HSS24×20×5/16 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.

HSS24×20×5/16 is a rectangular tube 24 in. by 20 in. with a 5/16 in. nominal wall.

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

For strong-axis bending its section modulus is Sx = 186 in³ and its moment of inertia Ix = 2230 in⁴, with a plastic modulus Zx = 215 in³.
