The Spark MS RHS Spark YST 240 MS RHS - (260 x 180 x 5 mm) - 6 mtr Length is an ERW cold-formed rectangular hollow section produced to IS 4923:2017 Grade YST 240, offering a 260 mm depth and 180 mm width with 5 mm wall thickness in standard 6 m lengths. Guaranteeing a minimum yield strength of 240 MPa and UTS of 360 MPa, this section delivers dependable structural performance for medium-duty structural framing, industrial supports, and PEB secondary steel. Its rectangular hollow form provides superior bending resistance in the dominant load direction while the closed section ensures excellent torsional stiffness.
