HSS10x10x1/4 — Dimensions, Weight & Section Properties
Hollow structural section per ASTM A500 / AISC Steel Construction Manual
HSS10x10x1/4 is an American hollow structural section (HSS) 10×10 inches (254×254 mm) with a nominal 0.25 in wall, weighing 32.63 pounds per foot (48.6 kg/m). Section properties below are the AISC published values, computed with the A500 design wall thickness of 0.93×nominal — with metric equivalents alongside.
Typical uses: columns, braces, truss members, equipment frames, and architectural steel — closed sections excel in compression and torsion and take paint beautifully. For a quick stiffness check, see the deflection example below or open the beam calculator with your own span and load.

Deflection example
A simply supported HSS10x10x1/4 spanning 16 ft with a 10 kip point load at midspan deflects 0.36 in (E = 29,000 ksi, Ix = 141 in⁴). The L/360 serviceability limit for this span is 0.53 in — the shape passes this quick check.

Frequently asked questions
How much does a HSS10x10x1/4 tube weigh?
HSS10x10x1/4 weighs 32.63 pounds per foot (48.6 kg/m). A 20 ft bar weighs 653 lb and a 40 ft bar 1,305 lb.
What are the dimensions of a HSS10x10x1/4?
HSS10x10x1/4 is 10×10 in (254×254 mm) outside, with a nominal wall of 0.25 in. Note that A500 tolerances put the design wall at 0.93×nominal (0.233 in) — the section properties listed already account for this.
What are the dimensions of a HSS10x10x1/4 in mm?
HSS10x10x1/4 is 254×254 mm outside with a nominal wall of 6.4 mm. In metric section properties: Ix = 5,869 cm⁴, Sx = 464 cm³.
How much does a HSS10x10x1/4 weigh in kg?
48.6 kg per meter. A 6 m bar weighs 291 kg and a 12 m bar 583 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a HSS10x10x1/4?
About the strong axis, Ix = 141 in⁴ (5,869 cm⁴) with section modulus Sx = 28.3 in³. About the weak axis, Iy = 141 in⁴ and Sy = 28.3 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HSS10x10x1/4 or HSS10x10x3/8 — what does one size up change?
HSS10x10x3/8 is about 47% heavier (47.9 vs 32.63 lb/ft) but about 43% stiffer (Ix 202 vs 141 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
