Deformed Steel Rebar
11 month ago
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.

Application
Steel rebar are mainly subjected to tensile stress in concrete. The deformed steel bar has a greater bonding ability with concrete due to the action of the ribs, and thus can better withstand the external force. Rebar is widely used in various building structures. Especially large, heavy, lightweight thin-walled and high-rise buildings.
