Double Tee flooring units consist of two prestressed ribs and a connecting top slab. The depth of the double Tee can vary from 200 to 550mm. The connecting slab or flange is 2400mm wide x 50mm thick. Double Tees are ideally suited for larger spanning floors with a wide variety of services suspended from the flooring system. Double tees can easily accommodate large floor voids/penetrations through the slab region. The cast insitu topping is a min 65mm thick.
A major practical benefit of a concrete floor is its ability to reduce noise transmission
Fire Resistance Rating
2400mm wide unit = 90min fire resistance rating. Increased fire ratings can be achieved with specific design.
Double Tee strength = 45 MPa at 28 days
Topping strength = 20 MPa at 28 days
