Steel Roof Frame CAD Section with Truss Anchor and Concrete Tie Beam

This steel roof frame CAD section drawing presents detailed construction information, including fiberglass shingles over number 15 felt, tin tabbed at 12 inches on center over 1 by 2-inch CDX plywood sheathing. The roof structure is anchored with one 8d nail at 4 inches on center to pre-engineered roof trusses spaced at 24 inches on center. Trusses are secured using Simpson HETA 20 anchors connected to an 8-inch by 16-inch concrete tie beam reinforced with four number 5 rods running continuously through the structural beam. The drawing clearly explains the roof structural assembly and fastening configuration required for stable roof installation.
