Composite steel-concrete floors

A trapezoidal metal plate is used as working floor, formwork and reinforcement of the concrete compression layer.

Application: Used as floor system in (high rise) steel structures. Can be propped temporarily during casting which can lead to significant spans. The system offers relatively large flexibility for odd shaped floors.
