HSS8×4×1/4 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.

HSS8×4×1/4 is a rectangular tube 8 in. by 4 in. with a 1/4 in. nominal wall.

At 19.02 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 = 10.6 in³ and its moment of inertia Ix = 42.5 in⁴, with a plastic modulus Zx = 13.3 in³.
