This structural framing plan details steel channel headers and wide-flange framing members around medium-sized deck openings ranging from two to six feet in width. C6x8.2 channel headers span between W10x12 beams and framing members sized per plan to support floor or roof cutouts. Dimensions indicate maximum edge distances and placement tolerances for deck reinforcement. The contractor must coordinate all opening sizes and locations with architectural and mechanical plans.
