W6×15 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.

W6×15 measures 6 in. deep with a 6 in. flange, on a 1/4 in. web and 1/4 in. flanges.

At 15 lb per foot it is one of the 7 W6 sizes, which run from 8.5 to 25 lb/ft.

For strong-axis bending its section modulus is Sx = 9.72 in³ and its moment of inertia Ix = 29.1 in⁴, with a plastic modulus Zx = 10.8 in³.
