Specification

Structural pipe is steel pipe which has not been pressure tested which is used in many applications across various industries. Structural steel pipe sizes range from 1/2″ to 48″ outer diameter and it is made from carbon, stainless, or galvanized steel. Structural pipe is also referred to as structural tubing.


Structural steel pipe is a great choice in construction, agricultural, and recreational settings. It is ideal for creating sturdy and reliable fence building frameworks, ensuring safety and security for livestock and property. For cattle guards and horse arenas, structural steel pipe provides the necessary strength and durability to withstand heavy use and environmental stress. In feedlots, the structural integrity of our pipe ensures the safe containment and management of livestock. Structural pipe is excellent for constructing robust frameworks in recreational facilities, sports complexes, and more, underscoring their utility in various sectors.
