ISHB 225 Weight, Dimensions and IS 808 Properties
ISHB 225 weighs 49.3 kg per metre as per IS 808:1989.
- One 6-metre length weighs 295.8 kg · one 12-metre length weighs 591.6 kg
- Overall depth 225 mm · flange width 225 mm · web thickness 6.5 mm
- Cross-sectional area 6,376 mm² · Ixx = 5,959.0 cm⁴
ISHB 225 is a medium-heavy column section in IS 808:1989. At 49.3 kg/m with equal depth and flange width of 225 mm, it sits between the popular ISHB 200 and ISHB 250 sizes. The equal 225 × 225 mm wide-flange profile gives high biaxial stiffness, suited to medium-height columns in industrial frames where both strong- and weak-axis loads are significant.

Common Applications of ISHB 225
ISHB 225 is used for primary columns in medium industrial structures up to 7 m height, column sections in portal frame buildings with moderate loads, and members in heavy mezzanine floor structures. Its equal 225 × 225 mm cross-section provides near-balanced r_xx and r_yy values — useful for columns loaded in two planes simultaneously. Note that ISHB 225 is less commonly stocked than ISHB 200 and ISHB 250; always verify lead time with your stockist before specifying. SAIL Bhilai supplies ISHB 225 in IS 2062 E250 and E350 grade, typically on indent.
Worked Example
A structural engineer in Pune specifies 14 columns of ISHB 225, each 6 m tall, for a medium industrial storage building. Total length = 14 × 6 = 84 m. Weight = 84 × 49.3 = 4,141.2 kg (4.141 tonnes). At a market rate of ₹63,000 per tonne (Pune, May 2026), the material cost is approximately ₹2,60,900 before base plates, cap plates, and erection.
