Floor Deck

Firth Steels designs engineered steel floor deck systems that provide strength, efficiency and durability.

Selecting the right floor deck system enhances load-bearing capacity and improves installation speed and fire resistance.

Our R51+, TR60+ and TR80+ profiles provide tailored solutions that effectively accommodate a wide variety of construction and engineering needs.

Consequently, installers can optimise material efficiency while simultaneously enhancing structural performance and reduce overall project costs.

R51+

A traditional re-entrant profile, commonly used in inner-city multi-storey projects where optimising the structural zone and minimising storey height are essential for maximising space efficiency.

R51+

Benefits
  • 51mm deep re-entrant profile
  • 101mm minimum slab depth, whilst still achieving 1 hour fire rating
  • With minimal voids in the concrete section this allows dense slabs to be constructed providing good sound insulation
  • Soffit ‘Wedge Nut’ fixings available with load capacity of up to 2kN
  • Narrow re-entrant ribs provide virtually flat soffit
  • Acoustic Robust Solution – Refer ‘Robust Standard Details’
  • TAB-DeckTM fibre concrete solution now available
  • Wide flat trough provides flexibility for shear stud positioning

TR60+

Benefits
  • 60mm deep trapezoidal profile
  • Reduced concrete volume
  • Enhanced speed of installation due to the 1.0m cover width
  • Trough stiffeners positioned to ensure central stud position, reducing amount of site checking required
  • The steel cross sectional area of this profile makes it the most economical option of the three available profiles
  • Soffit ‘Wedge Nut’ fixings available with load capacity of up to 1kN
  • Acoustic Robust Solution – Refer ‘Robust Standard Details’
  • TAB-DeckTM fibre concrete solution now available

TR80+

Benefits
  • 80mm deep trapezoidal profile
  • Reduced concrete volume when compared to other decks availabel on the market
  • 140mm slab depth required to achieve a typical 1 hour fire rating
  • Excellent un-propped span capacity
  • Trough stiffeners positioned to ensure central stud position, reducing amount of site checking required
  • Soffit ‘Wedge Nut’ fixings available with load capacity of up to 1kN
  • Acoustic Robust Solution – Refer ‘Robust Standard Details’
  • TAB-DeckTM fibre concrete solution now available
