For a range of heavy duty applications, metal security seals are utilised to mechanically fasten. These metal security seals are much more durable than the majority of plastic pull-tight seals and are sometimes referred to as "Barrier Seals" since they are intended to act as a "barrier." They offer security features as well as the capacity to show signs of tampering. Shipping containers, vehicles and trailers, valves, and drums are just a few examples of typical places where metal seals are used.
