Types of Preformed Spiral Strands

  Preformed spiral strands are generally made of metal wires or synthetic materials. Metal preformed strands typically use galvanized steel or aluminum alloy wires, offering excellent corrosion resistance and conductivity. Synthetic preformed strands are usually made of polyester fiber, which provides superior mechanical strength and durability.

  There are many types of preformed strands, which can be categorized by material into steel strands, aluminum strands, aluminum-steel strands, and hot-dip galvanized steel strands, or by structure into single-strand, multi-strand, and parallel strands. Different types of preformed strands have varying properties and characteristics, allowing for selection based on specific needs.
