Common Applications of 75×75×3 SHS
75×75×3 SHS is used in light industrial shed 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 and APL Apollo 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 Ludhiana needs 10 shed columns of 75×75×3 SHS, each 6.0 m long, for a light industrial shed. Total length = 10 × 6.0 = 60.0 m. Weight = 60.0 × 6.69 = 401.4 kg. At a market rate of ₹65,000 per tonne (May 2026), material cost is approximately ₹26,091 before cutting and fabrication.
