What is a metal seal?

Metal seals are all made metallic security seals that are certified for domestic and international shipping and other applications that require a high degree of closure and protection.

Usability of metal seals: shipping containers, truck general cargo, courier freight forwarder, airway cargo, oil & gas industry related security applications.

There are several basic designs of the metal security seals: bolt seals, cable seals, and fixed closing tin seals.

Bolt Seals

Bolt seals security seals are used to secure shipping containers, trucks, and trailers.

A bolt seal used for securing containers must conform to the ISO 17712 high security seal security standard in order to be accepted by customs all around the world in ocean shipping.

Bolt seals are generally closed by hand (by pushing the seal body and head together) and opened with the use of bolt cutters.

This gives a strong and secure seal for transportation, while remaining convenient for staff in ports and warehouses.

Cable seals

Cable seals security seals allow for more versatile application, as they have variable length of the locking mechanism limited only by the metallic cable length.

Typical applications for cable seals include sealing trucks and railway cars transporting valuable commodities.

A strong internal metallic locking mechanism prevents the cable from being retracted.

Most cable seals are classified as security or high security level as to ISO 17712.

Fixed closing tin seals

Fixed closing tin seals are commonly used for securing trucks cargo along the route by seeing if it was tampering with. So from here is the name of metal truck seals.

Metal truck seals consist of a metal strip with an security mechanism attached on one side. Because of all metallic construction of this type of security seal and the fixed closing “click” style this kind of security seals are among the strongest security seals that seals industry can provide.

High Security Seals: all metallic made seals are accompanied by a higher level of security and an audit trail due to the possibility of laser marking or engraved a sequential number on them and the ability to have a company name or logo laser etched. An additional serial barcode can be laser printed where the size of the metal seal body can fit the printing.
