Tamper Evident Cable Seals are single-use security devices that combine a flexible steel cable with a locking body to protect cargo and equipment against unauthorized access.
Our Tamper Evident Cable Seals are designed for logistics operators, distributors, and industrial users who require stronger protection than standard plastic seals. Manufactured with multi-strand galvanized steel cable, durable locking components, and controlled identification marking, these cable seals provide a practical solution for securing shipping containers, trailers, rail freight, warehouses, and industrial equipment.
As a professional security seal manufacturer, we supply OEM and bulk solutions with customized numbering, logo marking, packaging options, and consistent production control to support long-term supply requirements.
Key Advantages
Durable Steel Cable Construction for Demanding Applications
The cable structure directly affects the security performance and service reliability of a seal.
Our cable seals use high-strength galvanized steel cable, providing:
Strong resistance against pulling forces during transportation
Improved durability compared with plastic-only sealing products
Better performance in outdoor and long-distance shipping environments
Flexible installation for different locking points
Different cable diameters are available depending on the required security level and application environment.
For example:
Smaller cable diameters are commonly used for general cargo control
Larger diameter cable seals are suitable for higher-security transportation applications
Secure Locking Mechanism with Visible Tamper Evidence
A security seal should not only stay locked during transportation but also allow operators to quickly identify possible unauthorized access.
Our cable seals feature a one-way locking design that:
Holds the cable securely after installation
Prevents normal removal without damaging the seal
Provides clear visual evidence after opening attempts
Supports faster inspection procedures at transfer points
This helps logistics teams improve cargo control without adding complicated operating steps.
Controlled Numbering System for Supply Chain Traceability
For many logistics and industrial customers, identification management is just as important as physical security.
Each seal can be supplied with customized identification options, including:
Sequential serial numbers
Laser marking
Company logos
Barcodes
QR codes
A controlled numbering system helps customers:
Match seals with shipment records
Improve internal tracking procedures
Manage large inventory volumes
Reduce identification errors during distribution
During production, numbering information is verified according to customer requirements to maintain consistency across bulk orders.
Stable Bulk Manufacturing for Long-Term Supply
For distributors and large users, product consistency is critical.
A reliable security seal supplier should provide:
Stable locking performance between batches
Consistent cable specifications
Accurate serial number management
Repeatable production quality
Our manufacturing process is organized around standardized production procedures and inspection checkpoints to support repeat orders and large-volume supply programs.
