How to Calculate Weight of Reinforced steel Rod

Reinforcement Steel

Usually 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm, 40mm dia size of reinforced steel bar used in construction, in this bars 6mm & 8mm are called as plain bar and 12mm, 16mm, 20mm, 25mm, 32mm, 40mm bars are called as rebar (or) Torsion bar , usually standard length of one reinforced steel bar is 12m.

Plain bar:-  The steel bar is don’t have rip which is called as plain bar

Torsion / Rebar:-  The steel bar having a rip which is called as torsion or rebar

Formula to find weight of reinforced steel rod / unit weight of steel bars.

         Formula = D²/162, ( D-Diameter of steel bar )

Unit Weight calculation of Steel bar @ 1m Length

Unit Weight of 6 mm Steel bar  =  6² /162    =   0.22 kg/m

Unit Weight of 8 mm Steel bar  =  8² /162    =   0.395 kg/m

Unit Weight of 10 mm Steel bar =  10² /162  =  0.617 kg/m

Unit Weight of 12 mm Steel bar =  12² /162  =   0.889 kg/m

Unit Weight of 16 mm Steel bar =  16² /162  =   1.580 kg/m

Unit Weight of 20 mm Steel bar =  20² /162 =   2.469 kg/m

Unit Weight of 25 mm Steel bar =  25² /162 =    3.858 kg/m

Unit Weight of 32 mm Steel bar =  32² /162 =   6.321 kg/m

Unit Weight of 40 mm Steel bar =  40² /162 =   9.877 kg/m

Standard length of one reinforced steel bar is 12m so,

Unit Weight Of Steel Bars
