The AST PIPES YST 240 Square Hollow Section AST YST 240 MS SHS - (113 x 113 x 4.5 mm) - 6 mtr Length is cold-formed and ERW-welded to IS 4923:2017 specifications, presenting a 113 mm outer dimension with 4.5 mm wall thickness in standard 6 m lengths. With guaranteed mechanical properties of 240 MPa yield and 360 MPa tensile strength, this SHS serves as a reliable structural component for medium-duty structural and industrial framing. The closed square cross-section imparts excellent torsional and bending stiffness, enabling span and cantilever structural designs with minimal deflection.
