HSS12×3×1/4 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.

HSS12×3×1/4 is a rectangular tube 12 in. by 3 in. with a 1/4 in. nominal wall.

At 24.12 lb per foot it is one of the 3 HSS12×3 sizes, which run from 18.35 to 29.72 lb/ft.

For strong-axis bending its section modulus is Sx = 17.2 in³ and its moment of inertia Ix = 103 in⁴, with a plastic modulus Zx = 22.9 in³.
