About this detail

Cold-formed steel framing around a wall opening includes built-up headers, boxed jamb studs, and sill tracks anchored to a concrete floor or foundation wall. The built-up header consists of two studs sized per schedule and two tracks matching the wall thickness, screw-fastened together with number ten screws at sixteen inches on center. Jamb studs are formed as a boxed pair, welded together with one-eighth-inch by two-inch long welds at twelve inches on center on each side. The header attaches to king studs with eight minimum screws on each face of the wall at each end, or two inches of one-eighth-inch weld top and bottom on each side. Steel sheet sheathing is attached with edge and field screws per the shear wall schedule.
