Truss floor deck, also known as reinforced truss formwork, is a composite structural system formed by manufacturing the main reinforcing steel into a truss at a factory using specialized equipment, and then welding the truss to galvanized steel plates. During the structural floor construction phase, this system replaces the construction formwork with galvanized steel plates, which are welded to the reinforcing steel within the structure to form a truss structure that collectively bears the weight of the concrete floor and construction loads. After the concrete is poured, it forms a reinforced truss concrete floor that withstands service loads during use.
