A metal deck is a structural panel element that acts as the surface of a floor or roof. The deck is roll-formed from structural quality sheet steel and is engineered to span over joist or purlins. Variations in the thickness, shape, and depth of the deck can be utilized to meet a variety of loading conditions and spans. The deck can also be fastened to the supporting structure to enable it to act as a diaphragm and provide lateral bracing for the structure.
