High Tensile Prestressed Steel Strand
Product Overview:
The prestressed steel strands commonly used in prestressed steel strands are uncoated low-relaxation prestressed steel strands, which are often used in bridges, construction, water conservancy, energy, and geotechnical engineering.
High Tensile Prestressed Steel Strand Details
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. (reel-less) finished.
