Defence

Contact us

Defence environments operate under heightened risk, where security, resilience, and reliability are critical to mission success. Every opening must perform as part of a broader security strategy, protecting personnel, assets, and sensitive operations.

From controlled entry points and secure zones to exposed and hardened locations, defence openings are required to withstand extreme conditions while maintaining strict access control. Systems must perform under impact, pressure, and environmental stress, without compromising operational readiness or safety.

Our defence solutions are designed for the realities of high-risk environments:

  • High-performance opening systems engineered to support enhanced security and threat mitigation
  • Heavy-duty constructions designed to resist impact, forced entry, and harsh environmental conditions
  • Configurable solutions that adapt to project-specific security levels, operational requirements, and facility layouts

When mission-critical performance is essential, Lietzke delivers defence opening solutions built to withstand pressure - without compromise.
