WEIGHT FORMULA'S
TUBING
Stainless : (lbs./ft) = 10.68 W(OD - W)
Aluminum: (lbs./ft) = 3.6904W(OD-W)
OD = outside diamter , W = wall thickness
ROUNDS
Stainless Round Bar (lbs./ft) = 2.67036 (D)^2
Aluminum Round Bar:(lbs./ft) = .9227(D)^2
SQUARES
Stainless Steel: (lbs/ft) = 3.4 x (D)^2
Aluminum : (lbs/ft) = 1.1748(D)^2
HEXAGONS
Stainless Steel:(lbs/ft) = 2.9446(D)^2
Aluminum: (lbs/ft) = 1.0175(D)^2
OCTAGONS
Stainless Steel:(lbs/ft) = 2.8166(D)^2
Aluminum:(lbs/ft)= .9733(D)^2
FLATS
Stainless Steel:(lbs/ft) = 3.4(T)(W)
Aluminum (lbs/ft) = 1.1748(T)(W)
T = thickness , W = Width (in inches)
