What Is Rebar Size and Rebar Diamters?
The Rebars are steel reinforcement bars that are used with concrete to improve the tensile strength of concrete. Because, it is a known fact that concrete is very weak in handling tension force, but is strong in handling concrete forces which are acting on any structure.
There are various Reabr Size and Rebar Diameter Used in construction as per work and conditions.

Steel is the only material used as Rebar in concrete because its elongation at high temperature is nearly the same as that of concrete.
