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 25×25×3
ISA 25×25×3 is used for light fixing cleats, panel stiffeners, cable management brackets, equipment frame secondary members, and door stop angles. It is widely stocked at steel merchants across India.
Worked Example
A panel fabricator in Ahmedabad needs 150 fixing cleats of ISA 25×25×3, each 100 mm long. Total length = 150 × 0.1 = 15 m. Weight = 15 × 1.1 = 16.5 kg. At ₹65,000 per tonne (Ahmedabad, May 2026), material cost is approximately ₹1,073.
