The structural strength of steel pipes depends on factors such as the material type (such as carbon steel, stainless steel, high-strength steel), the manufacturing process (seamless, welded pipe), and whether it is a composite structure (such as steel tube concrete). In high-rise buildings and bridges, by pouring concrete into the steel pipe to form a steel tube concrete composite structure, the strength and rigidity of the steel pipe can be significantly improved, and the local buckling of the steel pipe can be limited, thereby improving the load-bearing capacity of the entire structure.

Manufacturing Process: The manufacturing process and internal quality of seamless steel pipes, including hot-rolled, cold-rolled, cold-drawn, and extruded pipes, as well as welded pipes (such as longitudinally welded and spirally welded pipes), affect the final structural strength and performance.

A500 Steel Pipe Grade B and Grade C are used for general structural purposes, such as columns, beams, and other load-bearing applications. Grade B has a minimum yield strength of 46,000 psi (315 MPa) and a minimum tensile strength of 58,000 psi (400 MPa).
