About this detail

The drawing details minimum structural properties, side lap connections, and puddle weld patterns for Type B roof metal decks and Type B cellular acoustical metal decks spanning thirty-six inches with a one-and-a-half-inch depth. Standard decks use eighteen and twenty gauge steel with sheared side lap connections at twenty-four inches on center maximum and five one-half-inch diameter effective puddle welds at each support minimum. Cellular acoustical decks use twenty-twenty gauge steel with sheared side lap connections at twenty-four inches on center maximum and seven one-half-inch diameter effective puddle welds at each support minimum. General notes specify a two span minimum with three preferred, require puddle welds at twenty-four inches on center maximum at supports parallel to corrugations, and define sheared side lap connections as Punchlok by Verco Decking Inc., Deltagrip by ASC Steel Deck, or a preapproved equal.
