MC13×35 MC 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.

MC13×35 measures 13 in. deep with a 4 1/8 in. flange and a 7/16 in. web.

At 35 lb per foot it is one of the 4 MC13 sizes, which run from 31.8 to 50 lb/ft.

For strong-axis bending its section modulus is Sx = 38.8 in³ and its moment of inertia Ix = 252 in⁴, with a plastic modulus Zx = 46.5 in³.
