Primary Framing

Clear Span

Clear Span structures’ reliable design makes it one of the strongest and most dependable building frames available and allows you to build unobstructed interior structures of any size. Common uses for clear span framing include aircraft hangars, arenas, indoor sports facilities, manufacturing facilities, warehouses, offices, and retail stores.


Multi-span frames are frequently used for buildings that allow for interior columns. Large open floor spaces provide easy movement of forklifts by using the minimum number of columns. Multi-Span frames are well-suited for large buildings with low-sloped roof designs. Common uses include manufacturing plants, warehouses, truck terminals, and retail stores.


Primarily used for the expansion of buildings, lean-to frames provide cost-effective additional space for your structure. A lean-to frame typically has a single slope profile (no ridge) and straight sidewall columns. It must be supported by attachment to another frame.
