2. Consistency and Precision Manual straightening of rebar often leads to inconsistencies in length and straightness. In contrast, rebar coil straightening machines offer a high degree of precision. With computerized controls, these machines can produce rebar that meets tight tolerances, which is critical for ensuring the structural integrity of concrete projects.
4. Annealing Following the cold rolling process, the steel strips may require annealing. This heat treatment process relieves internal stresses that develop during cold rolling, restoring ductility and reducing hardness. The annealing process can be performed in a continuous furnace where the steel strip is heated and then gradually cooled.
