ISA 150×100×10 Weight, Dimensions and IS 808 Properties
ISA 150×100×10 weighs 18.8 kg per metre as per IS 808:1989.
- One 6-metre length weighs 112.8 kg · one 12-metre length weighs 225.6 kg
- Long leg 150 mm · short leg 100 mm · thickness 10 mm · area 24.0 cm²
- Maximum principal moment of inertia Iuu = 635.3 cm⁴
ISA 150×100×10 is a standard unequal-leg angle in IS 808:1989. At 18.8 kg/m with a 150 mm long leg and 100 mm short leg, it is used for heavy structural bracing in multi-storey industrial frames, column-base gusset connections, heavy truss chord splice angles, and staircase main stringers in heavy industrial buildings.

Common Applications of ISA 150×100×10
ISA 150×100×10 is used for heavy structural bracing in multi-storey industrial frames, column-base gusset connections, heavy truss chord splice angles, and staircase main stringers in heavy industrial buildings. 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 Chennai needs 6 column-base bracing angles on a multi-storey industrial frame using ISA 150×100×10, each 2500 mm long. Total length = 6 × 2.5 = 15.0 m. Weight = 15.0 × 18.8 = 282.0 kg. At ₹63,000 per tonne (Chennai, May 2026), material cost is approximately ₹17,766 before cutting charges.
