Curveline Inc. now offers 3-inch trapezoidal standing-seam roofing panels for commercial and residential applications. The curved panels have a leak-proof design to overcome water-infiltration problems associated with shallower, flat-pan (vertical leg) curved standing seam. Three-inch-deep standing-seam panels may be curved into radii from 30 feet to 350 feet using Curveline's proprietary method. Panel widths of 12-, 18- and 24-inches may be curved with a maximum panel length of approximately 34-feet.
