L3×3×3/16 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.
L3×3×3/16 has equal 3 in. legs, 3/16 in. thick.
At 3.71 lb per foot it is the lightest of the 6 L3×3 sizes, which run from 3.71 to 9.4 lb/ft.
For strong-axis bending its section modulus is Sx = 0.433 in³ and its moment of inertia Ix = 0.948 in⁴, with a plastic modulus Zx = 0.774 in³.
