HSS4×4×1/2 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.

HSS4×4×1/2 is a square tube 4 in. by 4 in. with a 1/2 in. nominal wall.

At 21.63 lb per foot it is the heaviest of the 6 HSS4×4 sizes, which run from 6.46 to 21.63 lb/ft.

For strong-axis bending its section modulus is Sx = 5.97 in³ and its moment of inertia Ix = 11.9 in⁴, with a plastic modulus Zx = 7.7 in³.
