Produced to IS 4923:2017 Grade YST 355 via the ERW cold-forming process, the Hariom MS RHS Hariom YST 355 MS RHS - (200 x 100 x 7 mm) - 6 mtr Length offers a 200 mm x 100 mm rectangular cross-section with 7 mm wall thickness and 6 m standard length. This hollow section meets minimum yield of 355 MPa and tensile strength of 490 MPa as required for high-strength structural beams, heavy industrial frames, and demanding spanning 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.
