C10×20 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.

C10×20 measures 10 in. deep with a 2 3/4 in. flange and a 3/8 in. web.

At 20 lb per foot it is one of the 4 C10 sizes, which run from 15.3 to 30 lb/ft.

For strong-axis bending its section modulus is Sx = 15.8 in³ and its moment of inertia Ix = 78.9 in⁴, with a plastic modulus Zx = 19.4 in³.
