Metal Strip Security Seals

Metal strip security seals (also known as metal trailer seals) are used to secure trailer doors, rail wagons and containers, offering a tougher alternative to plastic ring seals. Manufactured from steel, they provide increased resistance to tampering while remaining simple and cost-effective for logistics applications.

With typical pull strengths between 40–70 KgF, metal strip seals offer practical mid-level trailer security between plastic indicative seals and higher security metal cable seals or bolt seals. Their narrow strip profile also makes them suitable for use with TIR cables on curtain-sided vehicles. Globe metal strip security seals are used in customs applications & have SSTA certification as an accepted HMRC Group 3 seal, where specified.

Frequently Asked Questions

 

What are metal strip seals?

Metal strip seals are strong metal trailer seals used to secure trailer doors, rail wagons and freight equipment. Manufactured from steel, they provide a stronger alternative to plastic ring seals while remaining simple and cost-effective for transport applications.

What are the benefits of metal strip security seals?

Metal strip seals offer higher strength and tamper resistance than plastic indicative seals, while remaining simple and cost-effective for high-volume transport use. They provide clear tamper evidence and are typically supplied with unique serial numbering for basic traceability and control.

When should I choose a metal strip seal vs a plastic ring seal?

Choose a metal strip seal when you need a more robust seal for transport or freight handling — for example, where plastic ring seals can be broken too easily or don’t provide sufficient deterrence. Plastic trailer seals are ideal for quick, low-cost sealing; metal trailer seals are the next step up for tougher applications.

Do I need ISO 17712 for trailer or container sealing?

ISO 17712 high security seals (such as bolt seals and certified high security cable seals) are typically specified for customs-controlled or international container movements. For domestic transport and general freight security, metal strip seals can provide an effective mid-level solution where ISO 17712 high security is not required.

How are metal strip seals applied and removed?

Metal strip seals are applied by looping the steel strip through the closure point, then inserting the strip end into the locking chamber until it clicks into place. Once engaged, the strip is held securely and any removal or interference will leave visible evidence. Metal strip seals are typically removed using snips or cutters.
