HSS5×5×1/8 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.

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

At 8.16 lb per foot it is the lightest of the 6 HSS5×5 sizes, which run from 8.16 to 28.43 lb/ft.

For strong-axis bending its section modulus is Sx = 3.52 in³ and its moment of inertia Ix = 8.8 in⁴, with a plastic modulus Zx = 4.07 in³.
