Post-Frame Construction

Construction
Throughout history, post-and-beam, or post-frame construction, concepts and design have been used as the model for constructing rural buildings. Previously referred to as pole barns, this construction method revolves around the strategic placement of large, widely spaced posts or columns.
Since the turn of the century, the simplicity and durability of this type of construction has made it ideal for a range of structures, from agricultural and residential to commercial and industrial buildings. And typically, Southern Pine is the preferred wood!
Post-frame buildings are known for their ability to withstand severe weather conditions. Engineers have used modern technology to update these designs, which has extended the use of post-frame construction to commercial buildings. Common commercial applications include auto dealerships and repair shops, retail stores, office buildings, and churches.
Key features of post-frame projects include:
- Vertical posts or columns: At the heart of post-frame construction are vertical posts or columns strategically positioned at regular intervals. These elements serve as the primary structural support for the entire building.
- Wide spacing of posts: Setting itself apart from traditional framing methods, post-frame construction incorporates wide spacing between posts. This not only reduces the overall material requirements but also allows architects and builders greater flexibility to design and use the interior space.
- Trusses or purlins for roof support: Unlike traditional rafters, post-frame buildings leverage roof trusses or purlins for support. This approach evenly distributes the weight of the roof and creates additional open space within the structure.
- Simple foundation: Depending on soil conditions and local building codes, posts may either be embedded directly into the ground or anchored to a concrete slab, streamlining the construction process.
- Cost-effectiveness: Simplicity is the key in post-frame construction. The reduced need for materials makes this method an economical choice that doesn’t compromise structural integrity when compared to traditional building methods.
- Quick construction: The combination of wide post spacing and pre-engineered components, such as trusses, ensures a faster assembly process, making it an appealing option for those seeking timely project completion.
