AL Series, Zn Series, CL Series, and ACM Series panels can be manufactured in such a way that the face exists on a plane that does not parallel the mounting surface and the sides of the panel taper from small to large. Panels can be tapered in one or two directions, and can be as large or as small as the panel system allows. By placing these tapered panels in different configurations, many unique facade options are possible. This photo shows rectangular AL Series aluminum panels, which taper in two directions to create a series of divits across the facade of a California high school.
