Historically in Europe, rebar is composed of mild steel material with a yield strength of approximately 250 MPa (36 ksi). Modern rebar is composed of high-yield steel, with a yield strength more typically 500 MPa (72.5 ksi).Rebar can be supplied with various grades of ductility. Rebar may also be used to hold other steel bars in the correct position to accommodate their loads. 2  External steel tie bars can constrain and reinforce masonry structures, as illustrated by the Nevyansk Tower or ancient structures in Rome and the Vatican.
