AST PIPES YST 210 Rectangular Hollow Section AST YST 210 MS RHS - (66 x 33 x 4 mm) - 6 mtr Length is produced by ERW cold-forming to IS 4923:2017 with a 66 mm x 33 mm cross-section and 4 mm wall thickness in standard 6 m lengths. Delivering a minimum yield of 210 MPa and tensile strength of 330 MPa, this RHS is engineered for general structural, light framing, and furniture-grade applications 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.
