A traditional flat pan profile that provides unmatched performance in suspended concrete slabs. Can be used in both concrete and steel frame construction and utilises patented technology to achieve superior spanning capabilities, less deflection and greater composite strength than similar re-entrant profiles.

  • Stronger than similar decks due to the patented corner embossments
  • Stronger than similar decks in positive bending and end shear due to the dovetail ribs which resist lateral deflection by up to 10%
  • Works as composite slab saving on concrete and reinforcement costs
  • Available in standard DECKFORM® steel in QLD/NT or BONDEK BLUE®* in NSW/ACT, featuring a blue anti-glare coating reducing reflected light by a minimum of 80%, which means greater comfort for installers and follow up trades on site
