What is Metal Seal

Metal Security Seals are used to mechanically secure a variety of heavy duty applications. These types of metal security seals are significantly stronger than most plastic pull-tight seals and are frequently referred to as “Barrier Seals” as they are designed to provide a “barrier” for entry.

A metal strip seal is a robust and secure sealing mechanism widely used for various applications that require tamper-proof protection.

 

It consists of a metal strip, typically made of high-quality stainless steel, designed to enclose and secure valuable items such as containers, cargo, or utility meters. The strip is threaded through a closure mechanism, forming a loop that can only be tightened or loosened using specialized tools. Once tightened, the metal strip seal creates a strong and unyielding bond, effectively preventing unauthorized access or tampering. It offers excellent resistance to tampering, thanks to its durable construction and unique design, making it highly suitable for transportation and logistics industries, as well as ensuring the integrity of sensitive equipment. With its reliable security features, the metal strip seal provides peace of mind and ensures the protection of valuable assets throughout their journey or storage.

 

Definition of Metal Strip Seal: Tamper evident security seals (like Metal Indicative Seals) are metal security seals used to seal cargo or valuables when in transit and provide some level of security. But rather than providing a strong barrier to prevent entry or theft, these seals are designed in such a way as to show obvious visual evidence of any attempt to tamper with or gain entry to the goods.
