MT6×5 tee (cut from a junior beam)

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.

MT6×5 measures 5 7/8 in. deep with a 3 1/4 in. flange, on a 1/8 in. web and 3/16 in. flanges.

At 5 lb per foot it is the lightest of the 3 MT6 sizes, which run from 5 to 5.9 lb/ft.

For strong-axis bending its section modulus is Sx = 1.36 in³ and its moment of inertia Ix = 5.62 in⁴, with a plastic modulus Zx = 2.45 in³.
