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.
Pole barn/post frame trusses are what hold most pole barn/post frame buildings together as a structure providing strength and durability. We offer a variety of roof truss sizes ranging from 20' to 40' as well as framing and wall columns that range from 10' to 46' in height. Use our tools and accessories to put your project together. Give your pole barn/post frame building the finishing touch with durable composite gradeboard from Midwest Manufacturing.
