What structural role does metal decking fulfill in a construction project?

Metal decking serves a crucial structural role by providing a solid surface for floors and roofs. It is typically made of cold-formed steel and is installed as a structural element in commercial and industrial buildings. The decking acts as a working platform during construction and also serves as a permanent formwork for the concrete that is often poured on top of it. When the concrete hardens, it binds with the metal decking, creating a composite system that enhances the overall strength and durability of the floors and roofs.

This solid surface is vital for both load-bearing and safety purposes, allowing for the support of loads such as furniture, equipment, and people, while also providing a finished surface for the building. Unlike other roles such as temporary scaffolding, which is only designed for short-term use during construction phases, metal decking is intended for the long-term stability of the structure.
