ISMB 600 Weight, Dimensions and IS 808 Properties
ISMB 600 weighs 122.6 kg per metre as per IS 808:1989.
- One 6-metre length weighs 735.6 kg · one 12-metre length weighs 1,471.2 kg
- Overall depth 600 mm · flange width 210 mm · web thickness 12.0 mm
- Cross-sectional area 15,620 mm² · Ixx = 91,813.0 cm⁴
ISMB 600 is the largest and heaviest section in the standard ISMB range per IS 808:1989. At 122.6 kg/m with a 210 mm flange, it is used exclusively in heavy industrial structures — major crane bays, long-span bridge girders, and transfer beams carrying very high loads. All handling requires crane equipment.

Common Applications of ISMB 600
ISMB 600 is specified for the heaviest industrial applications — crane runway girders above 50-tonne capacity, major transfer beams in multi-storey frames, and long-span bridge girders. Its Ixx of 91,813 cm⁴ is the highest in the ISMB range. SAIL Bhilai is the primary supplier; ISMB 600 is produced to order in IS 2062 E350 and E410 grades and is not held as regular yard stock.
Worked Example
A heavy engineering plant in Jamshedpur requires 2 crane runway girders of ISMB 600 each 12.0 m long for a 50-tonne EOT crane. Total length = 2 × 12.0 = 24 m. Weight = 24 × 122.6 = 2,942.4 kg (2.942 tonnes). At ₹58,000 per tonne (May 2026), estimated material cost is approximately ₹1,70,660.
