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 150×150×10
ISA 150×150×10 is used for primary chord members in 30–40 m span heavy industrial trusses, back-to-back compound column sections in steel-framed multi-storey industrial buildings, primary heavy wind bracing, and large bolted connection joints. Stocked by JSPL and Tata Steel in IS 2062 E250 grade.
Worked Example
A structural engineer in Mumbai specifies ISA 150×150×10 for 10 primary chord members, each 6 m long, for a 36 m span crane gantry truss. Total length = 10 × 6 = 60 m. Weight = 60 × 22.8 = 1,368 kg (1.368 tonnes). At ₹62,000 per tonne (Mumbai, May 2026), material cost is approximately ₹84,816.
