Description
AST YST 210 175 NB MS CHS - (193.7 x 5.9 mm) - 6 mtr Length is a cold-formed ERW Circular Hollow Section manufactured from YST 210 mild steel fully conforming to IS 1161:2014 (Steel Tubes for Structural Purposes), delivering a minimum yield strength of 210 MPa and tensile strength of 330 MPa for light-to-medium structural, architectural, and utility applications. The 193.7 mm OD × 5.9 mm wall (175 NB) cross-section in 6 m standard lengths provides a large-bore circular section designed for major structural columns, crane structures, and heavy industrial frameworks, with uniform hoop strength, equal bending resistance in all directions, and superior torsional rigidity. Produced by AST PIPES from prime HR coil, each IS-certified tube carries full batch traceability for assured structural performance across all installation types.
