The entire system was designed with flexibility in mind. Bay sizes from 15' to 54' may be specified in 6" increments. Eave heights from 10' to 30' are available in 1/8" increments. Single slope, double slope and offset ridge designs are available with a roof slope of ¼:12 to 5/8:12. You may also select tapered columns for maximum economy or straight columns for functionality.
