Products are defined by core values.

Anti-tampering steel wire seal is a high-security sealing tool with high-strength steel wire as the main body and a metal or composite lock body. It realizes anti-tampering, anti-theft, and traceability management for goods and equipment through a unidirectional locking mechanism and destructive demolition characteristics. It is suitable for scenarios with extremely high security requirements. Compared with plastic seals, the tensile strength of steel wire seals is increased by 3-10 times, and it can withstand a tensile force of 200-2000N, making it a "safety barrier" in customs, finance, energy, and other fields.

Core structure and tamper-proof technology

1. 3D lock system· Steel wire main body: Adopt galvanized steel wire, diameter 1.8mm, the surface is antirust treated, salt spray test can reach more than 1000 hours;

· Lock structure: Cast of aluminum or zinc alloy, built with multi-toothed cranes + anti-knock-on design, automatically locks after the wire is inserted. Forced pull will cause the lock to break or the wire to deform, leaving a trail of irreversible damage;

· Counterfeit marking: supports laser engraving unique codes, QR codes, and barcodes to achieve digital tracing of origins.

2. Core technologies for tamper prevention

· Damage recognizability: The lock body adopts fragile design, violent dismantling will cause the "OPEN" word exposure or code damage, visible to the naked eye;

· Mechanical anti-desertion design: the angle of the wire and the lock is 120 °, and the lock will automatically crack when the horizontal pull exceeds the threshold, avoiding being pryed open by professional tools;

· Tracking ID: Part of the steel wire seal bar code can track the direction and positioning of the goods by scanning the code, locking the goods will not be lost.

Material and technology

Galvanized steel wire: high strength, acid and alkali resistance, suitable for shipping, chemical scene; Galvanized steel wire: low cost, good rust resistance, suitable for land logistics.

Customized service

· Custom coding: supports 4-8 digit/letter combinations, laser engraving of company logo;

· Customized security level: Adjust the breaking force of the lock body according to the requirements (e.g., customs seals need to comply with ISO 17712 standards);

Intelligent upgrade: integrated barcode positioning, tracking communication module, real-time monitoring of seal status (suitable for escort vehicles).

Scenario application case

1. Cross-border logistics and customs regulation

· Application: Shipping container, cross-border truck sealing, in line with WCO (World Customs Organization) standards;

· Advantages: Breaking force ≥ 500 N, laser coding can be traced through the customs system to prevent the goods from being tampered with during transit.

2. Finance and Precious Goods Shipping

· Applications: bank money carriers, jewelry carriers and electronic device seals;

· Technology: The dual lock interlocking design requires special tools to remove, and the barcode scan and location tracking can achieve the full-scale monitoring of the shipping.

3. Energy and utilities

· Applications: lead seals for tanker trucks, valve locking for natural gas pipelines, meter block seals;

· Features: temperature resistance - 40 ° C to 120 ° C, anti-acid and alkaline corrosion, suitable for complex outdoor environments.

4. Military and Confidential Materials Management

· Applications: Ammunition boxes, confidential file boxes sealed;

· Custom: Made of magnetic-resistant stainless steel, the coding needs to be checked with the encryption system, and the damage traces can be identified by microscopy.

Guide to use and maintenance

1. Operating procedures

· Installation: Pass the steel wire through the sealing hole and insert it into the lock body until it cannot be pulled;

· Disassembly: Use special pliers to cut the steel wire (it is forbidden to use hammers and other tools to strike the lock body, to avoid shrapnel flying).

2. Notes

· Storage: Dry and ventilated environment, avoid contact with strong acids and alkalis;

· Disabled scenes: Repeated use is prohibited, and the lock body should be scrapped immediately if it is deformed or the code is unclear;

Emergency handling: If the seal is found to be damaged abnormally, it is necessary to preserve the on-site evidence and notify the regulatory authority at the first time.
