Design & Specification Notes
Profiled steel deck with concrete topping for efficient secondary floor spanning.
Typical Uses
- •Primary frame
- •Long-span elements
- •Load-bearing supports
Key Performance
High load-bearing capacity for primary frame.
Specification Actions
- •Provide an EPD (EN 15804) or verified embodied carbon figure (A1–A3), and state the life-cycle stages covered.
- •Specify high recycled content steel deck and optimise deck gauge
- •Plan to separate materials at end of life with easy-to-remove connections
Indicative Health & Indoor Air
Inert once cured. Dust during cutting requires PPE.
