Rebar is a steel strip, a type of building material. For example, in reinforced concrete, it is used to support the skeleton of the structure. Rebar is tensile but not compressive, while concrete is compressive but not tensile. The combination of the two has good mechanical strength. Rebar is protected by concrete and does not rust. Moreover, rebar and concrete have approximately the same thermal expansion coefficient, so they are less likely to crack and corrode. Therefore, it has become an ideal material for modern buildings and a widely used reinforced concrete building.

Types of steel bars:

Flexible steel bars (ordinary steel bars): plain round steel bars, threaded steel bars, herringbone steel bars; flexible steel bars are tied with iron wires, welded into steel mesh, and made into plane or space skeletons for pouring concrete in the formwork.

Strong steel bars: skeletons welded from various steel sections, rails, etc.

By chemical composition:

Carbon steel bars (low carbon, carbon content less than 0.25%; medium carbon, carbon content 0.25%~0.6%; high carbon, carbon content greater than 0.6%)

Low alloy steel bars (a small amount of silicon, manganese, titanium or rare earth elements is added to low carbon or medium carbon steel bars)

Production methods:

Hot-processed steel bars: hot-rolled steel bars, heat-treated steel bars

Cold-processed steel bars: cold-drawn steel bars, cold-drawn steel bars
