Buckle & Tensioning System
Wire Buckle: Matching buckle for locking the strap after tensioning.
Manual Tensioner: For standard cargo-securing operations.
Pneumatic Tensioner: For higher-volume securing operations.
Edge Protector: Helps distribute strap pressure at sharp cargo edges.
System Matching: Buckle and tensioner should match the strap specification and required securing load.
High-Strength Performance
High Load Capacity: High-tenacity polyester yarn and polymer coating provide the tensile strength required for heavy cargo securing.
Controlled Stretch: The polyester cord structure limits elongation to <10% at break, helping maintain restraint under tensile load.
Flexible Restraint: The continuous cord structure conforms to irregular and bundled cargo, improving contact during transport.
Moisture Resistant: The polymer coating protects the polyester yarn from moisture, preventing rust-related issues during humid transport and storage.
Surface Protection: The non-metallic coated structure provides a softer contact surface than steel strapping, reducing surface marking.
Applications
Steel Pipes & Coils - Bundling steel pipes, coils and profiles for road, rail and container shipment.
Lumber & Timber - Securing stacked wood products before loading and during transit.
Marble & Granite - Holding stone slabs and blocks together without direct contact with steel strapping.
Precast Concrete - Bundling precast components and other heavy construction products for delivery to job sites.
Machinery & Equipment - Restraining generators, machines and fabricated assemblies on flatbeds and inside containers.
Quality Control
Breaking Strength: Finished straps are tensile-tested to measure the maximum load before break and verify compliance with the specified strength grade.
Width & Thickness: Each production batch is measured with calibrated gauges at multiple points to identify dimensional variation against the ordered specification.
Elongation: Tensile testing records the strap elongation at break and verifies that the result remains below the specified 10% limit.
Coating Integrity: The coated surface is visually inspected and rubbed for exposed yarn, peeling, cracks or uneven coverage that could affect strap handling.
Strap Surface: Finished coils are checked for broken yarn, loose fibers, contamination and cuts under visual inspection before packing.
Coil Winding: Coil edges and layers are inspected for loose winding, uneven edges and deformation to prevent feeding or tensioning problems during use.
Batch Traceability: Production batch numbers are recorded against inspection results and shipment records for product traceability.
Cord Strap vs. Steel Strapping
|
Performance Metric |
Heavy Load Cord Strap |
Traditional Steel Strapping |
|
Weight & Handling |
Lightweight and flexible for manual tensioning, cutting and removal. |
Heavier and more rigid during handling and removal. |
|
Flexibility |
Conforms to bundled and irregular cargo surfaces. |
Rigid steel is less conformable around irregular loads. |
|
Corrosion |
Polyester does not rust during humid transport or storage. |
Steel requires corrosion protection when exposed to moisture. |
|
Cargo Contact |
Non-metallic strap surface reduces the risk of surface marking. |
Metal strapping can mark or damage finished surfaces without suitable protection. |
|
Removal |
Can be cut and removed without leaving rigid metal strap pieces. |
Cut steel remains rigid and requires careful handling |

FAQ
Q: Is cord strap suitable for painted or finished cargo?
A: Yes. Its non-metallic construction provides a softer contact surface than steel strapping.
Q: Can cord strap be used for container loading?
A: Yes. It is suitable for securing bundled and irregular cargo during container loading and transportation.
Q: How is cord strap packed for export shipment?
A: The strap is supplied in continuous coils and packed in export cartons with palletized shipment.
Q: Can the same strap be used with different buckle types?
A: Use the buckle specified for the corresponding cord strap system to ensure proper locking after tensioning.
Q: Is cord strap suitable for repeated handling during loading and unloading?
A: Yes. The flexible polyester structure can be tensioned, cut and removed during normal cargo handling operations.
Q: Can cord strap be used as a replacement for steel strapping?
A: It can be used for suitable heavy-cargo securing applications where a flexible, non-metallic strapping system is required.
