A post is a primary vertical structural element, typically made of timber, metal, or stone, used to support loads from beams, girders, roofs, or floors and transfer them to the foundation or ground. While functionally similar to a column or pier, posts are often distinguished by their smaller scale and square or rectangular profiles, and they serve as the fundamental upright components in post-and-beam, post-and-lintel, and timber-frame construction. Beyond their essential role in maintaining a building's structural integrity and stability, posts are versatile elements used in various applications, including porch and deck supports, fencing, and pergolas, where they can be left exposed to contribute to the architectural character and aesthetic of a space.
