HSS18×10×1/4 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.

HSS18×10×1/4 is a rectangular tube 18 in. by 10 in. with a 1/4 in. nominal wall.

At 46.24 lb per foot it is the lightest of the 5 HSS18×10 sizes, which run from 46.24 to 110.36 lb/ft.

For strong-axis bending its section modulus is Sx = 62.9 in³ and its moment of inertia Ix = 566 in⁴, with a plastic modulus Zx = 76 in³.
