L3×2×1/2 angle
Detailing dimensions and section properties from the AISC Shapes Database, 16th Edition. Values are shown to the nearest 1/16 in. as they appear on a shop drawing.
L3×2×1/2 has a 3 in. long leg and a 2 in. short leg, 1/2 in. thick.
At 7.7 lb per foot it is the heaviest of the 5 L3×2 sizes, which run from 3.07 to 7.7 lb/ft.
For strong-axis bending its section modulus is Sx = 1 in³ and its moment of inertia Ix = 1.92 in⁴, with a plastic modulus Zx = 1.78 in³.
