HSS6x2x1/4 — Dimensions, Weight & Section Properties
Hollow structural section per ASTM A500 / AISC Steel Construction Manual
HSS6x2x1/4 is an American hollow structural section (HSS) 6×2 inches (152.4×50.8 mm) with a nominal 0.25 in wall, weighing 12.21 pounds per foot (18.2 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 HSS6x2x1/4 spanning 10 ft with a 10 kip point load at midspan deflects 0.95 in (E = 29,000 ksi, Ix = 13.1 in⁴). The L/360 serviceability limit for this span is 0.33 in — the shape does NOT pass this quick check.

Frequently asked questions
How much does a HSS6x2x1/4 tube weigh?
HSS6x2x1/4 weighs 12.21 pounds per foot (18.2 kg/m). A 20 ft bar weighs 244 lb and a 40 ft bar 488 lb.
What are the dimensions of a HSS6x2x1/4?
HSS6x2x1/4 is 6×2 in (152.4×50.8 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 HSS6x2x1/4 in mm?
HSS6x2x1/4 is 152.4×50.8 mm outside with a nominal wall of 6.4 mm. In metric section properties: Ix = 545 cm⁴, Sx = 72 cm³.
How much does a HSS6x2x1/4 weigh in kg?
18.2 kg per meter. A 6 m bar weighs 109 kg and a 12 m bar 218 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a HSS6x2x1/4?
About the strong axis, Ix = 13.1 in⁴ (545 cm⁴) with section modulus Sx = 4.37 in³. About the weak axis, Iy = 2.21 in⁴ and Sy = 2.21 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
