- High-Frequency Electric Resistance Welding (ERW) In this method, electrical currents are passed through the edges of the metal strips to heat them, allowing them to fuse together under pressure. This technique is highly efficient and produces a continuous weld along the length of the pipe.
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.
