Produced to IS 4923:2017 Grade YST 310 via the cold-forming ERW process, the AST PIPES MS RHS AST YST 310 MS RHS - (96 x 48 x 5 mm) - 6 mtr Length offers a 96 mm x 48 mm rectangular cross-section with 5 mm wall thickness and 6 m standard length. This hollow section meets minimum yield of 310 MPa and tensile strength of 450 MPa as required for heavy structural, high-load bearing frames, and primary column applications. 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.
