The AST PIPES YST 240 MS RHS AST YST 240 MS RHS - (75 x 25 x 3 mm) - 6 mtr Length is manufactured through the ERW cold-forming process to comply with IS 4923:2017, featuring a 75 mm x 25 mm rectangular cross-section with 3 mm wall thickness in 6 m standard lengths. With a guaranteed yield strength of 240 MPa and tensile strength of 360 MPa, this hollow section provides reliable mechanical performance for medium-duty structural framing, industrial supports, and PEB secondary steel. Its asymmetric rectangular geometry delivers enhanced major-axis bending capacity, optimising material efficiency in beam and lintel structural applications.
