Metal seals security seals are certified for domestic and international shipping and other applications that require a high degree of closure and protection. Usability: shipping containers, truck general cargo, courier freight forwarder, airway cargo, oil & gas industry related. There are several basic designs of the metal security seals: bolt seals, ball seals, and cable 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 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 security seals allow for more versatile application, as they have variable length of the locking mechanism limited only by the cable length. Typical applications for cable seals include sealing trucks and railway cars transporting valuable commodities. An internal locking mechanism prevents the cable from being retracted. Most cable seals are classified as security or high security level as to ISO 17712.
