For a more subdued shadow effect, Vicwest’s CL439 panel is an ideal choice. The narrow 1 3/8″ deep ribs are spaced at 13 1/8″ center to center. This pattern creates a subtle refined shadow line which will enhance the appearance of your project. The CL439 profile is also flexible enough for wall or roof applications. Available in 22, 24 and 26 gauge materials and in lengths of up to 37′.
