Profile

Benefits

  • Most suitable to irregular building footprint
  • Provides strongest composite slab performance
  • Offers thinnest slab depth options
  • Aesthetically pleasing soffit appearance

Updated from the original R51 product in 2018, this profile is available in S350 and S450 grades to provide the designer greater flexibility.  R51+ is a traditional re-entrant profile commonly used on inner city multi-storey projects where the structural zone and storey height is reduced, due to the relatively thin slab depth required to achieve a typical 1 hour fire rating.
