How Is Rebar Made? - Contractors Steel
First thing to remember, rebar is reinforcing bar. Steel bars are used as rebar because the elongation of steel due to high temperatures (thermal expansion coefficient) nearly equals that of concrete. Therefore, rebar is incorporated to reinforce concrete and impart the tensile strength needed to make sure concrete stays in place.
