Pole Barns, or post frame buildings are one of the least expensive ways to configure basic vertical steel columns that support only a roof and walls. They are roof cladded with a heavy gauge steel panel that are fastened with a corrosion resistant self drilling commercial type screw. Often, canopy styles, which have a roof only, are used for recreational open areas, equipment storage, and storing many types of commodities. Pole Barns allow for very large spans, giving plenty of room for whatever your use may be. Typical roof shape choices are double sloped and single slope. 770-781-8279 larry@lthsteelstructures.com
