How does steel deck flooring differ from reinforced concrete slab?
Steel deck is cold-formed steel sheet used as the formwork for a concrete slab. It suits multi-storey buildings because it cuts cost and speeds up construction.
- Saves consumables: the steel sheet carries the wet concrete itself, with no timber formwork propping needed.
- Reduces tension and cracking: after the concrete hardens, the sheet carries tension like reinforcement, so there is no risk of rebar being tied wrongly.
- Saves concrete: the profiled sheet uses less concrete, so the structure is lighter and passes less load to beams, columns and foundations.
Embossed ribs help the sheet bond with the concrete and resist horizontal shear, and shear connectors are needed at the beams. Example sheet weights:
