One and one-half inch deep metal roof decking with a six-inch pitch and a three-foot sheet width utilizes five distinct fastener patterns, labeled 36/4 through 36/11, to accommodate varying structural requirements. Fasteners are installed at perimeter supports parallel to the deck span at a maximum spacing of four inches on center for patterns 36/9 through 36/11, and six inches on center for patterns 36/4 through 36/7. Specific fastener types and attachment patterns must be verified against the project roof framing plans.
