HSS2×1×1/8 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.

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

At 2.2 lb per foot it is the lightest of the 2 HSS2×1 sizes, which run from 2.2 to 3.04 lb/ft.

For strong-axis bending its section modulus is Sx = 0.28 in³ and its moment of inertia Ix = 0.28 in⁴, with a plastic modulus Zx = 0.366 in³.
