Efficient Spanning Ability
With unpropped spans of up to 3.0 metres, the CF46 is perfect for projects requiring lighter structures and reduced support beams. It enables flexibility for both commercial and residential construction.
Optimised Slab Depth:
Achieves slab depths ranging from 100–130mm, ensuring excellent strength while minimising concrete use. It’s often used as an alternative to Lewis Deck due to its availability, with typical delivery times within two weeks and fewer components to manage on site – making it a highly convenient option.
Fire Resistance
The CF46 offers fire resistance of up to 90 - 120 minutes when paired with appropriate reinforcement and slab depths, providing peace of mind for both residential and commercial applications.
Perfect for All Scales of Development
Whether you're working on a residential renovation, an extension, or a larger commercial space, the CF46 delivers a professional finish. Its lightweight yet durable structure ensures quick construction times without compromising on quality or safety.
Versatility Across Applications
From high-rise developments to domestic renovations and new builds, the CF46 adapts to a variety of settings, offering an economic and environmentally friendly solution for diverse projectsCompliance with Design Codes and Standards (see technical).
