Nellis Air Force Base and Nevada Air Combat Command Department of the U.S. Air Force, Las Vegas

Ingenium Mechanical Design Group LLC specified standing seam panels for gabled roofs on six flight line canopies owned by Nellis Air Force Base and Nevada Air Combat Command Department of the U.S. Air Force in Las Vegas. The metal panels replaced fabric enclosures, which required repairs and replacement due to damage from daylight and wind. The structures’ main framework was removed and replaced as needed.

PVB Fabrications Inc., general contractor and installer for the project, installed 140,400 square feet of McElroy Metal Inc.’s Masterlok-FS standing seam roof system in Travatan. The panels were produced with a 24-inch minimum width and 22-gauge minimum of galvanized steel. They have a factory-applied bead of elastomeric caulking.

The standing seam panels are continuous from roof ridge lines to drip edges. They are secured to steel purlins and roof beams with metal floating clips that allow for expansion and contraction during temperature changes. McElroy Metal supplied the purlins and PVB Fabrications fabricated frames and columns. The roof panels extend 2 feet beyond girders to provide overhanging eaves, and the gutters have EPDM lining.

The flight line canopies have overhead and side-mounted lighting, powered by underground electricity and outlets. The project was completed October 2017.
