A steel wire cable seal is a one-time high security locking device that combines a tamper-proof lock body and high-strength steel wire. It is widely used in ocean containers, logistics trucks, utility meter boxes, fuel tankers, warehouse doors and other high value applications that require strong anti-tampering and anti-theft protection. This is the key of the mechanism that is "irreversible once locked", providing irrefutable physical evidence of unauthorized access, and is a vital asset for global cargo transportation and supply chain security management.

Single-Use Tamper-Evident Lock Body: The lock's internal locking mechanism and outer housing are permanently destroyed when forced or opened without proper authorization, offering immediate and unmistakable evidence of tampering.

Unique Identifiable Tracking: Each seal has a global serial number, individually marked by high-precision laser engraving or long-lasting inkjet printing for a seamless traceability.

Flexible Material Choices: Offered in rugged plastics (ABS/PC) or premium metals (aluminum alloy) to meet a variety of security standards and operating requirements.
