7.2 Panel

The 7.2 Panel is a deeper-ribbed profile in the PAC-CLAD | Petersen exposed-fastener range. Its name comes from its rib spacing of 7.2 inches. It is used on roofs and walls as one of the exposed-fastener metal roof panels.

The panel is 36 inches wide (nominal) and 1-1/2 inches high. Ribs are 1-1/2 inches high at 7.2 inches on center, with crests 2 inches wide and valleys 2 inches wide. Installed coverage is 36 inches for both roofing and wall use.

• Width: 36 in. nominal
• Rib height: 1-1/2 in.
• Rib spacing: 7.2 in. on center
• Crest and valley width: 2 in. each

Available in .032, .040 and .050 aluminum, and 24 or 22 gauge steel. Galvalume Plus is an option. Precut lengths start at 5 feet, and maximum lengths are 30 feet in steel and 22 feet in aluminum.

The panel is tested under ICC ES-5839. Florida Building Product Approvals for exposed-fastener panels apply. The 7.2 panel is made at the Tyler, TX factory in addition to other plants.

The finish is a Kynar 500 or Hylar 5000 fluorocarbon with a 35-year non-prorated warranty. Matching screws and rivets and closure strips are available.

The 7.2 Panel is a lappable, structural ribbed panel that is fastened directly to the substrate and has an overlapping sidelap. Fasteners use combination steel and EPDM washers and penetrate the girt or purlin by 1 inch. Sidelap and flashing screws are #14 HHA x 3/4 inch sheet metal stitch screws at 12 inch centers. Closures are pre-molded polyethylene to suit the rib shape. Trim is press-broken in 10 to 12 foot lengths with factory-welded miters.

The coating has a topside film of 0.70 to 0.90 mil over a 0.25 to 0.3 mil prime coat, and a 0.25 mil underside primer, meeting AAMA 621.

The 7.2 Panel is also covered by the perforated exposed-fastener guide specification, in .032, .040 and .050 aluminum painted one side. Round hole patterns run from 1/8 inch holes on .324 inch staggered centers (13.5 percent open area) to 3/8 inch holes on 9/16 inch centers (40 percent open area). Perforated panels carry a 20-year finish warranty period and a longer lead time.
