HSS3×1×3/16 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.

HSS3×1×3/16 is a rectangular tube 3 in. by 1 in. with a 3/16 in. nominal wall.

At 4.32 lb per foot it is the heaviest of the 2 HSS3×1 sizes, which run from 3.05 to 4.32 lb/ft.

For strong-axis bending its section modulus is Sx = 0.713 in³ and its moment of inertia Ix = 1.07 in⁴, with a plastic modulus Zx = 0.989 in³.
