HSS7×3×1/4 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.

HSS7×3×1/4 is a rectangular tube 7 in. by 3 in. with a 1/4 in. nominal wall.

At 15.62 lb per foot it is one of the 6 HSS7×3 sizes, which run from 8.16 to 28.43 lb/ft.

For strong-axis bending its section modulus is Sx = 7.19 in³ and its moment of inertia Ix = 25.2 in⁴, with a plastic modulus Zx = 9.22 in³.
