The AST PIPES YST 210 MS RHS AST YST 210 MS RHS - (40 x 25 x 1.4 mm) - 6 mtr Length is manufactured through the ERW cold-forming process to comply with IS 4923:2017, featuring a 40 mm x 25 mm rectangular cross-section with 1.4 mm wall thickness in 6 m standard lengths. With a guaranteed yield strength of 210 MPa and tensile strength of 330 MPa, this hollow section provides reliable mechanical performance for general structural, light framing, and furniture-grade applications. Its asymmetric rectangular geometry delivers enhanced major-axis bending capacity, optimising material efficiency in beam and lintel structural applications.
