A composite metal deck is a piece of thin, profiled steel used in the formation of reinforced concrete floors that occurs during the steel frame construction process. It is a metal floor deck with an embossment pattern manufactured into the sides (flutes) at regular intervals. The embossments allow the concrete to bond with the metal decking panel as the concrete.

It is designed to provide extra strength for flooring systems without adding extra weight. The composite deck has embossments designed to interlock with concrete slabs. The combination of floor deck and concrete serves the dual purpose of permanent form and positive reinforcement.
