A deck assembly includes a plurality of deck panels in a side-by-side and end-by-end relationship. The deck panels include a support having a pair of opposed sides, opposed ends, and an arcuate portion having a convex surface and an opposite concave surface between and connected to a pair of spaced extensions. An elongated structural cover is positioned over the arcuate portion and attached to the support. The cover provides structural stability to the deck panel. Optionally, layers of insulation or a layer of concrete overlays the structural cover and exposed portions of the support between the covers. Optionally, the deck assembly can be made of acoustical deck panels.
