2L6×6×5/16 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.

2L6×6×5/16 has equal 6 in. legs, 5/16 in. thick, in contact back to back.

At 24.8 lb per foot it is the lightest of the 27 2L6×6 sizes, which run from 24.8 to 74.8 lb/ft.

For strong-axis bending its section modulus is Sx = 5.9 in³ and its moment of inertia Ix = 26 in⁴, with a plastic modulus Zx = 10.5 in³.
