ST10×43 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.

ST10×43 measures 10 1/8 in. deep with a 7 in. flange, on a 11/16 in. web and 15/16 in. flanges.

At 43 lb per foot it is one of the 4 ST10 sizes, which run from 33 to 48 lb/ft.

For strong-axis bending its section modulus is Sx = 17.2 in³ and its moment of inertia Ix = 124 in⁴, with a plastic modulus Zx = 31.1 in³.
