W16×50 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.
W16×50 measures 16 1/4 in. deep with a 7 1/8 in. flange, on a 3/8 in. web and 5/8 in. flanges.
At 50 lb per foot it is one of the 11 W16 sizes, which run from 26 to 100 lb/ft.
For strong-axis bending its section modulus is Sx = 81 in³ and its moment of inertia Ix = 659 in⁴, with a plastic modulus Zx = 92 in³.
