Depending on its size, A500 structural pipe is used in construction, heavy equipment, agricultural, machinery, fabrication, and general structural purposes. In construction, they are often used as support beams or columns. In heavy equipment manufacturing, they are used in the construction of machineries such as tractors and excavators. In agriculture, they are often used in the construction of irrigation systems. In fabrication, they are commonly used to create sections for steel beams and pillars. As a result, ASTM A500 structural pipes have a wide range of applications in many industries. ASTM A500 tubing comes in four grades: Grade A, Grade B, Grade C, and Grade D. Each grade has specific chemical requirements as well as different mechanical property requirements that must be met in order to be considered ASTM A500-compliant. 


ASTM A500 Carbon Steel Structural Tubing has various advantages that make it a popular building material for structural load-bearing applications. Some of the most noticeable advantages that A500 Carbon Steel Structural Tubing offers are:

  • Excellent weldability

  • Good machinability

  • Can be cold worked

  • Aesthetically pleasing
