About this detail

A bent plate closure at a steel roof deck overhang supported by a structural steel beam. A bent plate with a minimum bend radius of 1.5 times the plate thickness is welded to the steel beam and metal roof deck. Plate thickness varies based on overhang dimension, using a 3/16-inch plate for overhangs under 6 inches, a 1/4-inch plate for overhangs between 6 and 10 inches, and a 5/16-inch plate for overhangs between 10 and 12 inches. A 3/8-inch bent plate may be used for overhangs under 16 inches. Fillet welds of 3/16-inch size are applied at a 12-inch typical spacing. The assembly maintains a three-quarter-inch minimum gap at brick veneer, curtain wall, or steel stud framing, and a one-and-a-quarter-inch minimum gap at precast framing with bypass framing coordinated per architectural drawings.
