Nominal diameter of deformed bars are specified by standards.

Diameter of deformed bar is controlled from test :

1. measure the mass w in kg weighted to a precision 0.5 %

2. measure the length L in m to a precision 0.5 %

The equivalent diameter is nominal diameter of deformed bars and calcolation is by this formula :

Diamater = root square of ( 162.13 w / L )

How to Measure for a Round Bar Installation?

Shashwat Stainless is the top Round Bar Manufacturer in India. Round bars are cylindrical metal rods with various applications across different industries. The diameter of the bar should be determined before taking any measurements for a round bar installation. To guarantee uniformity, measure the diameter precisely many times along its length using a caliper or measuring tape. Measure the length of the bar that is needed for the installation as well. To guarantee a good fit and prevent any errors during the installation procedure, take exact measurements.
