Rectangle Structural Tube Per. ASTM 1085, table chart HSS Hollow Structural Section Square Structural Tube. This specification covers cold-formed welded carbon steel hollow structural sections (HSS) for welded or bolted construction.

Where:

h = Height
w = Width
t = Wall thickness
I = Area moment of inertia
S = Elastic section modulus
Z = Plastic section modulus
J = Torsional stiffness of cross section
C = Tortional shear constant or cross section
A = Section area
r = Radius of Gyration

Notes:

  • Cold formed and welded
  • Yield Stress Round 50 ksi min - 70 ksi max
  • Tensile stress 65 ksi min
  • Wall thickness -5%
  • Mass tolerance -3.5%
  • CVN 25 ft-lbs at 40 degrees F
  • Heat treating optional
