AST PIPES YST 240 Square Hollow Section AST YST 240 MS SHS - (12 x 12 x 1.4 mm) - 6 mtr Length is manufactured by ERW cold-forming to IS 4923:2017, with a 12 mm square cross-section, 1.4 mm wall thickness, and standard 6 m cut length. Delivering 240 MPa yield and 360 MPa tensile strength, this SHS is designed for medium-duty structural and industrial framing where dimensional accuracy and weld quality are paramount. Its four flat external faces offer maximum bearing area for connections, gussets, and base plates in structural steel assemblies.
