The Hariom MS RHS Hariom YST 355 MS RHS - (145 x 82 x 5.4 mm) - 6 mtr Length is an ERW cold-formed rectangular hollow section produced to IS 4923:2017 Grade YST 355, offering 145 mm depth and 82 mm width with 5.4 mm wall thickness in standard 6 m lengths. Guaranteeing minimum yield of 355 MPa and UTS of 490 MPa, this section delivers dependable structural performance for high-strength structural beams, heavy industrial frames, and demanding spanning applications. Its rectangular hollow form provides superior bending resistance in the dominant load direction while the closed section ensures excellent torsional stiffness in frame and support structures.
