HSS8×4×3/16 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.

HSS8×4×3/16 is a rectangular tube 8 in. by 4 in. with a 3/16 in. nominal wall.

At 14.53 lb per foot it is one of the 7 HSS8×4 sizes, which run from 9.86 to 42.3 lb/ft.

For strong-axis bending its section modulus is Sx = 8.27 in³ and its moment of inertia Ix = 33.1 in⁴, with a plastic modulus Zx = 10.2 in³.
