ISA 25×25×5 Weight, Dimensions and IS 808 Properties
ISA 25×25×5 weighs 1.8 kg per metre as per IS 808:1989.
- One 6-metre length weighs 10.8 kg · one 12-metre length weighs 21.6 kg
- Leg 25 mm × thickness 5 mm · root radius 3.5 mm
- Cross-sectional area 2.26 cm² · Iuu = 1.1 cm⁴
ISA 25×25×5 is the heavier variant of the 25 mm equal-leg angle in IS 808:1989. At 1.8 kg/m it offers greater resistance than ISA 25×25×3 for the same leg size, making it suitable for stressed cleats and fixing brackets in light structural applications.

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 25×25×5
ISA 25×25×5 is used for stressed fixing cleats, gusset plate edge stiffeners, equipment base frame connections, and light secondary bracing where the 3 mm variant is under-strength. Commonly stocked at general steel merchants across India.
Worked Example
A machine fabricator in Pune needs 80 equipment mounting cleats of ISA 25×25×5, each 120 mm long. Total length = 80 × 0.12 = 9.6 m. Weight = 9.6 × 1.8 = 17.3 kg. At ₹65,000 per tonne (Pune, May 2026), material cost is approximately ₹1,123.
