Rebar Sizes of Different Standards

As we know, different countries have their own way to measure and record the reinforcing bar. To meet the needs of our customers, we display some rebar sizes charts so that it is easy to choose the most suitable rebar you wanted.

Customized sizes according to your requirements are also available.
