HSS22×20×3/4 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.

HSS22×20×3/4 is a rectangular tube 22 in. by 20 in. with a 3/4 in. nominal wall.

At 201.79 lb per foot it is the heaviest of the 5 HSS22×20 sizes, which run from 87.14 to 201.79 lb/ft.

For strong-axis bending its section modulus is Sx = 367 in³ and its moment of inertia Ix = 4040 in⁴, with a plastic modulus Zx = 432 in³.
