HSS5×2×1/8 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.

HSS5×2×1/8 is a rectangular tube 5 in. by 2 in. with a 1/8 in. nominal wall.

At 5.61 lb per foot it is the lightest of the 5 HSS5×2 sizes, which run from 5.61 to 14.72 lb/ft.

For strong-axis bending its section modulus is Sx = 1.86 in³ and its moment of inertia Ix = 4.65 in⁴, with a plastic modulus Zx = 2.37 in³.
