The manufacturing process is divided into monofilament manufacturing and stranded wire manufacturing. (Cold) wire drawing technology is used when making monofilament. According to different products, the material can be a high carbon steel wire rod, stainless steel wire rod, or medium and low carbon steel wire rod. Zinc shall be electroplated or hot-dipped on the monofilament. In the strand manufacturing process, a stranding machine is used to strand multiple steel wires into a product. The prestressed steel strand needs to be continuously stabilized after forming. The final product is generally collected on a reel or rolled without a shaft.
