L3×3×7/16 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.

L3×3×7/16 has equal 3 in. legs, 7/16 in. thick.

At 8.3 lb per foot it is one 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 = 0.946 in³ and its moment of inertia Ix = 1.98 in⁴, with a plastic modulus Zx = 1.7 in³.
