The metal is plated in zinc and coated in hard, durable and high visibility plastic. To further enhance security the seal number is laser marked on both the pin and bush.
The Tamper Evident barrier seal (often known as a 'Bolt Seal') aims to help reduce theft and stop unauthorised access by offering a high level of security. Any attempt of illegal entry will be clearly visible. This barrier seal is used predominantly in applications such as shipping, rail and road freight on Trucks, Trailers, Tankers and Cargo Containers.
