Post
Definition
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.
Structural & construction notes
Common types of posts include timber posts used in residential framing, steel posts for industrial or heavy-duty applications, and concrete posts often used for foundations or fencing. Architectural variations include classic columns, decorative pillars, and specialized structural members like king posts or queen posts used in roof trusses. Common materials include timber, steel, and concrete. High-durability materials like steel and concrete have higher initial costs but offer lower long-term maintenance and longer lifespans. Affordable options like timber reduce upfront investment but require more frequent maintenance and have shorter service lives due to vulnerability to pests and rot.
