Framing configurations around openings in steel deck assemblies for varying opening dimensions labeled as D. The smallest openings utilize L2x2x1/4 angles below the deck with 5/8-inch diameter fasteners. Medium openings from 24 inches to 72 inches use C3x4.1 channel framing members. Larger openings from 72 inches up to 98 inches incorporate heavier C4x5.4 channel framing members. Deck flutes are adjusted as required to achieve proper bearing on the surrounding channel framing.
