Architectural Panels Three types of panel profiles are available. The Snap-On Seam and Snap-On Batten panels are designed for use in roofing, fascia, and mansard applications. These panels are desinged for use with a solid substrate and minimum 3:12 roof pitch. These panels are ideal for use on applications where roof transitions are required. The simplicity of the pan design provides superior flatness and allows for easy workability on site. Snap-on panels are installed using non-penetrating clips designed exclusively for these panels. The 3/4" pan leg provides complete protection from capillary action. The Standing Seam roof panel is designed for use in roof areas requiring a structural panel or low slope areas. This panel is suitable for use over structural components or solid substrate to a minimum slope of 1/4" per foot. The panel is fastened with a non-penetrating expansion clip and field seamed with a power driven seamer. Also available by request in rollform 1-piece panels up to 40'-0" long.
