Build Stronger, Smarter Floors with Fibre Enhanced Composite Decking
Composite metal decking systems combine profiled steel deck and a concrete topping to create a highly efficient, load-sharing structural floor. When fibre reinforcement is added to the concrete, it not only improves crack control and durability, but also enhances fire resistance — delivering structural performance while potentially reducing reinforcement material requirements, subject to project design and engineering calculations.
Why Use Fibre Reinforcement?
Adding steel and synthetic fibres into the concrete topping provides engineering and performance benefits:
Crack Control: Reduces early-age shrinkage cracking
Fire Resistance: Supports performance during fire exposure
Load Sharing: Optimises the composite action between steel deck and concrete
3-Dimensional Reinforcement: fibres are spread throughout the concrete and can reduce or eliminate the need for steel mesh in approved applications, subject to project design requirements.
Approved Decking Systems
We currently support two major composite decking systems with approved fibre dosage specifications:
ComFlor® (Tata Steel)
MetFloor® (Composite Metal Flooring / CMF)
Fibre Dosage Guidelines
Fibre dosage is based on fire rating requirements and loading calculations. The combined use of Novocon FE10-50 steel fibres and SikaFiberMesh 150-ML is designed to support structural and fire performance requirements when used in accordance with the approved specification.
| Fire Rating | Fibre Dosage (per m³) |
| 60 minutes | 25 kg Novocon FE1050 + 1 bag SikaFiberMesh 150-ML |
| 90 minutes | 30 kg Novocon FE1050 + 1 bag SikaFiberMesh 150-ML |
| 120 minutes | 35 kg Novocon FE1050 + 1 bag SikaFiberMesh 150-ML |
Specification Support
Use our fibre concrete design software to calculate the optimal fibre dosage based on your project's deck system, fire rating, and loadings. Combined with our CPD offering, you’ll be fully equipped to specify fibre reinforced composite decks with confidence.
