HSS7×7×1/2 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.

HSS7×7×1/2 is a square tube 7 in. by 7 in. with a 1/2 in. nominal wall.

At 42.05 lb per foot it is one of the 7 HSS7×7 sizes, which run from 11.56 to 50.81 lb/ft.

For strong-axis bending its section modulus is Sx = 23 in³ and its moment of inertia Ix = 80.5 in⁴, with a plastic modulus Zx = 27.9 in³.
