W10×12 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.

W10×12 measures 9 7/8 in. deep with a 4 in. flange, on a 3/16 in. web and 3/16 in. flanges.

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

For strong-axis bending its section modulus is Sx = 10.9 in³ and its moment of inertia Ix = 53.8 in⁴, with a plastic modulus Zx = 12.6 in³.
