ISA 150×150×15 Weight, Dimensions and IS 808 Properties
ISA 150×150×15 weighs 33.5 kg per metre as per IS 808:1989.
- One 6-metre length weighs 201.0 kg · one 12-metre length weighs 402.0 kg
- Leg 150 mm × thickness 15 mm · root radius 16.0 mm
- Cross-sectional area 42.68 cm² · Iuu = 803.0 cm⁴
ISA 150×150×15 is the heaviest standard 150 mm equal-leg angle in IS 808:1989. At 33.5 kg/m it is used for the most heavily loaded primary structural members in large heavy industrial trusses and compound column sections where the thinner variants are under-capacity.

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 150×150×15
ISA 150×150×15 is used for the most heavily loaded primary chord members in large-span heavy trusses, compound column sections under maximum axial load in multi-storey industrial frames, primary heavy bracing under extreme lateral loads, and large bolted connection nodes. Available from JSPL and Tata Steel.
Worked Example
A structural engineer in Ahmedabad specifies ISA 150×150×15 for 6 primary chord members, each 6 m long, for a 42 m span heavy crane girder truss. Total length = 6 × 6 = 36 m. Weight = 36 × 33.5 = 1,206 kg (1.206 tonnes). At ₹62,000 per tonne (Ahmedabad, May 2026), material cost is approximately ₹74,772.
