HSS6×4×3/8 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.

HSS6×4×3/8 is a rectangular tube 6 in. by 4 in. with a 3/8 in. nominal wall.

At 22.37 lb per foot it is one of the 6 HSS6×4 sizes, which run from 8.16 to 28.43 lb/ft.

For strong-axis bending its section modulus is Sx = 9.43 in³ and its moment of inertia Ix = 28.3 in⁴, with a plastic modulus Zx = 11.9 in³.
