WT3×6 tee (cut from a wide-flange)
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.
WT3×6 measures 3 in. deep with a 4 in. flange, on a 1/4 in. web and 1/4 in. flanges.
At 6 lb per foot it is one of the 7 WT3 sizes, which run from 4.25 to 12.5 lb/ft.
For strong-axis bending its section modulus is Sx = 0.564 in³ and its moment of inertia Ix = 1.32 in⁴, with a plastic modulus Zx = 1.01 in³.
