W12×22 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.
W12×22 measures 12 1/4 in. deep with a 4 in. flange, on a 1/4 in. web and 7/16 in. flanges.
At 22 lb per foot it is one of the 29 W12 sizes, which run from 14 to 336 lb/ft.
For strong-axis bending its section modulus is Sx = 25.4 in³ and its moment of inertia Ix = 156 in⁴, with a plastic modulus Zx = 29.3 in³.
