HSS10x6x1/2 — Dimensions, Weight & Section Properties
Hollow structural section per ASTM A500 / AISC Steel Construction Manual
HSS10x6x1/2 is an American hollow structural section (HSS) 10×6 inches (254×152.4 mm) with a nominal 0.5 in wall, weighing 48.85 pounds per foot (72.7 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 HSS10x6x1/2 spanning 16 ft with a 10 kip point load at midspan deflects 0.3 in (E = 29,000 ksi, Ix = 171 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 HSS10x6x1/2 tube weigh?
HSS10x6x1/2 weighs 48.85 pounds per foot (72.7 kg/m). A 20 ft bar weighs 977 lb and a 40 ft bar 1,954 lb.
What are the dimensions of a HSS10x6x1/2?
HSS10x6x1/2 is 10×6 in (254×152.4 mm) outside, with a nominal wall of 0.5 in. Note that A500 tolerances put the design wall at 0.93×nominal (0.465 in) — the section properties listed already account for this.
What are the dimensions of a HSS10x6x1/2 in mm?
HSS10x6x1/2 is 254×152.4 mm outside with a nominal wall of 12.7 mm. In metric section properties: Ix = 7,118 cm⁴, Sx = 562 cm³.
How much does a HSS10x6x1/2 weigh in kg?
72.7 kg per meter. A 6 m bar weighs 436 kg and a 12 m bar 872 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a HSS10x6x1/2?
About the strong axis, Ix = 171 in⁴ (7,118 cm⁴) with section modulus Sx = 34.3 in³. About the weak axis, Iy = 76.8 in⁴ and Sy = 25.6 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HSS10x6x1/2 or HSS10x6x3/8 — what does one size down change?
HSS10x6x3/8 is about 23% lighter (37.69 vs 48.85 lb/ft) but about 20% less stiff (Ix 137 vs 171 in⁴). Check deflection before downsizing — stiffness falls much faster than weight.
