07 Assessment
Advantages
- Eliminates need for temporary formwork stripping
- Provides permanent tensile reinforcement
- Reduces construction time significantly
- Creates safe working platform during construction
- Excellent spanning capabilities reducing propping requirements
- Composite action saves concrete and reinforcement costs
- Fire resistance up to 240 minutes with appropriate topping
- 100% recyclable at end of life
- Suitable for all Australian climate zones
- Compatible with various frame types (steel, concrete, masonry)
- Allows service integration in rib cavities
- Reduces overall structural depth
Constraints
- Requires skilled installation for optimal performance
- Initial cost higher than conventional formwork
- Acoustic performance primarily dependent on concrete topping
- Thermal bridging through steel profile
- Limited availability of some thicknesses (0.90mm special order)
- 1.20mm BMT not available for deck sheets
- Requires appropriate edge protection during construction
- Corrosion protection needed in marine environments
- Deflection control critical during concrete pour
- Weather-dependent installation conditions
