Poly cord strapping, also known as polyester cord strapping, is a versatile and durable option for securing loads. It is made from polyester fibers woven together, providing a high level of strength and flexibility. Compared to other types of strapping, such as steel, polypropylene, and polyester plastic strapping, poly cord strapping offers several advantages and some limitations.
1. **Strength**: Poly cord strapping is strong and can handle heavy loads, but it is generally not as strong as steel strapping. Steel is the strongest option, ideal for extremely heavy or sharp-edged loads. However, poly cord strapping is often preferred for its ability to absorb impacts and maintain tension over time, which steel cannot do as effectively.
2. **Flexibility and Safety**: Poly cord strapping is more flexible than steel, making it easier to handle and apply. It is also safer to use, as it does not have sharp edges that can cause injuries. This flexibility allows it to conform to irregularly shaped loads better than steel.
3. **Weather Resistance**: Poly cord strapping is resistant to moisture, UV rays, and most chemicals, making it suitable for outdoor use and long-term storage. This is an advantage over polypropylene strapping, which can degrade under UV exposure.
4. **Cost**: While more expensive than polypropylene strapping, poly cord strapping is generally more cost-effective than steel, especially when considering the reduced risk of injury and damage to goods.
5. **Applications**: It is ideal for securing loads that require some give, such as lumber, bricks, and other building materials. It is also used in industries like agriculture and shipping.
In summary, poly cord strapping offers a balance of strength, flexibility, and safety, making it suitable for a wide range of applications, though it may not be the best choice for the heaviest or most demanding loads where steel would be preferred.
