AST PIPES YST 240 Rectangular Hollow Section AST YST 240 MS RHS - (130 x 73 x 6 mm) - 6 mtr Length is produced by ERW cold-forming to IS 4923:2017 with a 130 mm x 73 mm cross-section and 6 mm wall thickness in standard 6 m lengths. Delivering a minimum yield of 240 MPa and tensile strength of 360 MPa, this RHS is engineered for medium-duty structural framing, industrial supports, and PEB secondary steel where directional load resistance and weld quality are critical. The four flat external faces and controlled corner radii simplify connection detailing and allow precise fit-up in fabricated beams, frames, and trusses.
