For example: 47*75* 1.2 theoretical weight aluminum square pipe.
Calculation formula: {4.7x7.5-(4.7-0.12x2) x (7.5-0.12x2)} x
Length of aluminum square tube (100cm) x 2.7g/cm3 = 775g/m.
Others can be calculated as follows: {length× width-(length -2× thickness )× (width -2× thickness) }× aluminum tube length (cm )× 2.7g/cm3 = aluminum tube weight (g).
Note: 2.7 g/cm3 is the density of aluminum.
Weight of square aluminum bar (kg) =0.0028× side width× side width× length.
Weight of square copper bar (kg) =0.0089× side width× side width× length.
Weight of square brass bar (kg) =0.0085× side width× side width× length.
Diamond plate aluminum: weight per square meter =2.96* thickness.
Aluminum pipe weight (kg) =0.00879× wall thickness× (outside diameter-wall thickness )× length.
Weight of aluminum plate (kg) =0.00 17 1× thickness× width× length.

Formula for calculating theoretical weight of square rectangular steel tube;
Square and rectangular (rectangular) section carbon steel pipes: weight per meter: kg/m (kg/m)&; Pound/foot (pound/foot)
The calculation formula of square rectangular tube is: (length+width) ×2÷3. 14- thickness× thickness× 0.02466 = kg/m.
Equation 2: kg/m = (Oc-4Wt) * Wt * 0.00785.
Where Oc is the outer circumference of the steel pipe and Wt is the wall thickness of the steel pipe; Square Oc = 4 * a；; The rectangle OC = 2A+2B A, and b is the side length, which is usually interpreted as 4x wall thickness x (side length-wall thickness) x7.85.
