Practical Notes
This code provides geometric properties only. Always specify the required aluminium alloy grade (e.g., from IS 733) to ensure adequate mechanical strength.
Pay special attention to the orientation of the unequal legs during detailing to maximize the moment of inertia against the primary bending axis.
Tolerances for these sections are typically governed by IS 3965 rather than this geometric standard.
