To calculate weight manually, bring dimensions of the steel sheet to meter, as steel's weight is given as kilogram/square meter.
Thus; Length in meter times width, in meter times wall thickness in meter, multiplied by the weight of steel per square meter.
Refer to the table below
|<4.5 Wall||Length/1000||Width/1000||Wall Thickness/1000||8039|
|>4.5 Wall||Length/1000||Width/1000||Wall Thickness/1000||
For example, a sheet given with dimensions of 3500x2500x4.0's weight would be calculated as follows: (3500/1000) X (2500/1000) X (4/1000) X 8039 = 281.37 kg's.
ID= O.D (Outside Diameter of steel tube) - 2 times the wall thickness.
Mass of a Round Steel Tube:
(OD - Wall Thickness) X Wall Thickness X 0.02466.
For Example a 60.3x4 round tube will be calculated as follows
(60.3-4) X 4 X 0.02466 = 5.55 Kg/meter.
Mass of a Square or Rectangular Steel Tube:
Determine the size of the 'mother' (input tube). As each welded square and rectangular tube are formed from a mother tubes which is round.
Thus take ((side A + side B) X 2)/ 3.142
A 100x60 rectangular steel tube's mother tube, will be determined as follows:
((100 + 60) X 2)/3.142 = 101.8, thus the mother tube will be a 101.6 round tube. (Closes available round steel tube.
Then proceed with the calculation on the on the mass of a round steel tube.
