The AST PIPES YST 240 MS SHS AST YST 240 MS SHS - (60 x 60 x 5.4 mm) - 6 mtr Length is produced through the ERW cold-forming process to meet IS 4923:2017 requirements, offering a 60 mm square section with 5.4 mm wall thickness and 6 m standard length. With a certified yield strength of 240 MPa and tensile strength of 360 MPa, this hollow section delivers consistent mechanical performance for medium-duty structural and industrial framing. The uniform square profile simplifies connection detailing and allows for efficient material utilisation in welded and bolted fabrications.
