Lead-core rope is a type of rope woven from synthetic fibers (such as Polypropylene, Polyethylene, etc.) and has a lead core inside to increase its weight, making it easier to sink underwater. It is commonly used as the bottom line of fishing nets. Specifically, what is lead-core rope, its advantages and disadvantages, applications, and where to buy reliable lead-core rope will be explored in the following article.

1. What is Lead-Core Rope?

Lead-core rope is a type of rope commonly woven from synthetic fibers such as polypropylene, polyethylene, etc., with a lead core inside. Lead, being a soft, malleable metal, is highly suitable for use as the core of the rope as it can easily be threaded inside the synthetic fibers.

Common types of lead-core ropes include:

  • PP 4-strand lead-core rope
  • PP 8-strand lead-core rope

The number of lead cores in each rope depends on the customer's needs as well as the manufacturer's design. Typically, the number of lead cores corresponds to the number of strands in the rope, with each strand having one lead core inside.

Here are some common specifications for lead-core ropes:

  • Diameter: Approximately 10 - 50mm. The diameter is usually larger than that of ropes without a lead core.
  • Strands: 4 strands, 8 strands.
  • Color: Light brown or according to customer requirements. The color durability ensures that the product does not fade during use.
  • Number of lead cores: 4, 6, 7, 8, 12, 16, etc.
  • Weight (gram/meter): Approximately double that of lead-free PP ropes.
  • Breaking strength: Nearly equivalent to the breaking strength of lead-free PP ropes.

2. Outstanding advantages of lead-core rope

Using lead as the core in the rope provides many outstanding advantages compared to ropes without a lead core:

  • High durability, good resistance to abrasion.
  • Less prone to wear, rot.
  • Resistant to high temperatures, not affected by oil and not soluble in any chemicals.
  • Heavier rope weight makes it easier to sink.
  • Less prone to twisting, kinking, and strand breaking compared to lead-free PP ropes.

3. Applications of lead-core rope

Due to its heavier weight compared to regular PP ropes, lead-core rope has specific applications:

  • In the mining and fishing industry: for boat anchoring, tying boats, bottom lines for fishing nets, etc.
  • Maritime transport: for mooring lines, tying, cable lifting, etc.
