DIFFERENCE BETWEEN PIPE AND POST


In structural and construction terminology, the terms "post" and "pipe" refer to different structural elements with distinct characteristics and applications:

Post


-A post typically refers to a vertical structural member that is sturdy and designed to support loads or provide structural integrity. Posts are commonly used in construction to bear the weight of beams, joists, or other structural elements, transferring these loads to the foundation. They are usually larger in size and are often made of solid wood, steel, or concrete.

Pipe


-A pipe, on the other hand, is a tubular-shaped hollow section generally designed for the transportation of fluids or gases. In construction, pipes are more often used for plumbing, drainage, or conveying substances from one place to another. They come in various materials such as steel, PVC (Polyvinyl chloride), copper, or other metals or plastics depending on the intended use.

While both posts and pipes are cylindrical in shape, their primary functions, construction materials, and applications are notably different. Posts are typically utilized for structural support, while pipes are commonly employed for fluid or gas transportation and distribution systems.


If a vertical member weight falls below 300 pounds according to OSHA regulations, it is referred to as a "post." However, if the weight exceeds 300 pounds, it is categorized as a "column."


COMPARISON BETWEEN ASTM A500 & A1085


ASTM A500 has been the preferred material specification in the United States for cold formed, welded carbon steel hollow structural sections (HSS) since the late 1970s. In April of 2013, a new material specification, ASTM A1085, was released for steel tubes used in structural applications.
