The AST PIPES YST 240 Rectangular Hollow Section AST YST 240 MS RHS - (25 x 13 x 1 mm) - 6 mtr Length is cold-formed and ERW-welded to IS 4923:2017 specifications, presenting a 25 mm x 13 mm outer dimension with 1 mm wall thickness in standard 6 m lengths. With guaranteed mechanical properties of 240 MPa yield and 360 MPa tensile strength, this RHS serves as a reliable structural component for medium-duty structural framing, industrial supports, and PEB secondary steel. The closed rectangular cross-section imparts excellent major-axis bending stiffness and torsional rigidity, enabling efficient span and cantilever designs with predictable structural performance.
