High-performance concrete steel truss floor decking is an integrated composite system consisting of steel trusses and a non-removable concrete bottom formwork. During construction, the composite deck can support fresh concrete and construction loads; after the concrete is poured, the steel trusses serve as the load-bearing reinforcement during the service life, while the concrete bottom formwork remains in place, forming a concrete interface on the underside of the slab that allows for direct finishing and decoration, significantly reducing construction time and overall project costs.
