HSS12×4×3/16 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.

HSS12×4×3/16 is a rectangular tube 12 in. by 4 in. with a 3/16 in. nominal wall.

At 19.63 lb per foot it is the lightest of the 6 HSS12×4 sizes, which run from 19.63 to 59.32 lb/ft.

For strong-axis bending its section modulus is Sx = 15.3 in³ and its moment of inertia Ix = 91.8 in⁴, with a plastic modulus Zx = 19.6 in³.
