About this detail

Cutting and reinforcing guidelines apply to openings in metal deck floor assemblies supported by steel beams below. Small holes less than six inches in diameter cutting no more than one web require no reinforcement. Openings near steel framing within six inches also omit reinforcement. Grouped openings utilize L1 3/4x1 3/4x1/4 angles placed on top of the deck and extending three deck webs past the opening. Spacing rules dictate whether closely spaced openings are treated as a single large opening based on dimensions A and B relative to D1 and D2.
