W30×148 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.

W30×148 measures 30 5/8 in. deep with a 10 1/2 in. flange, on a 5/8 in. web and 1 3/16 in. flanges.

At 148 lb per foot it is one of the 16 W30 sizes, which run from 90 to 391 lb/ft.

For strong-axis bending its section modulus is Sx = 436 in³ and its moment of inertia Ix = 6680 in⁴, with a plastic modulus Zx = 500 in³.
