2L5×5×5/16×3/8 double 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.

2L5×5×5/16×3/8 has equal 5 in. legs, 5/16 in. thick, spaced 3/8 in. back to back.

At 20.6 lb per foot it is one of the 21 2L5×5 sizes, which run from 20.6 to 54.4 lb/ft.

For strong-axis bending its section modulus is Sx = 4.08 in³ and its moment of inertia Ix = 14.9 in⁴, with a plastic modulus Zx = 7.3 in³.
