1. Improve the adhesion of the steel bar: the rib pattern on the surface of the cold-rolled ribbed steel bar is extruded by the roller, and the shape is clear and regular. This rib can increase the surface area of the steel bar, strengthen the bonding force and friction between the steel bar and the concrete, and greatly improve the adhesion of the steel bar.
2. Improve the anti-slip performance of steel bars: the rib shape and position of cold-rolled ribbed steel bars are precisely designed, which can form a good anchoring effect in concrete and improve the anti-slip ability of steel bars. This can not only improve the overall stability of the reinforced concrete structure, but also improve the seismic performance of the structure.
