Mabo produces this tile in a large range of heights to satisfy all kinds of demand, as regards the capacity lead and the fire resistance.

The TT tile is used to cover great lengths (up to 24 m) of industrial or commercial buildings or mono or multi-storey car parks. This tile is formed by two variable height legs taking the prestressing reinforcement and the eventual loose reinforcement and a reinforced concrete slab with a thickness of 5 cm, a width of 2,5 m and a variable length.

The TT tile is erected upon L or T shaped beams with a distance extrados beam - extrados lower flaps like the tile height. So, once erected, the tile produces with the extrados of the floor holder beams an uninterrupted plane ready for the composite casting.
