AST PIPES MS RHS AST YST 240 MS RHS - (66 x 33 x 3.2 mm) - 6 mtr Length is a cold-formed electric resistance welded rectangular hollow section conforming to IS 4923:2017, Grade YST 240, with 66 mm depth, 33 mm width, and 3.2 mm wall thickness supplied in standard 6 m lengths. Engineered to deliver a minimum yield strength of 240 MPa and ultimate tensile strength of 360 MPa, this section is purpose-built for medium-duty structural framing, industrial supports, and PEB secondary steel. The rectangular profile provides greater bending strength about the major axis, making it the preferred choice for beam and spanning applications in structural steel fabrication.
