Application

The typical applications for this range include locations at risk of targeted attacks against high‑profile individuals such as politicians, celebrities, or other high‑risk persons.

Suitable Applications for an Attack‑Rated Door

  • Escape routes for panic rooms
  • High‑end residential properties
  • Museums
  • Art galleries
  • Schools
  • Supermarkets
  • Valuable stock rooms
  • Doctors’ offices
  • MP residential or workspace locations
  • High‑net‑worth offices
  • Security facilities

Many commercial and leisure facilities may also consider this option for more affluent premises or areas at high risk of terror‑related attacks involving blunt or bladed weapons, such as high‑street retail properties.

Description

Attackdor is a steel security doorset with an attack rating, not a security rating. It complies with the new LPS 1673 security standard developed by the Loss Prevention Certification Board, aimed at protecting against violent forced entry attacks by individuals targeting people and valuable assets.

Security Doors for High Net-Worth Personnel

With global tensions increasing, threats toward high‑profile and high‑net‑worth individuals are becoming more frequent. This shift has created a growing need for personal protection solutions such as anti-intruder doors. Strongdor's attack-rated doorset provides a critical physical barrier between those at heightened risk and individuals attempting to cause harm, helping to delay and disrupt targeted attacks from bladed weapons.

Security Doors for High Value Items

Smash‑and‑grab theft, rioting, and opportunistic attacks remain common methods used to access valuable goods. Doorsets certified to LPS 1673 help counter these threats by creating a dependable delay, giving security teams or emergency responders time to act.

These doors are well‑suited to environments such as:

  • Jewellery stores
  • Museums
  • Art galleries
  • High‑value retail spaces

While no door can guarantee complete prevention, Strongdor's bespoke security steel door with attack rating provides proven resistance that significantly slows forced‑entry attempts.

Steel Doors for Protection

Whether the threat involves large‑scale public attacks or targeted incidents, steel doors for commercial properties with attack‑rated performance can play a vital role in safeguarding occupants. With even a 30‑second certified delay, this door tested to LPS 1673 creates essential time and distance between an attacker and potential victims, supporting safer escape, controlled lockdown procedures, or timely security intervention.
