ST10×48 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.

ST10×48 measures 10 1/8 in. deep with a 7 1/4 in. flange, on a 13/16 in. web and 15/16 in. flanges.

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

For strong-axis bending its section modulus is Sx = 20.3 in³ and its moment of inertia Ix = 143 in⁴, with a plastic modulus Zx = 36.9 in³.
