HSS2×2×1/8 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.

HSS2×2×1/8 is a square tube 2 in. by 2 in. with a 1/8 in. nominal wall.

At 3.05 lb per foot it is the lightest of the 3 HSS2×2 sizes, which run from 3.05 to 5.41 lb/ft.

For strong-axis bending its section modulus is Sx = 0.486 in³ and its moment of inertia Ix = 0.486 in⁴, with a plastic modulus Zx = 0.584 in³.
