AST PIPES presents the Grade YST 240 MS RHS AST YST 240 MS RHS - (90 x 60 x 3 mm) - 6 mtr Length, an IS 4923:2017-compliant ERW cold-formed rectangular hollow section with 90 mm depth, 60 mm width, 3 mm wall thickness, and 6 m standard length. Certified to achieve a minimum yield of 240 MPa and UTS of 360 MPa, this section is optimised for medium-duty structural framing, industrial supports, and PEB secondary steel requiring directional bending strength and dimensional accuracy. The rectangular hollow profile enables internal service routing while delivering full structural functionality as beams, lintels, and spanning members in steel construction.
