How much does the armature weigh?

Often, when buying metal products, novices can figure out the simplest things, such as size, weight, and other metric characteristics. For example, when purchasing an armature, you should know how to determine its weight.

How much does the armature of different diameter weigh

The indicator of how much the reinforcement weighs depends on:

  • the type of metal from which it is made;
  • the length of the rods and their diameter;
  • manufacturer, as this product can be manufactured according to GOST or according to the own technical conditions of the company (plant).

The diameter of the reinforcement according to GOST (steel grade A500C) can vary from 6 mm (the thinnest) to 40 mm thick (the thickest). Most often in the technical and commercial documents for the sale of this material is the weight of this product for 1 linear meter.

How much does the reinforcement meter weigh depending on the diameter

  • 6 mm - 0,222 kg;
  • 8 mm - 0.395 kg;
  • 10 mm - 0.617 kg;
  • 12 mm - 0.888 kg;
  • 14 mm - 1.21 kg;
  • 16 mm - 1.58 kg;
  • 18 mm - 2 kg;
  • 20 mm - 2.47 kg;
  • 22 mm - 2.98 kg;
  • 25 mm - 3.85 kg;
  • 28 mm - 4.83 kg;
  • 32 mm - 6.31 kg;
  • 36 mm - 7.99 kg;
  • 40 mm - 9.87 kg;
  • 45 mm - 12.48 kg;
  • 50 mm - 15.41 kg;
  • 60 mm - 22.19 kg;
  • 70 mm - 30.21 kg;
  • 80 mm - 39, 46 kg.

The weight of a meter of reinforcement can be independently calculated using a simple formula

1 mx (3.14 x D x D / 4),

where D is the diameter of the valve. The resulting figure should be multiplied by the specific weight of the reinforcing steel, which is equal to 7850 kg / m3. For example, if you need to calculate the weight of one meter of reinforcement with a diameter of 14 mm:

Volume: 1 meter x (3.14 x 0.014 m x 0.014 m / 4) = 0.00015386

Weight: 0.00015386 x 7850 kg / m3 = 1,207. If you round up to hundredths, the weight is approximately equal to the weight from the table above.
