ISA 75×75×10 Weight, Dimensions and IS 808 Properties
ISA 75×75×10 weighs 10.9 kg per metre as per IS 808:1989.
- One 6-metre length weighs 65.4 kg · one 12-metre length weighs 130.8 kg
- Leg 75 mm × thickness 10 mm · root radius 9.0 mm
- Cross-sectional area 13.94 cm² · Iuu = 64.5 cm⁴
ISA 75×75×10 is the heaviest standard variant of the 75 mm equal-leg angle in IS 808:1989. At 10.9 kg/m it is used for heavily loaded truss chord members, built-up section compound struts under significant axial compression, and primary structural members in medium industrial buildings.

Dimensions and properties as per IS 808:1989 (Reaffirmed 2001). Mass tolerance: ±3% per piece as per IS 808. u–u is the major principal axis at 45° to both legs; v–v is the minor principal axis. Zvv is not published in IS 808:1989 for angle sections.
Common Applications of ISA 75×75×10
ISA 75×75×10 is used for heavily loaded back-to-back compound chord members in medium-span trusses, primary bracing members under high axial load, column lacings in compound column sections, and connections requiring maximum bearing area. Available from JSPL and Tata Steel.
Worked Example
A structural engineer in Delhi specifies ISA 75×75×10 for 12 truss chord members, each 6 m long, in a heavily loaded 18 m span truss. Total length = 12 × 6 = 72 m. Weight = 72 × 10.9 = 784.8 kg (0.785 tonnes). At ₹62,000 per tonne (Delhi, May 2026), material cost is approximately ₹48,658.
