Multideck Floordecking System

Multideck is a high performance, profiled, galvanised steel floor decking for use in the construction of composite floor slabs. The range consists of four different profiles; 50, 60, 80 and 146.

1. Large range of section decks and depths to suit all applications.
2. Unique profile requires less concrete than other decks to achieve any given slab thickness.
3. Gauge range 0.85mm through 1.5mm for economic solutions.
4. Fire performance up to 4 hours.
5. Acoustic robust solution.
6. Spans up to 6 metres unpropped.
7. Mesh or Dramix steel fibre reinforcement.
