The metal seals group includes disposable self-locking metal seals.
They can be conventionally classified as bolt type power seals, cable type power seals and indicatory type power seals.
The power seals take a lot of efforts to be destroyed. Thus they are strongly reliable locking devices with a high protection level. They are designed for sealing warehouses, containers, etc. When using the bolt type seals the sealed object needs to have matching openings, while when using the cable type seals the sealing openings may not match and may be situated at a significant distance from each other.
The indicatory type seals are simple, handy and cheap devices that successfully substitute the old lead seals. They are used with inexpensive cargo; postal parcels and transportation vehicles; warehouse premises and other sites.
All the seals are marked with unique identification numbers and other marks. The sealing is done manually without using any tools, while the unsealing of most of the models requires the use of tools.
