W10×39 wide-flange 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.

W10×39 measures 9 7/8 in. deep with a 8 in. flange, on a 5/16 in. web and 1/2 in. flanges.

At 39 lb per foot it is one of the 18 W10 sizes, which run from 12 to 112 lb/ft.

For strong-axis bending its section modulus is Sx = 42.1 in³ and its moment of inertia Ix = 209 in⁴, with a plastic modulus Zx = 46.8 in³.
