Indian Standard Equal Angle — IS 808:2021 | Depth 20mm × Width 20mm
ISA 20x20x3 weighs 0.8 kg per metre as per IS 808. For a standard 6m length, the total weight would be 4.8 kg.
ISA 20x20x3 has leg dimensions of 20mm × 20mm with a thickness of 3mm.
The moment of inertia of ISA 20x20x3 is Ixx = 0.28 cm⁴ (major axis) and Iyy = 0.28 cm⁴ (minor axis).
ISA 20x20x3 (Equal Angle) is typically used for truss members, bracings, and connections in steel structures. It provides a section modulus of Zxx = 0.21 cm³, suitable for beams with moderate bending requirements.
A 6m length of ISA 20x20x3 weighs 4.8 kg (0.005 tonnes). Weight formula: 0.8 kg/m × 6m = 4.8 kg.
