HSS9×3×1/4 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.

HSS9×3×1/4 is a rectangular tube 9 in. by 3 in. with a 1/4 in. nominal wall.

At 19.02 lb per foot it is one of the 5 HSS9×3 sizes, which run from 14.53 to 35.24 lb/ft.

For strong-axis bending its section modulus is Sx = 10.7 in³ and its moment of inertia Ix = 48.2 in⁴, with a plastic modulus Zx = 14 in³.
