ISA 200×150×15 Weight, Dimensions and IS 808 Properties
ISA 200×150×15 weighs 39.4 kg per metre as per IS 808:1989.
- One 6-metre length weighs 236.4 kg · one 12-metre length weighs 472.8 kg
- Long leg 200 mm · short leg 150 mm · thickness 15 mm · area 50.19 cm²
- Maximum principal moment of inertia Iuu = 2332.0 cm⁴
ISA 200×150×15 is a standard unequal-leg angle in IS 808:1989. At 39.4 kg/m with a 200 mm long leg and 150 mm short leg, it is used for the heaviest standard unequal angle applications — primary truss chord members in very long-span structures, heavily loaded column brackets for overhead crane systems, and major structural connections subject to combined axial and bending loads.

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 200×150×15
ISA 200×150×15 is used for the heaviest standard unequal angle applications — primary truss chord members in very long-span structures, heavily loaded column brackets for overhead crane systems, and major structural connections subject to combined axial and bending loads. 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 Ahmedabad needs 2 primary truss chord members on an 80 m span industrial roof using ISA 200×150×15, each 6000 mm long. Total length = 2 × 6.0 = 12.0 m. Weight = 12.0 × 39.4 = 472.8 kg. At ₹63,000 per tonne (Ahmedabad, May 2026), material cost is approximately ₹29,786 before cutting charges.
