Understanding Woven Strapping and Its Red or blue line Strength Indicators

Understanding Woven Strapping and Its Red or blue line Strength Indicators

Woven strapping is a durable and flexible alternative to steel strapping, widely used for securing loads in transport and storage. Made from high-tenacity polyester fibers woven together, it provides excellent resistance to moisture, abrasion, and shock absorption.

A key feature of woven strapping is the coloured lines woven into the material, which indicate the strapping's strength and size.

What Do the Coloured Lines Mean?

Manufacturers use color-coded lines to differentiate various strengths of woven strapping:

  • Black or Blue Lines – These indicate standard-duty woven strapping, suitable for lighter loads and general applications.
  • One Red Line – This signifies medium-duty strapping, offering higher break strength than standard-duty options.
  • Two Red Lines – This denotes heavy-duty strapping, designed for securing heavier loads with maximum durability.

These markings help ensure users select the appropriate strapping for their specific load requirements. However, since strength ratings can vary between manufacturers, it’s always best to check the product specifications.

Choosing the Right Woven Strapping

When selecting woven strapping, consider these factors:

  1. Load Weight – Ensure the chosen strapping has a break strength exceeding the load’s weight.
  2. Application Type – For heavier or irregularly shaped loads, opt for stronger strapping with red-line indicators.
  3. Environmental Conditions – Woven polyester strapping is ideal for humid or rough handling conditions where steel strapping may corrode or damage cargo.

By understanding these color-coded strength indicators, businesses can improve load security, reduce shipping risks, and ensure safe transportation.
