HOW TO CALCULATE STEEL WEIGHT IN KG

STEEL WEIGHT CALCULATION

STEEL QUANTITY:

  • The weight of the bar in kg/meter should be calculated as (d2 ÷ 162) where‘d’ is the diameter of the bar in mm.
  • ‘L’ for column main steel in footing should be considered as a minimum of 30cm/as specified.
  • For bent bar add 0.42d in straight length of the bar where‘d’ is the clear depth of beam/slab.
  • For the cantilever, beam anchorage length for main steel should be 69D or the length of the cantilever whichever is greater.

Weight per meter of different dia of steel bar.

  • 6    = 0.222 kg per meter
  • 8    = 0.395 kg per meter
  • 10 = 0.617 kg per meter
  • 12 = 0.888 kg per meter
  • 16 = 1.58 kg per meter
  • 20 = 2.469 kg per meter

With help of this formula, you can find any type of dia bar weight

(d2 ÷ 162)

Where

D = diameter of bar in mm.

Calculate the number of stirrups in the column or beam

  • Number of Stirrups = (clear span/spacing) + 1
  • The lap length in the column should be 45D

Where

D = diameter of bar in mm

  • Lap length in beam/slab should be 69D

Where

D = diameter of bar in mm

For example- let’s Calculate 12mm Dia Bar Weight For 2 Metre Length with help of this Formula (d2 ÷ 162).

(12×12)/162 X 2  ( Dia x Dia)/162x Lenght of bars

144/162*2

The total bar weight is 1.7777 KG for 2 Metre Length.

    Great article. To calculate cost, weight or length of elements: rod, pipe, profiles/sections (L, C, I/H, T) based on the dimensions given by You or by standards (EN, DIN, GOST).
    Built-in database of 30+ materials: metals (e.g. steel, aluminum, gold) and others (e.g. rubber, ice, cork).
    You can use Material Weight Calculator –

    Very informative part of Civil Engineering. Rebar elements form a major part of Concrete Reinforcement and it is vital to know how to calculate Tonnages involved.

    I will, in due course, contribute some formula details for Rebar weight calculation having worked for many years on Mine related Construction Capital Projects where Rebar weight calculation was key in Contract Reconciliation, e.t.c.
