About this detail

Overhead support framing for a folding door system is installed beneath a concrete-filled metal deck and steel beam floor assembly. An MC18x42.7 channel acts as the primary carrier, suspended by hanger brackets and rods provided by the door supplier. For lateral stability, L3x3x1/4 kickers and HSS5x5x3/16 hollow structural section braces are welded to the steel beams using typical three-sixteenths-inch and quarter-inch fillet welds. Beam web stiffeners composed of L6x4x1/4 angles are attached to each side of the HSS members. Additional connection conditions feature L4x4x3/8 angles where channels frame into deeper grid beams.
