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 65×65×6
ISA 65×65×6 is used for truss bottom chord members in 10–14 m span structures, back-to-back compound struts in braced bays, diagonal bracing members, secondary beam support brackets, and gusset plate connections. Widely stocked in IS 2062 E250 grade by JSPL, Tata Steel, and general merchants across India.
Worked Example
A structural fabricator in Vadodara needs 8 truss bottom chord members of ISA 65×65×6, each 6 m long, for a 12 m span roof truss. Total length = 8 × 6 = 48 m. Weight = 48 × 5.9 = 283.2 kg. At ₹62,000 per tonne (Vadodara, May 2026), material cost is approximately ₹17,558.
