ASTM A500 Rectangular Pipe is a premium US standard carbon structural steel rectangular pipe, available in Grade A, B and C, produced via cold-forming or welded processes for diverse structural needs. It features high yield and tensile strength, excellent weldability, machinability and cold workability for flexible on-site fabrication and customization. The rectangular cross-section delivers superior structural rigidity and load-bearing capacity, paired with precise dimensional tolerance and uniform wall thickness. Performing stably under normal temperature and pressure, it’s cost-effective and versatile, serving as a core structural pipe for industrial and civil engineering with varied sectional demands.
