A truss includes a plurality of truss members, each truss member formed from a unitary folded blank of sheet metal to create a main panel, and proximal and distal flanges and a horizontal panel each extending perpendicularly from the main panel, the proximal flange of a first truss member is connected to the distal flange of a second truss member to form a truss. In one embodiment employing trusses formed of folded sheet metal, a plurality of interconnected truss modules, each truss module including a plurality of truss members, forms a plurality of oppositely extending horizontal flanges that collectively present the top and bottom surfaces of a cantilevered canopy.
