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 200×200×15
ISA 200×200×15 is used for primary chord members in 45–55 m span very heavy industrial trusses, built-up compound column sections in large infrastructure and industrial frames, heavy crane gantry girder chord members, primary heavy wind bracing under extreme lateral loads, and major structural connection nodes. Available from JSPL and Tata Steel.
Worked Example
A structural engineer in Mumbai specifies ISA 200×200×15 for 6 primary chord members, each 6 m long, for a 50 m span heavy crane truss in a steel works. Total length = 6 × 6 = 36 m. Weight = 36 × 45.3 = 1,630.8 kg (1.631 tonnes). At ₹62,000 per tonne (Mumbai, May 2026), material cost is approximately ₹101,110.
