About this detail

A typical small opening in a metal deck is supported by a 14 gauge steel plate placed below the deck. The plate extends two inches into the nearest full low flute on each side, with a maximum opening size of 10 inches and minimum clearances of six inches. Number 10 sheet metal screws are spaced at three inches equally on each low flute on both sides. Interrupted reinforcement must be relocated to both sides of the opening, and closures or sleeves are provided as required for placing concrete.
