ST10×33 tee (cut from a standard 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.

ST10×33 measures 10 in. deep with a 6 1/4 in. flange, on a 1/2 in. web and 13/16 in. flanges.

At 33 lb per foot it is the lightest of the 4 ST10 sizes, which run from 33 to 48 lb/ft.

For strong-axis bending its section modulus is Sx = 12.9 in³ and its moment of inertia Ix = 92.9 in⁴, with a plastic modulus Zx = 23.4 in³.
