Post-frame construction is ideal for warehouses, churches, auto repair shops, fire stations, bus companies, and other commercial structures that require open spaces. Post-frame buildings are sometimes called post-and-beam buildings.

The design concept is simple and offers flexibility, which makes it popular among architects, engineers, and building designers. The features of post-frame design include heavy posts, supporting columns or posts, and roof trusses. Depending on the spacing of the posts and trusses, wall girts and roof purlins may be required to attach and support wall and roof sheathing.
