Product Overview
Metal security seals are the ultimate structural barrier mechanisms used to secure international logistics, heavy transport and bulk industrial storage. They are called high security seals ( H-Class ) , built to withstand extreme physical force , organised theft , and give a clear visual indication of tampering over high value cargo shipments across continents .
Our metal security seals offer reliable, tamper-evident protection for shipping containers, trucks, pallets and warehouse storage. These seals are developed for logistics operators, freight forwarders and customs authorities, merging high-strength construction with adherence to international maritime and safety standards.

FAQ
Q: RFID seals cost a lot more than traditional seals. Are they worth the investment?
A: Yes, the long-term gains are enormous:
90% reduction in manual inventory time, reducing labour costs dramatically.
Reduced inventory shrinkage and protection against product substitution (especially for high value items).
Automated data capture that eliminates expensive customs delays and compliance penalties.
Security record is verifiable and tamper-evident. This means you could get lower insurance premiums.
Q2: Is it possible to read an RFID seal that has been violently damaged?
Q: Is it readable in the normal way? A: No. Physical tampering destroys the internal antenna and the tag responds with a specific error code (e.g. "0000"). This is flagged instantly by the system as "tampered" and is far more reliable than a normal visual inspection.
Q 3: Will metal containers block RFID signals?
A: Specialised anti-metal engineering provides the best performance. The back of the chip is made of wave-absorbing materials to protect the tag and reflect electromagnetic waves back to the reader, achieving an identification rate of over 99% on metal surfaces.
Q4: Is the seal reusable?
A: No way. These seals have a one-time locking mechanism which is irreversibly 'broken' when opened. Reusing them defeats the purpose of tamper-evidence and is illegal under international customs regulations.
