HSS5×3×3/8 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.

HSS5×3×3/8 is a rectangular tube 5 in. by 3 in. with a 3/8 in. nominal wall.

At 17.27 lb per foot it is one of the 6 HSS5×3 sizes, which run from 6.46 to 21.63 lb/ft.

For strong-axis bending its section modulus is Sx = 5.65 in³ and its moment of inertia Ix = 14.1 in⁴, with a plastic modulus Zx = 7.34 in³.
