These metal cable seals are certified for both domestic and international maritime and land transportation, as well as various high-security sealing applications. Their uses span from shipping containers, general cargo trucks, courier cargo, airfreight, to the oil and gas industry, and virtually any application requiring a high level of closure and security.

Metal security seals can be customized to meet user needs, with typical laser engraving featuring logos, serial numbering, and barcodes. Laser engraving ensures that the markings on the seal’s metal body cannot be intentionally removed or altered under any conditions, as seen in ALDLOCK DUO’s design.
