Strap & Buckle Selection
Select the buckle according to the strap width and required load level. The available sizes are matched as follows:
13 mm strap → 3.0 mm wire / 25 mm inner length
16 mm strap → 3.5 mm wire / 30 mm inner length
19 mm strap → 4.0 mm wire / 35 mm inner length
25 mm strap → 5.0 mm wire / 40 mm inner length
32 mm strap → 6.0 mm wire / 50 mm inner length
For load-critical cargo, the strap and buckle should be evaluated as a complete securing assembly rather than selected by buckle size alone.
Heavy Load Performance
Prevents Strap Back-Slip
Angled wire geometry increases strap contact as tension rises, reducing strap movement during vibration and cargo movement.
Maintains Buckle Shape
Cold-drawn steel wire and wire-bending forming maintain the buckle geometry under tensile load, keeping the strap engaged.
Limits Surface Corrosion
Galvanized treatment forms a zinc layer on the steel surface, reducing corrosion caused by moisture and salt exposure.
Reduces Strap Abrasion
Rounded wire contact areas reduce concentrated pressure on the strap during tensioning, limiting localized wear.
Material & Manufacturing
Carbon steel wire is formed by CNC automatic wire-bending equipment. The formed buckles are then cold-formed and treated with electro-galvanized or hot-dip galvanized coating. Batch inspection covers buckle dimensions and mechanical performance before shipment.
Applications

aterial & Manufacturing Process
FAQ
Q: How do I use a cord strap buckle?
A: Thread the polyester cord strap through the buckle, then tension the strap with a compatible cord strap tensioner. The buckle locks the strap by friction as tension is applied.
Q: Can I order samples of Heavy Load Cord Strap Buckles?
A: Yes. Samples can be requested for product evaluation and strap-buckle fit testing before a bulk order.
Q: Can I use the buckle with both woven and composite cord strap?
A: Yes. This buckle series is designed for polyester woven strap and composite cord strap systems.
Q: How should I store cord strap buckles before use?
A: Store the buckles in a dry, covered area and keep the original packaging closed to limit exposure to moisture during storage.
Q: Can you provide product and shipping documents for import clearance?
A: Yes. Export documentation can be provided for international shipments and customs clearance.
Q: Can you supply mixed buckle sizes in one order?
A: Mixed sizes can be arranged for orders requiring more than one buckle specification.
Q: Can I reorder the same buckle specification for repeat shipments?
A: Yes. Anpack can supply repeat orders using the same approved product specification and packaging requirements.
Q: What should I provide when requesting a quotation?
A: Provide the required strap specification, buckle model or size, order quantity and packaging requirements. This allows the quotation to be matched to the required buckle configuration.
