MC6×7 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.

MC6×7 measures 6 in. deep with a 1 7/8 in. flange and a 3/16 in. web.

At 7 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 = 3.81 in³ and its moment of inertia Ix = 11.4 in⁴, with a plastic modulus Zx = 4.5 in³.
