ASTM A500 Tubing is primarily made from carbon steel, featuring a carbon content of up to 0.26%, manganese up to 1.35%, and small amounts of phosphorus, sulfur, and copper. It comes in Grades A, B, C, and D, each providing different levels of mechanical strength. For instance, Grade B has a minimum yield strength of 290 MPa and a tensile strength of 400 MPa, while Grade C offers even higher specifications. This tubing is known for its excellent weldability, smooth surface finish, and consistent wall thickness. Its mechanical properties make it a great fit for applications that demand strength, reliability, and formability in structural contexts.

ASTM A500 Tubing is a popular choice in structural and architectural applications thanks to its strength, versatility, and cost-effectiveness. You’ll often find it in building frames, columns, trusses, bridges, and support structures in both commercial and industrial construction. It’s also used in the production of trailers, agricultural equipment, and machinery. The tubing’s uniformity and polished finish make it perfect for aesthetic and exposed applications as well. Its ability to handle load-bearing stress, combined with ease of fabrication and welding, makes ASTM A500 Tubing a go-to option for engineers and fabricators working on both light and heavy construction projects.
