HSS3×3×1/4 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.

HSS3×3×1/4 is a square tube 3 in. by 3 in. with a 1/4 in. nominal wall.

At 8.81 lb per foot it is one of the 5 HSS3×3 sizes, which run from 4.75 to 12.17 lb/ft.

For strong-axis bending its section modulus is Sx = 2.01 in³ and its moment of inertia Ix = 3.02 in⁴, with a plastic modulus Zx = 2.48 in³.
