The AST PIPES MS SHS AST YST 240 MS SHS - (113 x 113 x 3.2 mm) - 6 mtr Length is an ERW cold-formed square hollow section produced to IS 4923:2017 Grade YST 240 with outer dimensions of 113 mm and a wall thickness of 3.2 mm. Supplied in standard 6 m lengths, this section guarantees minimum yield strength of 240 MPa and tensile performance of 360 MPa for dependable medium-duty structural and industrial framing. The biaxially symmetric square profile distributes compressive and bending loads equally on all axes, making it a versatile choice for structural column and framing applications.
