Materials: Q235
Grade: CRB550
Common size: φ2mm-φ14mm
The cold steel rolled steel bar is meet to the standard BS4483,ASTM,AS/NZS 4671,DIN488,IS,etc.
Steel reinforcement bars (cold rolled steel bar)or rebars are used to improve the tensile strength of the concrete, since concrete is very weak in tension, but is strong in compression. Steel is only used as rebar because elongation of steel due to high temperatures (thermal expansion coefficient) nearly equals to that of concrete.
