Indian Standard Unequal Angle — IS 808:2021 | Depth 45mm × Width 30mm
ISA 45x30x4 weighs 2.2 kg per metre as per IS 808. For a standard 6m length, the total weight would be 13.2 kg.
ISA 45x30x4 has leg dimensions of 45mm × 30mm with a thickness of 4mm.
The moment of inertia of ISA 45x30x4 is Ixx = 3.9 cm⁴ (major axis) and Iyy = 1.3 cm⁴ (minor axis).
ISA 45x30x4 (Unequal Angle) is typically used for truss members with unequal loading and connections. It provides a section modulus of Zxx = 1.2 cm³, suitable for beams with moderate bending requirements.
A 6m length of ISA 45x30x4 weighs 13.2 kg (0.013 tonnes). Weight formula: 2.2 kg/m × 6m = 13.2 kg.
