W8×58 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.
W8×58 measures 8 3/4 in. deep with a 8 1/4 in. flange, on a 1/2 in. web and 13/16 in. flanges.
At 58 lb per foot it is one of the 13 W8 sizes, which run from 10 to 67 lb/ft.
For strong-axis bending its section modulus is Sx = 52 in³ and its moment of inertia Ix = 228 in⁴, with a plastic modulus Zx = 59.8 in³.
