W10×30 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.

W10×30 measures 10 1/2 in. deep with a 5 3/4 in. flange, on a 5/16 in. web and 1/2 in. flanges.

At 30 lb per foot it is one of the 18 W10 sizes, which run from 12 to 112 lb/ft.

For strong-axis bending its section modulus is Sx = 32.4 in³ and its moment of inertia Ix = 170 in⁴, with a plastic modulus Zx = 36.6 in³.
