Common Applications of 40×40×2.5 SHS

40×40×2.5 SHS is used in light gate and related structural framing. The square hollow profile provides equal stiffness about both axes, making it well suited for columns, posts, and members loaded in biaxial bending. Tata Structura YST 240 supply this section in YST 310 and YST 355 grade to IS 4923:1997 from stock at major steel distributors across India.

Worked Example

A fabricator in Jaipur needs 8 gate frames of 40×40×2.5 SHS, each 3.0 m long, for a light gate. Total length = 8 × 3.0 = 24.0 m. Weight = 24.0 × 2.87 = 68.9 kg. At a market rate of ₹65,000 per tonne (May 2026), material cost is approximately ₹4,477 before cutting and fabrication.
