WHAT IS POST FRAME?
Post-frame buildings typically feature large, solid-sawn wood posts or laminated columns instead of the 2×4” studs found in many wood-frame buildings. Loads are transferred to the ground through the posts, which are typically embedded in the ground or surface-mounted to a concrete or masonry foundation.
Many people simply think of a “pole barn” when they try to imagine a post-frame structure. Although the post-frame design was originally perfected by engineers for large agricultural buildings, the design has proven so efficient and versatile that barns now constitute only a fraction of the post-frame industry. However, post-frame remains the obvious choice for horse barns, riding arenas, machinery storage, sheds and most other agricultural buildings.
Round “poles” are no longer used in post-frame construction; rot and insect-resistant pressure-treated square posts, nail-laminated or glue-laminated wood columns, and new types of materials are used instead. Laminated columns may also be engineered to build large, arching structural members that are ideal for church sanctuaries and other open timber interiors.
Due to the application of modern structural engineering principles and stress testing methods, post-frame technology is now recognized as a truly significant advancement in the centuries-old art of wood frame construction. Post-frame is now the construction method of choice for any number of different commercial, retail, industrial, residential, religious and public building needs.
