Just imagine, if you want to order plain iron with 10 SNI certificates, but in terms of weight, the iron and the costs you spend don't match, you can lose!
This does not rule out the possibility that this can happen even though you have ordered concrete iron at sales from a well-known company.
The reason is because each reinforcing bar calculator produced by each factory has a different tolerance value (but make sure the tolerance is still in accordance with the SNI tolerance study).

Remember, reinforcing bar calculator is not round. The diameter of the reinforcing bar calculator has a tolerance value even though the size and the SNI mark are listed.

In order to produce a sturdy and beautiful construction, it is better for us to know how to determine the diameter of the reinforcing iron correctly.
Determining or measuring the diameter of the reinforcing iron can be done with a caliper & a calculation formula so that the diameter of the reinforcement is in accordance with the guidelines of the Indonesian Concrete Regulations.
This fast and accurate method applies to both plain and round iron bars.
We try to provide solutions for buyers to make it easier to check the original sketch of iron and beginner iron traders to make it easier to work in calculating the price of iron, which is usually the manufacturer's price every kilo and sold at a price every rod.
