Curveline's metal panel conveyor covers turns standard metal building panels into rigid, self-supporting covers that may be used wherever covered conveyor systems are required for weather protection or air pollution control. Curveline can create covers for 50 different exposed fastener panels. The company recommends a minimum of 24-gauge steel in ?-inch to 1½-inch panel depths for curved cover applications. Unfinished galvanized steel is the most common substrate, but pre-painted panels are optional. Covers are crimp-curved into 180-degree clear spans without the need for structural framing. In addition to 180-degree applications, panels can be curved into any radii and angles of curvature using chord width and height dimensions provided by the customer. Based on a 100-mph wind factor, a single 24-gauge, grade-D (50 ksi) steel panel can be curved to form spans ranging from 6 feet 1 inch up to 11 feet 9 inches, depending on the profile. With an 80-mph wind factor, the clearspan range is 7½ feet to 14 feet 8 inches. Curveline Inc.
