I present to you a very simple and easy to use calculator valves. On this calculator you can easily calculate the mass of reinforcement or rebar length.

Operating procedure:
1. Select the calculation type "calculation of masses by a length" or "length calculation by mass"
2. Set the armature diameter
3. Set the length / weight
4. If necessary, press "calculate the cost" and set the valves cost per tonne
5. Press the "Calculation"

For reference:

- according to GOST 5781-82 "Hot-rolled steel for reinforcement of concrete structures" armature meets the following diameters: 6, 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40, 45, 50 , 55, 60, 70, 80 mm.

- density became 7850 kg / m3
