Bolt seals



Security seals are mechanisms utilized to seal shipping containers in a way that provides tamper evidence and many level of security. Such seals will help detect theft or contamination, either accidental or deliberate. Security seals are usually employed to secure truck trailers, vessel containers, chemical drums, airline duty-free trolleys and utility meters. Typically they may be considered an affordable strategy for providing tamper proof of intrusion into sensitive spaces.

Security seals is often split into two main groups: single use and reusable. Single use seals are normally manufactured from plastic or metal, plus the used material and production technology is the key to their security level. Reusable seals tend to be electronic or mechanical as opposed to just made from plastic, in case purely plastic, just one single part is reusable. Electronic and mechanical seals are typically employed for the transportation industry, with seal fixed to the rear of trucks, trailers and shipping containers. A reusable mechanical or electronic seal could be fitted on the rear or loading doors, extending a cable from itself through fixing points for the doors, then when sealed generating a unique number that is logged. Once the door is next opened this number changes, so that it provides tamper evidence for your load.

Certain requirements for specific security degree of seals are defined in the ISO 17712. The seals that fit in with our prime security level and Security level may also be called "barrier seals". They are constructed with different metals or metal alloys, meaning that they demand special tools to become opened, such as bolt cutters or pliers. Cable seals and customized seals also belong to this category. Intended to deter opportunistic theft of high value goods, additionally they can be branded and numbered to further improve tamper resistance and still provide excellent security for containers. The seals which can be from the Indicative level concerning ISO 17712 are created from plastic or thin metal.

Bolt seals are employed to secure shipping containers, trucks and trailers. A bolt seal useful for securing containers must comply with the ISO 17712 high security seal to become accepted by customs worldwide in ocean shipping. The C-TPAT[3] (Customs Trade Partnership Against Terrorism) specifies ISO 17712 compliant security seals for use. Bolt seals are usually closed manually (by pushing the seal body and head together) and opened if you use bolt cutters. This provides a strong and secure seal for transportation, while remaining convenient for staff in ports and warehouses.

All ISO 17712 compliant seals are numbered on both seal body and head, to counteract substitution of either part. This is usually done using laser marking, which cannot be rubbed off.

Ball seals are commonly utilized for securing trucks. They include a metal strip by using a punched hole, attached to a housing section. As soon as the strip is bent and threaded through the hole, a ball into the housing section locks it set up. Most ball type seals belong and then the indicative level about ISO 17712.
