Common Applications of ISMB 200
ISMB 200 is a go-to section for mezzanine primary beams, industrial shed rafters, and staircase stringers requiring spans of 3–5 m. Its 100 mm flange width makes welded and bolted connections straightforward. SAIL, Tata Steel, and JSW Steel carry ISMB 200 as permanent stock in IS 2062 E250 and E300 grades.
Worked Example
A steel fabricator in Mumbai requires 20 floor beams of ISMB 200 each 5.5 m long for a mezzanine storage level. Total length = 20 × 5.5 = 110 m. Weight = 110 × 25.4 = 2,794 kg (2.794 tonnes). At ₹58,000 per tonne (May 2026), estimated material cost is approximately ₹1,62,050.
