HSS4×2×1/8 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.

HSS4×2×1/8 is a rectangular tube 4 in. by 2 in. with a 1/8 in. nominal wall.

At 4.75 lb per foot it is the lightest of the 5 HSS4×2 sizes, which run from 4.75 to 12.17 lb/ft.

For strong-axis bending its section modulus is Sx = 1.32 in³ and its moment of inertia Ix = 2.65 in⁴, with a plastic modulus Zx = 1.66 in³.
