Product Definition and Structure

Container screw seals are single-use metal anti-theft seals designed for containers and containers. The main body consists of stainless steel or alloy screws, nuts and lock caps. By screwing through the container lock hole, the nut is tightened, and the lock cap is stuck, forming an irreversible mechanical locking structure, and forced removal will cause the seal to break or deform, leaving a clear trail of damage.

Core uses

It is mainly used in sealing scenarios such as marine containers, land freight truck containers, large equipment containers for warehousing, etc. Preventing goods from being unlawfully opened, switched or stolen in transit is a key anti-counterfeiting tool for safeguarding goods in international logistics, especially for high-value goods, dangerous goods or transportation scenarios requiring full-time supervision.

Product Features

1. High strength anti-theft: metal material tensile strength up to 500-2000N, anti-cutting, anti-impact, can not be undamaged after locking dismantling, damage that is left marks;

2.Strong resistance to natural weathering: high quality steel material can withstand -40 °C ~ 120 °C temperature, salt spray, acid and alkali corrosion, suitable for shipping, outdoor and other harsh environments;

3. Easy operation: No professional tools are required, the seal can be completed by manually tightening the screw, and when dismantling, hydraulic tongs or special tools need to be cut.

4. Traceability: The surface is engraved with a unique code, bar code or corporate LOGO, which is convenient for scanning code tracking or batch management in logistics links;

5. Cost advantage: Compared with electronic seals, the cost is lower, it is suitable for large-scale batch use, and maintenance is simple.

Specifications and materials

· Material: Mainly steel (rust resistant and corrosion resistant), carbon steel (zinc / chrome on the surface to prevent rust);

· Length: Common 60-80mm, can be customized for different container lock hole spacing;

· Diameter: screw diameter 5-8mm, coarse diameter model suitable for high safety requirements;

· Color: the default is yellow, can be customized spray red, blue, yellow and other warning colors, or according to the enterprise VI color.

Quality inspection priorities

· Grip test: simulate external pull to ensure that the seal keeps cracking and does not loose under the rated pull;

· Corrosion-resistant test: Salt atmosphere test (such as 96-hour test) to verify durability in seashore and humid environment;

· Identification clarity: coding, LOGO and other identification need to wear, long-term use can still be clearly identified.

Examples of application scenarios

· Maritime containers: compulsory sealing of goods under customs control in international cargo;

· Cross-border logistics vans: containers for cross-regional transport such as China-Hong Kong Transport and the Eurasia Land Bridge are protected against theft;

· Storage of valuables: the door of the warehouse is sealed when the jewelry, electronics, pharmaceuticals, etc. are stored;

· Transportation of dangerous goods: tamper prevention and control in the transportation of chemical raw materials, gas tanks, etc.

After sales and custom services

· A 1-2 year warranty is provided, and non-human quality issues can be returned or exchanged;

· Supports mass custom unique coding, enterprise logo or anti-counterfeit marking, and some manufacturers can provide sample pre-confirmation services
