Short for [reinforcing bar," rebar is refers to metal – usually steel – that`s used to help increase the tensile strength of concrete for a variety of needs, including many of the most common construction types you see every day.
Concrete is known to be weak in the areas we just mentioned, at least compared to steel and other metal types. If this reinforcement was not used, these structures would at-risk of falling apart.
Rebar usually will be built so the metal component is not visible within the structure. Rather, it will be buried within the concrete. It`s usually made with ribs rather than smoothly, allowing it to avoid slippage within its structure.
How Rebar is Made
As we noted above, the most common material for rebar use is steel, which is used because of its excellent tensile properties. It`s often made from forms of recycled steel, which will be melted down using an electric arc furnace, cooled using billets, and then stored until it`s needed.
From here, billets can be reheated to an elevated temperature and fed through extrusion tools, then necked down until its proper size is reached. Finally, it will be tooled to create the proper ribbing, which we noted above is in place to prevent slippage within concrete. Then it will be sheared to the proper length, and it`s ready to go.
