Conforming to IS 4923:2017 Grade YST 210, the AST PIPES MS SHS AST YST 210 MS SHS - (135 x 135 x 5.4 mm) - 6 mtr Length is a precision cold-formed square hollow section featuring 135 mm outer dimensions and 5.4 mm wall thickness across a 6 m mill length. This ERW-welded section achieves a minimum yield of 210 MPa and UTS of 330 MPa, making it reliable for general structural and light fabrication. The symmetric closed profile enhances stiffness-to-weight ratio and enables clean, consistent welds on all four faces of the section.
