A pole barn under construction. A pole barn under construction. Pole framing or post-frame construction (pole building framing, pole building, pole barn) is a simplified building technique adapted from the labor-intensive traditional timber framing technique. It uses large poles or posts buried in the ground or on a foundation to provide the vertical structural support and girts to provide horizontal support.
A pole barn is a structure that's supported by poles set in the ground and anchored by concrete. Poles support the roof, and walls are optional. No foundation is required, and finished floors are also optional. Pole barns can be built to any size. The framing is horizontal to the posts, ensuring a sturdy and reliable structure. The posts and frame of pole barns are made of wood. Metal or wood siding can be used. Roofs typically are made from galvanized steel, although shinglesÂ­ also can be used [source: Burch].
