C6×13 channel

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.

C6×13 measures 6 in. deep with a 2 1/8 in. flange and a 7/16 in. web.

At 13 lb per foot it is the heaviest of the 3 C6 sizes, which run from 8.2 to 13 lb/ft.

For strong-axis bending its section modulus is Sx = 5.78 in³ and its moment of inertia Ix = 17.3 in⁴, with a plastic modulus Zx = 7.29 in³.
