HSS10×3×3/8 square/rectangular HSS tube

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.

HSS10×3×3/8 is a rectangular tube 10 in. by 3 in. with a 3/8 in. nominal wall.

At 30.03 lb per foot it is the heaviest of the 5 HSS10×3 sizes, which run from 10.71 to 30.03 lb/ft.

For strong-axis bending its section modulus is Sx = 17.6 in³ and its moment of inertia Ix = 88 in⁴, with a plastic modulus Zx = 23.7 in³.
