About this detail

Framing requirements for small openings in a non-composite metal deck perpendicular to the deck span. Openings less than 5 inches in diameter cutting no more than one web require no additional framing. Openings positioned with an edge within 3 inches of steel framing below also require no additional framing. When framing is required, C6x10.5 channels run below the deck with L3x3x1/4 angles attached by vertical legs. Specific dimensioning criteria govern spacing between multiple openings labeled A, B, D1, and D2 to determine single versus grouped opening framing rules.
