Conforming to IS 4923:2017 Grade YST 210, the AST PIPES MS RHS AST YST 210 MS RHS - (80 x 40 x 4.5 mm) - 6 mtr Length is a precision cold-formed rectangular hollow section with a 80 mm depth, 40 mm width, and 4.5 mm wall thickness over a 6 m mill length. This ERW-welded tube achieves a minimum yield of 210 MPa and UTS of 330 MPa, making it ideal for general structural, light framing, and furniture-grade applications. 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.
