Polyester Composite Cord Strap is a polyester load-securing strap with high-tenacity yarns encapsulated in a polymer coating. It is used with wire buckles and tensioning tools to secure heavy, irregular and surface-sensitive cargo for road, rail, container and ocean transport.

Product Performance
High Strength: Parallel high-tenacity polyester yarns form the load-bearing structure, delivering 280–2,000 kg linear breaking strength for different cargo loads.
Low Elongation: The high-tenacity filament structure limits elongation to below 10% under working load, helping maintain restraint tension during transport.
Low Surface Damage: A smooth polymer coating covers the polyester yarns, reducing direct abrasion between the strap and painted or coated cargo surfaces.
Corrosion-Free: The strap uses polyester yarn and polymer coating instead of exposed steel, eliminating rust from the strap itself and sharp metal edges during handling.

Composite cord strap is suitable when cargo protection, corrosion resistance and flexible load securing are priorities.
Buckle & Tensioning System
Buckle: Heavy-duty steel wire buckles matched to the strap width.
Tensioner: Manual cord strap tensioners are used to apply tension before cutting the strap.
System Matching: Strap width, buckle size and tensioning tool must be matched as one securing system.
Application: The strap is passed around the cargo, threaded through the buckle, tensioned and then cut.
Applications
Steel & Metal: Steel coils, aluminum profiles and metal pipes where surface contact needs to be controlled.
Timber & Wood: Logs, engineered lumber and plywood packs during road or container transport.
Machinery & Equipment: Pumps, machinery and heavy components secured on trailers or flat-rack containers.
Construction Materials: Concrete blocks, bricks and ceramic tiles bundled for transportation.
Container Cargo: Heavy palletized or irregular cargo requiring additional restraint during transit.

Quality Control
Width & Core Check: Each production batch is checked for strap width and 200/400 mm core diameter to ensure consistent fit with the specified buckle, tensioner and dispenser.
Breaking Strength Test: Finished strap samples are tensile-tested to verify the specified 280–2,000 kg linear breaking strength before shipment.
Elongation Test: Samples are tested under the specified load condition to verify elongation remains within the required range and to ensure consistent tensioning performance.
Coating Inspection: The polymer coating is visually inspected for exposed yarn, uneven coverage and surface defects that could affect handling or cargo contact.
Finished Roll Check: Roll length, winding condition, labeling and packaging are checked against the purchase order to prevent quantity and specification discrepancies.

FAQ
Q: Can polyester composite cord strap be re-tensioned after securing?
A: Yes. The strap can be re-tensioned with a compatible tensioning tool when cargo settles or restraint tension needs to be restored.
Q: How should composite cord strap be stored before use?
A: Keep rolls in their original packaging in a dry storage area and protect them from prolonged direct sunlight, moisture and physical damage.
Q: Does composite cord strap require special cutting tools?
A: No special metal-cutting equipment is required. The strap can be cut with a compatible cord strap cutter after tensioning.
Q: Can one strap roll be used for multiple cargo bundles?
A: Yes. The required cut length can be set for each bundle, allowing roll stock to be cut to the length required for individual loads.
Q: What should be checked when approving a new strap supplier?
A: Check the supplied strap against the agreed width, breaking strength, elongation, core size and packaging specification, then retain an approved sample for future batch comparison.
Q: How can buyers verify strap consistency between batches?
A: Use the approved sample and purchase specification as the reference for incoming inspection, with particular attention to width, breaking strength, elongation and coating condition.
