L5×3×5/16 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.

L5×3×5/16 has a 5 in. long leg and a 3 in. short leg, 5/16 in. thick.

At 8.2 lb per foot it is one of the 5 L5×3 sizes, which run from 6.6 to 12.8 lb/ft.

For strong-axis bending its section modulus is Sx = 1.87 in³ and its moment of inertia Ix = 6.24 in⁴, with a plastic modulus Zx = 3.32 in³.
