[0002] Rebar refers to steel used in reinforced concrete and prestressed concrete. Its cross-section is round, or sometimes square with rounded corners. It includes plain round bars, ribbed bars, and twisted bars. Rebar for reinforced concrete refers to the straight or coiled steel used for concrete reinforcement. It comes in two shapes: plain round bars and deformed bars, and is delivered in straight bars or coils. Over time, rust will form on the surface of rebar. If this rust is not treated, it will affect the rebar's usability.

[0034] Reference Figure 5The side surface of the U-shaped plate 12 is fixedly connected to the rust removal box 7, and rust removal liquid is provided in the rust removal box 7.
