The Spark MS RHS Spark YST 310 MS RHS - (120 x 60 x 4.8 mm) - 6 mtr Length is an ERW cold-formed rectangular hollow section produced to IS 4923:2017 Grade YST 310, offering a 120 mm depth and 60 mm width with 4.8 mm wall thickness in standard 6 m lengths. Guaranteeing a minimum yield strength of 310 MPa and UTS of 450 MPa, this section delivers dependable structural performance for heavy structural, high-load bearing frames, and primary spanning applications. Its rectangular hollow form provides superior bending resistance in the dominant load direction while the closed section ensures excellent torsional stiffness.
