HSS20×16×1/4 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.

HSS20×16×1/4 is a rectangular tube 20 in. by 16 in. with a 1/4 in. nominal wall.

At 59.85 lb per foot it is the lightest of the 6 HSS20×16 sizes, which run from 59.85 to 171.16 lb/ft.

For strong-axis bending its section modulus is Sx = 100 in³ and its moment of inertia Ix = 1000 in⁴, with a plastic modulus Zx = 117 in³.
