The AST PIPES YST 210 MS SHS AST YST 210 MS SHS - (113 x 113 x 4 mm) - 6 mtr Length is produced through the ERW cold-forming process to meet IS 4923:2017 requirements, offering a 113 mm square section with 4 mm wall thickness and 6 m standard length. With a certified yield strength of 210 MPa and tensile strength of 330 MPa, this hollow section delivers consistent mechanical performance for general structural and light fabrication. The uniform square profile simplifies connection detailing and allows for efficient material utilisation in welded and bolted fabrications.
