MC6×12 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.

MC6×12 measures 6 in. deep with a 2 1/2 in. flange and a 5/16 in. web.

At 12 lb per foot it is one of the 7 MC6 sizes, which run from 6.5 to 18 lb/ft.

For strong-axis bending its section modulus is Sx = 6.24 in³ and its moment of inertia Ix = 18.7 in⁴, with a plastic modulus Zx = 7.47 in³.
