Indian Standard Unequal Angle — IS 808:2021 | Depth 30mm × Width 20mm
ISA 30x20x3 weighs 1.1 kg per metre as per IS 808. For a standard 6m length, the total weight would be 6.6 kg.
ISA 30x20x3 has leg dimensions of 30mm × 20mm with a thickness of 3mm.
The moment of inertia of ISA 30x20x3 is Ixx = 0.8 cm⁴ (major axis) and Iyy = 0.26 cm⁴ (minor axis).
ISA 30x20x3 (Unequal Angle) is typically used for truss members with unequal loading and connections. It provides a section modulus of Zxx = 0.37 cm³, suitable for beams with moderate bending requirements.
A 6m length of ISA 30x20x3 weighs 6.6 kg (0.007 tonnes). Weight formula: 1.1 kg/m × 6m = 6.6 kg.
