Common Applications of ISMC 100
ISMC 100 is widely used for purlins in light industrial and agricultural buildings, lintels over openings up to 2 m, secondary beams in mezzanine floors, and cable tray supports in medium-duty electrical installations. Both SAIL and JSW Steel roll ISMC 100 in IS 2062 E250 grade as a standard stocked section across India.
Worked Example
A contractor in Ahmedabad needs 30 lintels of ISMC 100, each 1.5 m long, for a row of shop fronts. Total length = 30 × 1.5 = 45 m. Weight = 45 × 9.2 = 414 kg (0.414 tonnes). At a market rate of ₹57,500 per tonne (Ahmedabad, May 2026), the material cost is approximately ₹23,805 before fabrication and delivery.
