Conforming to IS 4923:2017 Grade YST 240, the AST PIPES MS RHS AST YST 240 MS RHS - (100 x 50 x 3.2 mm) - 6 mtr Length is a precision cold-formed rectangular hollow section with a 100 mm depth, 50 mm width, and 3.2 mm wall thickness over a 6 m mill length. This ERW-welded tube achieves a minimum yield of 240 MPa and UTS of 360 MPa, making it ideal for medium-duty structural framing, industrial supports, and PEB secondary steel. The closed rectangular cross-section combines high bending stiffness in the primary loading direction with excellent torsional rigidity, enabling efficient structural spanning and framing solutions.
