Product overview: the core barrier of mechanical anti-theft

The container screw seal is a high-strength mechanical locking device specifically designed for cargo containers, featuring a metal screw as its main component. By tightening the screw with a nut, a non-removable physical sealing structure is formed. Its core function is to prevent containers from being illegally opened during transportation, and due to the metal's resistance to damage and the stability of the mechanical locking mechanism, it serves as the "final line of defense" for the security of goods in maritime and land transportation. Compared to ordinary plastic seals, the screw seal's tensile strength is enhanced by 5 to 10 times, making it suitable for high-value goods, hazardous materials, and containers requiring long-distance transportation across regions.

Core purpose: to cover freight safety across the whole chain

1. International Maritime Transport and Container Logistics

· Ocean freighter container sealing: prevents pirates and dockmen from taking out the containers privately and stealing, especially for high-priced goods such as electronics, luxury goods, auto parts and other goods;

· Cross-border land freight container closure: apply seals after customs inspection to ensure that goods meet regulatory requirements in cross-border transport and avoid interchange.

2. Storage and freight vehicle management

· Storage of large warehouse containers: marked with "counted" status to prevent unauthorized access to internal goods during storage;

· Freight truck compartment sealing: In long-distance transportation, avoiding the loss of goods due to driver or third party factors is commonly used in cold chain logistics and FMCG transportation scenarios.

3. Transport of Special Goods and Dangerous Goods

· Seals for chemical raw materials and fuel containers: to prevent leakage or human tampering that leads to safety incidents;

· Transport of valuable machinery and equipment: Prove the integrity of goods before and after transport by physical locking, reducing disputes over cargo losses.

Core characteristics of the product: technical logic of mechanical anti-theft

1. High-strength metal structure design

· Screw body: Adopt galvanized steel, tensile strength of 500-800N, can resist the violent dismantling of hydraulic shears, wrenches and other tools;

· Bite-bite groove: The surface of the screw is carved with a tight anti-detachable groove, which forms a "wedge effect" after being screwed tight with the nuts. Forcible dismantling will cause the groove to deform and leave a clear mark of damage.

2. Resistance to natural weathering and acclimatization

· Anti-salt fog corrosion: Through a 500-hour salt fog test, it is suitable for humid marine transport environments;

· Temperature difference range: - 40 ° C to 120 ° C without deformation in environments, suitable for polar transport or tropical high temperature scenarios.

3. Traceability and anti-counterfeit marking

· Laser engraving: each seal is printed with a unique number and the company's English and Chinese language, which facilitates the tracing of origins in the logistics process;

· Anti-replication design: The numbered font uses a special laser etching process, which is difficult to copy, and the logistics system record can realize the "seal-transportation-unseal" tracking process.

4. Convenience of installation and removal

· Installation steps:

1 Remove the screw through the door lock or seal slot of the container;

2 Press the nut until it cannot be turned, and hear a "click" to complete the lock;

· How to dismantle: Use special scissors (such as hydraulic scissors) to cut the screw, which cannot be reused after damage to ensure one-time anti-counterfeiting.

Quality Detection and Reliability Verification

1. Physical Performance Testing

· Tensile test: The structure is kept intact under 2000 N tensile force, and the screw does not break or deform;

· Impact resistance test: 1 metre high fall freely to the concrete floor, with no loosening at the bite of the screw.

2. Environmental simulation testing

· High temperature and high humidity test: placed for 72 hours at 80 ° C and 95% humidity, with no rust on the metal surface;

· Low temperature resistance test: After 24 hours of freezing in an environment of -40 ° C, the screw bends 15 ° without breaking.

Aftermarket service and customization

1. Warranty & Aftersales

· Non-human quality issues: 1 year free return and exchange, lifetime technical support;

· Volume procurement services: Customized proprietary numbering rules (such as adding customer company codes, batch numbers) can be customized, and logistics management system docking solutions are provided.

2. Scenarios customization

· Special funds for customs supervision: printing customs supervisory markings and regional codes to meet cross-border transport compliance requirements;

· Corporate LOGO customization: Printing the brand identity through laser engraving or electrochemical corrosion process to enhance the brand exposure of logistics links.

Through the deep combination of mechanical structure and metal material, the container screw seal has become the core solution against man-made theft in the field of freight safety with the certainty of "physical anti-theft", especially suitable for logistics scenes with high requirements on sealing and traceability.
