HSS4×3×3/16 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.

HSS4×3×3/16 is a rectangular tube 4 in. by 3 in. with a 3/16 in. nominal wall.

At 8.15 lb per foot it is one of the 5 HSS4×3 sizes, which run from 5.61 to 14.72 lb/ft.

For strong-axis bending its section modulus is Sx = 2.47 in³ and its moment of inertia Ix = 4.93 in⁴, with a plastic modulus Zx = 3 in³.
