The AST PIPES MS RHS AST YST 240 MS RHS - (200 x 100 x 6 mm) - 6 mtr Length is an ERW cold-formed rectangular hollow section produced to IS 4923:2017 Grade YST 240, offering a 200 mm depth and 100 mm width with 6 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 in frame and support structures.
