W6×25 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.
W6×25 measures 6 3/8 in. deep with a 6 1/8 in. flange, on a 5/16 in. web and 7/16 in. flanges.
At 25 lb per foot it is the heaviest of the 7 W6 sizes, which run from 8.5 to 25 lb/ft.
For strong-axis bending its section modulus is Sx = 16.7 in³ and its moment of inertia Ix = 53.4 in⁴, with a plastic modulus Zx = 18.9 in³.
