Produced to IS 4923:2017 Grade YST 240 by the cold-forming ERW process, the AST PIPES MS SHS AST YST 240 MS SHS - (38 x 38 x 1.2 mm) - 6 mtr Length offers a 38 mm square section with 1.2 mm wall thickness and 6 m standard length. This hollow section meets the minimum yield strength of 240 MPa and tensile strength of 360 MPa as required for medium-duty structural and industrial framing. The precisely formed corners and consistent wall thickness of this square tube ensure uniform stress distribution under multi-directional loading, offering superior performance over open sections of equivalent weight.
