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 60×40×5
ISA 60×40×5 is used for purlin and girt cleats in light-to-medium shed structures, secondary beam seating connections, and diagonal bracing in light frames. 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 Surat needs 80 purlin cleats for a 30 m × 15 m shed using ISA 60×40×5, each 150 mm long. Total length = 80 × 0.15 = 12.0 m. Weight = 12.0 × 3.8 = 45.6 kg. At ₹63,000 per tonne (Surat, May 2026), material cost is approximately ₹2,872 before cutting charges.
