Sixteen-gauge three-inch metal decking bears on a welded L3x3x1/4 angle support sloped at one-quarter inch per foot. Eighteen-gauge three-inch metal decking rests on an L4x4x1/4 angle connected to a C15 channel spaced at forty-eight inches on center. A quarter-inch by three-inch by zero-foot-eight-inch plate welded to the channel connects to the angle using two five-eighth-inch bolts on each plate, with typical quarter-inch fillet welds.
