HSS24×20×3/8 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.

HSS24×20×3/8 is a rectangular tube 24 in. by 20 in. with a 3/8 in. nominal wall.

At 109.15 lb per foot it is one of the 5 HSS24×20 sizes, which run from 91.39 to 212 lb/ft.

For strong-axis bending its section modulus is Sx = 220 in³ and its moment of inertia Ix = 2640 in⁴, with a plastic modulus Zx = 256 in³.
