Structural integrity and material composition

The primary difference between these two products lies in their durability and construction materials. A plastic security seal can often be easily broken by hand or with basic tools making it unsuitable for protecting containers against determined intruders. Conversely a bolt seal from ST Seal Group is constructed from heavy duty steel and high strength plastic coating to provide maximum resistance against physical cutting attacks. By utilizing industrial grade materials we ensure that our bolt seal hardware can withstand the extreme environmental stresses and physical manipulation that are common in long haul shipping operations.

Mechanical strength and tamper evidence

When security is the goal you must look for the mechanical benchmarks that define a high security device. An ordinary plastic seal provides only minimal visual deterrence while a bolt seal provides tangible evidence of tampering through its specialized locking mechanism. ST Seal Group designs every bolt seal with an advanced internal locking structure that requires professional bolt cutters to remove. This mechanical barrier ensures that any unauthorized attempt to open your container will be instantly obvious to customs and port officials. For high value shipments selecting the correct bolt seal is the most effective way to guarantee the safety of your goods.
