Square 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
