AST PIPES MS SHS AST YST 210 MS SHS - (12 x 12 x 1.8 mm) - 6 mtr Length is a cold-formed electric resistance welded square hollow section conforming to IS 4923:2017, Grade YST 210, with a 12 mm outer dimension and 1.8 mm wall thickness supplied in standard 6 m lengths. Manufactured to deliver a minimum yield strength of 210 MPa and ultimate tensile strength of 330 MPa, this section is purpose-engineered for general structural and light fabrication. Its square geometry and closed cross-section provide excellent torsional rigidity, making it the preferred structural tube for architects and fabricators alike.
