Combining equal-axis strength with precision circular geometry, the AST YST 240 225 NB MS CHS - (244.5 x 5.9 mm) - 6 mtr Length from AST PIPES is a cold-formed ERW CHS in YST 240 structural steel conforming to IS 1161:2014 (Steel Tubes for Structural Purposes). The 244.5 mm OD × 5.9 mm wall (225 NB) section in 6 m lengths is a large-bore circular section designed for major structural columns, crane structures, and heavy industrial frameworks achieving an optimal balance of axial capacity, torsional resistance, and fabrication ease for industrial frameworks, mezzanine columns, portal frames, and architectural exposed tubes. With minimum yield of 240 MPa and tensile of 360 MPa, this IS-certified tube meets the performance demands of medium-duty structural, industrial, and architectural fabrication with full traceability.
