Outside dimensions and wall thickness as per IS 4923:1997. Cross-sectional area and mass per metre from IS 4923:1997 Table 4. Sectional properties calculated from IS 4923 geometry. x–x axis is about the height (H) direction; y–y axis is about the width (B) direction. RHS is not doubly symmetric — Ixx ≠ Iyy. Mass tolerance: ±6% per individual piece as per IS 4923:1997 Clause 10.
Common Applications of 60×40×2.5 RHS
60×40×2.5 RHS is used in canopy purlins and secondary framing and related structural framing. The rectangular hollow profile concentrates more material in the plane of bending, giving higher Iyy about the strong axis compared to an equal SHS. Tata Structura YST 240 supply this section in YST 310 and YST 355 grade to IS 4923:1997 from stock at major steel distributors.
Worked Example
A fabricator in Coimbatore needs 16 purlins of 60×40×2.5 RHS, each 3.0 m long, for a canopy purlins and secondary framing. Total length = 16 × 3.0 = 48.0 m. Weight = 48.0 × 3.65 = 175.2 kg. At a market rate of ₹65,000 per tonne (May 2026), material cost is approximately ₹11,388 before cutting and fabrication.
