Products: The project used 8,100 feet of Oklahoma City-based Flex-Ability Concepts Flex-C Angle and 15,000 feet of 16- and 20-gauge Flex-C Trac in 3 5/8- and 6-inch widths to frame the rotunda and front façade, as well as to create interior curves and radiuses.
Fine Points: The 6-story, 183,000-square-foot building is capped with a rotunda that emits a beacon visible at night across half the city. The product involved many radiuses weaving together. Numerous large radiuses had to be laid out off of a grid. The tracking includes a Hammer-Lock feature, which allows the shaped track to be held in place by hammering down tabs in each link instead of securing the track with screws.
