Deck sections are used in many composite floor slab applications wherein the steel deck serves not only as of the form for the concrete during construction but also as the principal tensile reinforcement for the bottom fibres of the composite slab. The term “composite steel deck floor slab” is applied to systems in which the steel deck has some mechanical means of providing positive interlocking between the deck and the concrete.

Steel deck profiles generally are classified as two types, namely cellular and non-cellular deck.Cellular decks differ from non-cellular ones in that the cellular deck profile has closed cells formed by an added sheet of steel connected to the bottom corrugations of the deck. The closed cells are often used for electrical, communication, or other utility raceways within the floor system. In some instances, utility raceways are blended with the composite deck profiles

A composite slab with profiled steel decking has proved over the years to be one of the simpler, faster, lighter, and economical constructions in steel-framed building systems. The system is well accepted by the construction industry due to the many advantages over other types of floor systems. Since the last decade, the construction industry has been looking beyond the conventional methods and exploring for the better to win over today’s challenges, and therefore, composite slab construction is one of the viable options.
