Produced to IS 4923:2017 Grade YST 240 via the cold-forming ERW process, the AST PIPES MS RHS AST YST 240 MS RHS - (100 x 50 x 4.5 mm) - 6 mtr Length offers a 100 mm x 50 mm rectangular cross-section with 4.5 mm wall thickness and 6 m standard length. This hollow section meets minimum yield of 240 MPa and tensile strength of 360 MPa as required for medium-duty structural framing, industrial supports, and PEB secondary steel. The precisely formed rectangular geometry maximises depth-to-weight efficiency, allowing designers to achieve greater spans and reduced deflections compared to equivalent open structural sections.
