Description
The Hariom YST 355 Rectangular Hollow Section Hariom YST 355 MS RHS - (180 x 70 x 5.4 mm) - 6 mtr Length is cold-formed and ERW-welded to IS 4923:2017 specifications, presenting a 180 mm x 70 mm outer dimension with 5.4 mm wall thickness in standard 6 m lengths. With guaranteed mechanical properties of 355 MPa yield and 490 MPa tensile strength, this RHS serves as a reliable structural component for high-strength structural beams, heavy industrial frames, and demanding spanning applications. The closed rectangular cross-section imparts excellent major-axis bending stiffness and torsional rigidity, enabling efficient span and cantilever designs with predictable structural performance.
Key Features:- Grade YST 355 IS 4923:2017 certified RHS with guaranteed mechanical properties
