HSS7×2×1/8 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.

HSS7×2×1/8 is a rectangular tube 7 in. by 2 in. with a 1/8 in. nominal wall.

At 7.31 lb per foot it is the lightest of the 3 HSS7×2 sizes, which run from 7.31 to 13.91 lb/ft.

For strong-axis bending its section modulus is Sx = 3.16 in³ and its moment of inertia Ix = 11.1 in⁴, with a plastic modulus Zx = 4.13 in³.
