inherent robustness is important
  • Other design applications include: pile caps, retaining walls, shear walls, beams and columns.
