About this detail

Metal deck openings are reinforced with angle sections placed on top of the deck and extending three deck webs past the opening as typical. Holes less than six inches in diameter cutting no more than one web do not require reinforcement, nor do openings within six inches of steel framing below the deck. Spacing criteria define single versus grouped openings based on dimensions 'A' and 'B' relative to opening diameters 'D1' and 'D2'.
