Manufacturing Quality Standards

Trellicor (Pty) Ltd is ISO (International Standards Organisation) compliant. Trellidor is ISO 9001:2015 certified in terms of QMS requirements, audited and assessed by the London-based Loss Prevention Certification Board.


BRE-LPCB Approved to loss prevention standard 1175

Physical security barriers are a vital component in protecting the occupants of any building, be it residential or commercial. These barriers must be able to withstand and deter potential threats effectively. The only way to ensure that security barriers are dependable is through independent testing and certification.

Independent certification bodies, such as the BRE Global Loss Prevention Certification Board (LPCB), play a crucial role in setting standards for security products. The LPCB is a third-party certification body that rigorously tests security products to ensure they work effectively and deliver on their promises.

The certification process involves testing the security products to the limits, including against various types of attack, such as manual attacks, tool attacks, and blast attacks. Only those products that pass the rigorous tests are awarded a Certificate of Product Approval. These approved products are then listed in the Redbook of approved product suppliers, which is used by specifiers worldwide.

Trellidor, a leading manufacturer of physical security barriers, has several designs that have achieved certification from the LPCB. These products have been designed and tested to meet the needs of high-security risk locations, such as transport hubs, embassy staff homes, kiosks, retail chain stores, and shopping centres.
