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 200×200×25
ISA 200×200×25 is used for the most heavily loaded compound column sections in large infrastructure and heavy industrial frames, critical connection gusset and splice plates, large built-up girder chord members in very heavy process plant structures, and primary members in extreme-load applications. Available from JSPL and Tata Steel to special order.
Worked Example
A structural engineer in Mumbai specifies ISA 200×200×25 for 4 primary chord members, each 6 m long, for a very heavy 55 m span process plant truss requiring maximum section capacity. Total length = 4 × 6 = 24 m. Weight = 24 × 73.6 = 1,766.4 kg (1.766 tonnes). At ₹62,000 per tonne (Mumbai, May 2026), material cost is approximately ₹109,517.
