ISHB 250 Weight, Dimensions and IS 808 Properties
ISHB 250 weighs 54.7 kg per metre as per IS 808:1989.
- One 6-metre length weighs 328.2 kg · one 12-metre length weighs 656.4 kg
- Overall depth 250 mm · flange width 250 mm · web thickness 6.9 mm
- Cross-sectional area 6,971 mm² · Ixx = 7,983.9 cm⁴
ISHB 250 is the largest equal-flange ISHB section in IS 808:1989. At 54.7 kg/m with equal depth and flange width of 250 mm, it is widely used as a primary column in medium industrial structures. Above ISHB 250, the flange width remains fixed at 250 mm while the depth increases — so ISHB 250 represents a transition point in the ISHB range where the section geometry shifts from square to rectangular.

Common Applications of ISHB 250
ISHB 250 is used as primary columns in medium industrial buildings up to 8 m height, multi-storey light steel frames, heavy mezzanine structures, and as column sections in portal frame buildings carrying significant axial load. Its 250 × 250 mm equal profile gives a well-balanced r_xx/r_yy ratio of approximately 2.0 — good biaxial column performance. SAIL Bhilai produces ISHB 250 in IS 2062 E250 and E350 grade as standard stock; also available from major structural steel stockists across India.
Worked Example
A structural engineer in Mumbai specifies 24 columns of ISHB 250, each 6 m tall, for a multi-bay medium industrial building. Total length = 24 × 6 = 144 m. Weight = 144 × 54.7 = 7,876.8 kg (7.877 tonnes). At a market rate of ₹63,500 per tonne (Mumbai, May 2026), the material cost is approximately ₹5,00,180 before base plates and connections.
