ISHB 400 Weight, Dimensions and IS 808 Properties
ISHB 400 weighs 92.5 kg per metre as per IS 808:1989.
- One 6-metre length weighs 555.0 kg · one 12-metre length weighs 1,110.0 kg
- Overall depth 400 mm · flange width 250 mm · web thickness 8.6 mm
- Cross-sectional area 11,776 mm² · Ixx = 28,083.2 cm⁴
ISHB 400 is a very heavy column section in IS 808:1989. At 92.5 kg/m with a 400 mm depth and 250 mm flange, it is used for heavily loaded primary columns in tall industrial structures and crane runway frames. At this weight, crane handling is required during fabrication, transport, and erection — standard manual handling is not practical beyond short lengths.

Common Applications of ISHB 400
ISHB 400 is used as primary columns in tall heavy industrial buildings above 10 m height, column sections in heavy-duty EOT crane structures, stanchions in high-bay warehouses, and column members in multi-storey industrial steel frames with significant floor loads. The r_xx/r_yy ratio of approximately 3.07 makes this section substantially stiffer about the x–x axis — y–y axis buckling becomes the governing design condition without adequate intermediate restraint. SAIL Bhilai produces ISHB 400 in IS 2062 E250, E350, and E410 grades on indent.
Worked Example
A structural engineer in Nagpur specifies 10 columns of ISHB 400, each 10 m tall, for a high-bay heavy workshop. Total length = 10 × 10 = 100 m. Weight = 100 × 92.5 = 9,250 kg (9.25 tonnes). At a market rate of ₹64,000 per tonne (Nagpur, May 2026), the material cost is approximately ₹5,92,000 before base plates, cap plates, and erection.
