HP10×42 H-pile

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.

HP10×42 measures 9 3/4 in. deep with a 10 1/8 in. flange, on a 7/16 in. web and 7/16 in. flanges.

At 42 lb per foot it is the lightest of the 2 HP10 sizes, which run from 42 to 57 lb/ft.

For strong-axis bending its section modulus is Sx = 43.4 in³ and its moment of inertia Ix = 210 in⁴, with a plastic modulus Zx = 48.3 in³.
