KYA 50mm Galvanized Strapping Buckles are carbon steel wire buckles designed for compatible heavy-duty composite cord, woven and other suitable strapping systems. The featured KYA-80 model is 50mm (2") wide, manufactured from 8.0mm steel wire, and has a published 4500kg breaking load.
KYA lists galvanized and phosphated finishes for this buckle model. The published packing quantity is 100 pcs per box. For heavy-load applications, select the buckle together with the correct strap specification and tensioning equipment rather than selecting by buckle width alone.
The following specifications describe the featured KYA-80 heavy-duty wire buckle.
| Parameter | Specification |

The published 4500kg value refers to the KYA-80 buckle breaking load listed by KYA. It should not automatically be interpreted as the tested breaking strength of the complete strap-and-buckle system.
KYA publishes wire buckle models from 13mm through 50mm. The KYA-80 is the widest and highest published breaking-load configuration in the current product table.
| Model | Width | Wire Diameter | Pcs/Box | Breaking Load | Finish |
|---|---|---|---|---|---|
| KYA-30 | 13mm (1/2") | 3.3mm | 1,000 | 453kg | Galvanized / Phosphated |
| KYA-35 | 16mm (5/8") | 3.5mm | 1,000 | 659kg | Galvanized / Phosphated |
| KYA-40 | 19mm (3/4") | 4.0mm | 1,000 | 855kg | Galvanized / Phosphated |
| KYA-50 | 25mm (1") | 5.0mm | 500 | 1237kg | Galvanized / Phosphated |
| KYA-60 | 25mm (1") | 6.0mm | 500 | 1557kg | Galvanized / Phosphated |
| KYA-70 | 32mm (1-1/4") | 7.0mm | 250 | 2439kg | Galvanized / Phosphated |
| KYA-70A | 38mm (1-1/2") | 7.0mm | 150 | 3596kg | Galvanized / Phosphated |
| KYA-80 | 50mm (2") | 8.0mm | 100 | 4500kg | Galvanized / Phosphated |
A buckle with a higher published breaking load should not automatically be substituted for another model. Strap width, strap construction, buckle geometry, wire diameter and the complete securing requirement all need to match.
Request Wire Buckle Specifications
KYA lists both galvanized and phosphated surface options for KYA-80 and the wider wire buckle range. Specify the required finish when requesting a quotation.
Galvanizing provides corrosion protection compared with uncoated carbon steel. The actual suitability of a galvanized buckle depends on moisture, chemicals, temperature, storage conditions and exposure duration.
Phosphated buckles may be specified as part of a particular strapping configuration. Where system performance depends on a tested buckle finish, use the specified component rather than substituting another finish without confirmation.
KYA’s published company information describes more than 20 years of experience, an automated production process and customers in over 50 countries. The product information states that buckle production is backed by SGS and TÜV certification. Buyers requiring certification should request current reports and confirm that they cover the selected model, finish and intended strapping system.
The published delivery information lists shipment from Qingdao within 20–30 days after deposit. Confirm the current production schedule, shipping terms and destination-specific delivery estimate when ordering.
KYA lists custom buckle sizes and specifications. Provide the required width, wire diameter, finish, strap type and quantity so the configuration can be confirmed.
KYA describes the galvanized or phosphated finish as corrosion resistant for demanding outdoor conditions. Actual performance depends on coating, exposure duration, salt, chemicals and storage; confirm suitability for marine or other severe environments before ordering.
The published product information describes a self-locking buckle design intended to resist slippage and allow easy threading with a compatible tensioner. Correct threading, matching strap dimensions and controlled tension remain essential to the complete joint.
The 4500kg value published for KYA-80 is the breaking-load specification listed for the buckle itself. A complete strapping system also includes the strap, buckle engagement, threading arrangement and applied tension.
The system breaking strength can therefore differ from the standalone buckle value. For heavy-duty cargo securing, do not use the 4500kg buckle rating as a substitute for a tested complete-system rating unless supporting documentation confirms the relationship.
Where a project specifies a minimum securing or system-breaking requirement, confirm the exact strap, buckle and tensioning configuration before ordering.
KYA's current product information identifies the wire buckle range for use with polyester cord strapping, woven lashing and other compatible strapping materials.
For the KYA-80, confirm that the selected strap is suitable for the 50mm buckle width and the required load. Strap construction, thickness and required applied tension can affect the joint even when the nominal strap width is 50mm.
When replacing an existing buckle, provide the current strap specification, buckle width, wire diameter and required system performance for comparison.
The KYA-80 is the largest wire buckle configuration in the currently published KYA range and is intended for compatible heavy-duty industrial strapping applications.

Heavy-duty woven and composite strapping systems
For transport or cargo-securement applications, calculate the required securing forces and verify the complete strapping system. Buckle breaking load alone is not sufficient for selecting a cargo-securing system.
Thread the compatible strapping through the buckle according to the required threading pattern. Position the strap around the load and use tensioning equipment suitable for the strap material, width and required applied tension.
Check that the strap is correctly seated around the buckle before releasing the tensioning equipment. The joint should remain correctly positioned after tension is applied.
Do not exceed the operating limits of the strap, buckle, tensioning equipment or packaged product. Use suitable edge protection where sharp or abrasive load surfaces could damage the strapping.
KYA-80 is the published 50mm (2") buckle configuration. Confirm the actual width of the strapping before selecting the buckle.
The KYA-80 is manufactured from 8.0mm wire. When replacing an existing buckle, compare both buckle width and wire diameter.
KYA publishes a 4500kg breaking load for KYA-80. If the project requires a specified complete strap-system strength, obtain confirmation for the selected strap-and-buckle combination.
Specify galvanized or phosphated finish when ordering, especially when matching a previously approved strapping configuration.
Heavy-duty 50mm strapping requires equipment designed for the selected strap construction, width, thickness and required tension. Do not assume compatibility based only on the nominal 50mm size.
Heavy industrial loads may have sharp, rough or abrasive contact points. Use suitable edge protection where required to reduce the risk of strap damage.

KYA-80 is a 50mm (2") steel wire buckle manufactured from 8.0mm wire.
KYA publishes a 4500kg breaking load for the KYA-80 buckle.
Not automatically. The 4500kg figure is published for the buckle. Complete system performance also depends on the strap, buckle engagement, threading arrangement and applied tension.
The published packing quantity for KYA-80 is 100 pcs per box.
KYA lists galvanized and phosphated finishes for KYA-80.
KYA identifies the buckle range for compatible polyester cord, woven and other suitable strapping systems. For KYA-80, confirm the exact 50mm strap construction, thickness and required performance before ordering.
KYA-70A is 38mm wide with 7.0mm wire and a published 3596kg breaking load. KYA-80 is 50mm wide with 8.0mm wire and a published 4500kg breaking load.
Within the current 13mm–50mm table on this product page, KYA-80 has the highest published buckle breaking load at 4500kg.
Galvanizing provides corrosion protection compared with uncoated carbon steel. Actual performance depends on exposure duration, moisture, chemicals and the service environment.
Outdoor suitability depends on the selected surface finish, duration of exposure and environmental conditions. Confirm the required corrosion protection for the intended application.
A suitable tensioning tool is normally used to apply controlled tension to the strapping. The equipment must support the selected strap material, width, thickness and required tension.
Do not substitute buckle models solely to obtain a higher published breaking load. Buckle width, wire diameter, strap dimensions, joint geometry and the complete system requirements must all match.
KYA also supplies polyester composite cord strapping for compatible wire-buckle systems. Match the strap, buckle and tensioning equipment according to the required complete-system performance.
