HSS12×8×3/16 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.

HSS12×8×3/16 is a rectangular tube 12 in. by 8 in. with a 3/16 in. nominal wall.

At 24.73 lb per foot it is the lightest of the 6 HSS12×8 sizes, which run from 24.73 to 76.33 lb/ft.

For strong-axis bending its section modulus is Sx = 23.4 in³ and its moment of inertia Ix = 140 in⁴, with a plastic modulus Zx = 27.8 in³.
