HSS7×5×1/8 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.

HSS7×5×1/8 is a rectangular tube 7 in. by 5 in. with a 1/8 in. nominal wall.

At 9.86 lb per foot it is the lightest of the 6 HSS7×5 sizes, which run from 9.86 to 35.24 lb/ft.

For strong-axis bending its section modulus is Sx = 5.52 in³ and its moment of inertia Ix = 19.3 in⁴, with a plastic modulus Zx = 6.53 in³.
