What's in a name? Well, when it comes to a pole building or a shop - the type of construction.
A pole building is made with poles set approximately 36" into the ground (below the frost line), and then purlins are framed between the poles. This creates a downward shear force and a building. Metal is the most commonly used material for a pole building, but the building can also be sheeted with 4'x8' sheets of OSB or plywood, and can be conventionally sided. Pole buildings can have a metal or composite shingle roof, and can be as plain or as fancy as you want. Concrete is poured between the bottom treated purlins between 4-6" (depending on the use or owner preference). Pole buildings are one of the most economical methods of putting up a building, with basic buildings starting at $27 per square feet (with concrete).
