HSS6×3×3/16 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.

HSS6×3×3/16 is a rectangular tube 6 in. by 3 in. with a 3/16 in. nominal wall.

At 10.7 lb per foot it is one of the 6 HSS6×3 sizes, which run from 7.31 to 25.03 lb/ft.

For strong-axis bending its section modulus is Sx = 4.47 in³ and its moment of inertia Ix = 13.4 in⁴, with a plastic modulus Zx = 5.59 in³.
