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 50×25×2.5 RHS
50×25×2.5 RHS is used in light handrail and shelf 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. APL Apollo 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 Chennai needs 20 handrail sections of 50×25×2.5 RHS, each 2.0 m long, for a light handrail and shelf framing. Total length = 20 × 2.0 = 40.0 m. Weight = 40.0 × 2.67 = 106.8 kg. At a market rate of ₹65,000 per tonne (May 2026), material cost is approximately ₹6,942 before cutting and fabrication.
