HSS16×4×5/16 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.

HSS16×4×5/16 is a rectangular tube 16 in. by 4 in. with a 5/16 in. nominal wall.

At 40.35 lb per foot it is one of the 6 HSS16×4 sizes, which run from 24.73 to 76.33 lb/ft.

For strong-axis bending its section modulus is Sx = 38.5 in³ and its moment of inertia Ix = 308 in⁴, with a plastic modulus Zx = 51.1 in³.
