ISA 80×60×6 Weight, Dimensions and IS 808 Properties
ISA 80×60×6 weighs 6.5 kg per metre as per IS 808:1989.
- One 6-metre length weighs 39.0 kg · one 12-metre length weighs 78.0 kg
- Long leg 80 mm · short leg 60 mm · thickness 6 mm · area 8.22 cm²
- Maximum principal moment of inertia Iuu = 63.44 cm⁴
ISA 80×60×6 is a standard unequal-leg angle in IS 808:1989. At 6.5 kg/m with a 80 mm long leg and 60 mm short leg, it is used for medium structural bracing, beam-to-column connection angles, staircase stringers, and secondary framing connections where the wider 60 mm short leg improves bolt-gauge flexibility.

Dimensions and properties as per IS 808:1989 (reaffirmed 2021). x–x axis is parallel to the long leg; y–y axis is parallel to the short leg; u–u is the maximum principal axis at angle α to x–x. Mass tolerance: ±3% per piece per IS 808.
Common Applications of ISA 80×60×6
ISA 80×60×6 is used for medium structural bracing, beam-to-column connection angles, staircase stringers, and secondary framing connections where the wider 60 mm short leg improves bolt-gauge flexibility. General steel merchants and angle stockists carry this size in IS 2062 E250 grade in 6 m and 12 m lengths. JSPL, SAIL, and RINL (Vizag Steel) all roll this designation to IS 808:1989 as standard stock.
Worked Example
A fabricator in Hyderabad needs 24 beam-to-column connection angles on a mezzanine frame using ISA 80×60×6, each 300 mm long. Total length = 24 × 0.3 = 7.2 m. Weight = 7.2 × 6.5 = 46.8 kg. At ₹63,000 per tonne (Hyderabad, May 2026), material cost is approximately ₹2,948 before cutting charges.
