HSS9×7×1/2 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.

HSS9×7×1/2 is a rectangular tube 9 in. by 7 in. with a 1/2 in. nominal wall.

At 48.85 lb per foot it is one of the 6 HSS9×7 sizes, which run from 19.63 to 59.32 lb/ft.

For strong-axis bending its section modulus is Sx = 33 in³ and its moment of inertia Ix = 149 in⁴, with a plastic modulus Zx = 40.5 in³.
