557 Farm Utility Arch-Rib, Quonset

These utility buildings have semicircular (culvert) shape roofs that curve to the ground to form the sides. These buildings have many uses, such as general material, commodity or equipment storage and use lighter gauge materials than their commercial counterparts. Interior modifications can turn them into any one of several uses. Frames are light arch-rib wood with metal (class P) or wood siding or shingles (class D) or self-framing metal Quonset panels (class S). The floors are light concrete, asphalt or dirt at the lower qualities.

Note: Exterior wall choices are not available for this occupancy.
