The published 855kg figure refers to the KYA-40 buckle breaking load. It should not automatically be interpreted as the breaking strength of a complete strap-and-buckle system.
KYA publishes wire buckles from 13mm to 50mm. Each model has its own width, wire diameter, packing quantity and breaking-load specification.

KYA lists both galvanized and phosphated finishes for KYA-40. The required surface treatment should be specified when requesting a quotation.
Galvanizing provides corrosion protection compared with uncoated carbon steel. Actual suitability depends on moisture, chemicals, storage conditions and exposure duration.
Phosphated buckles may also be used where the selected strapping system specifies that buckle finish. Do not assume that different finishes are interchangeable in every tested strapping configuration.
KYA’s published company information describes more than 20 years of experience and states that wire buckle production is tested by SGS and TÜV. Buyers requiring certification should request current reports and confirm that they cover the selected model, finish and intended strapping system.
KYA describes the galvanized finish as protection against corrosion, seawater and weather exposure. Actual performance depends on coating, exposure duration, salt, chemicals and storage conditions; confirm suitability for the service environment before ordering.
The published delivery information lists shipment from Qingdao within 20–30 days. Confirm the current production schedule, shipping terms and destination-specific delivery estimate when ordering.
Samples and custom buckle sizes or specifications can be requested. Provide the required width, wire diameter, finish, quantity and application so availability can be confirmed.
The 855kg breaking load published for KYA-40 describes the buckle specification listed by KYA. The strength of a complete strapping system also depends on the selected strap, buckle engagement, threading pattern and applied tension.
Different 19mm strapping systems can therefore have different tested system-strength values even when the nominal strap and buckle widths are both 19mm.
If your project specifies a complete system breaking strength, provide the strap model, buckle model, surface finish and tensioning method for confirmation.
KYA lists KYA-40 for use with compatible 19mm composite cord strapping, woven cord strapping, hot-melt strapping and plastic strapping.
The selected strap should match the buckle width and should be suitable for the required tension and joint configuration. Nominal 19mm width alone does not guarantee compatibility because strap construction and thickness can also affect buckle engagement.
KYA-40 wire buckles can be used as part of compatible industrial strapping systems for bundling, palletizing and load securing.

Thread the compatible 19mm strapping through the buckle according to the required buckle pattern. Position the strap around the load and use a suitable tensioner to apply controlled tension.
Before releasing the tensioning tool, confirm that the strap is correctly seated around the buckle and that the joint remains stable under tension.
Trim excess strapping only after the joint has been correctly tensioned and checked. Use edge protection where sharp or abrasive load surfaces could damage the strap.
KYA-40 is the published 19mm (3/4") buckle model. Confirm the actual strap width before ordering.
KYA-40 uses 4.0mm carbon steel wire. Wire diameter is an important difference between buckle models and should be checked when replacing an existing product.
KYA publishes an 855kg buckle breaking load for KYA-40. If your project requires a tested complete-system strength, request the applicable strap-and-buckle system information.
Specify galvanized or phosphated finish when ordering, particularly when matching an existing strapping system.
Select a tensioner suitable for the strap material, 19mm width, strap thickness and required applied tension. Buckle dimensions alone do not determine tool compatibility.

KYA-40 is 19mm wide with 4.0mm wire and an 855kg published breaking load. KYA-50 is 25mm wide with 5.0mm wire and a 1237kg published breaking load.
Galvanizing provides corrosion protection compared with uncoated carbon steel. Actual service life depends on the environment, moisture, chemicals and exposure duration.
A compatible tensioner is normally used to apply controlled tension to the strapping. Select the tool according to the strap material, width, thickness and required tension.
Do not substitute buckles solely on nominal width. Compare wire diameter, finish, buckle geometry and the required strap-system performance before changing components.
KYA also supplies polyester composite cord strapping for compatible wire-buckle systems. Match the strap width, buckle dimensions and required load performance when selecting components.
