W18×119 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.
W18×119 measures 19 in. deep with a 11 1/4 in. flange, on a 5/8 in. web and 1 1/16 in. flanges.
At 119 lb per foot it is one of the 23 W18 sizes, which run from 35 to 311 lb/ft.
For strong-axis bending its section modulus is Sx = 231 in³ and its moment of inertia Ix = 2190 in⁴, with a plastic modulus Zx = 262 in³.
