Meshlock Cyclonic Security Doors and Screens

Engineered for Extreme Environments & Wind Regions C and D

In Australia’s cyclonic regions, winds exceeding 159km/h can transform everyday objects into lethal airborne debris. Standard security screens are often insufficient against these high-velocity projectiles. The Meshlock Ultra range is among a select minority of products engineered, tested, certified and rated in these extreme conditions.

Certified Performance & Compliance

To meet Australian Standards for cyclonic regions, security products must undergo rigorous independent testing in a NATA-certified laboratory. The Meshlock Ultra range has been tested by Azuma Design Pty Ltd (AZT0480.21), confirming full compliance with AS/NZS 1170.2:2021 (Clause 2.5.8).

  • Wind Region Suitability: Certified for use in Wind Regions C and D.
  • Regulatory Compliance: Our Ultra range meets all requirements for the BCA, NCC, and Department of Housing regulations for Building Classes 1 through 9.
  • Verified Results: Official test results are available upon request for builders, architects, and homeowners.

The entire Meshlock Cyclonic range has undergone rigorous independent testing by Azuma Design and successfully exceeds the 44m/s debris impact requirement. These products are fully certified for use in Wind Region D—Australia’s most severe cyclonic zones. Full compliance certificates and test reports are available upon request.

The Meshlock Ultra Cyclonic Range

Our Ultra Frame provides the structural backbone required to withstand extreme pressure and impact.

  • Meshlock Ultra Hinged Doors: The ultimate barrier for entry points, combining the strength of the Ultra frame with our patented mesh-locking technology.
  • Meshlock Ultra Cyclonic Window Screens: Fixed screens designed with a specialized cyclonic build-out to protect glass from high-speed debris.
  • Meshlock Ultra Fire Escape Screens: Provides the dual benefit of cyclonic protection with the cyclonic build out and a rapid “one-touch” emergency exit.
  • Meshlock Ultra Cyclonic Sliding Doors: The next generation of cyclonic protection for large sliding glass openings. This range passed 3 Cyclonic tests at 44m/s making it the strongest on the market.
Key Features
  • Debris Impact Certification: Independently tested in NATA-accredited laboratories to pass the Cyclone Missile Impact Test. It is rated to resist the impact of a 4kg piece of hardwood timber travelling at high speeds, protecting the building’s glass and structural integrity. 
  • Tested for Regions C and D: Certified compliant with AS/NZS 1170.2:2021 (Clause 2.5.8). This ensures the screens can withstand the intense wind pressures and debris typical of severe and “extreme” cyclonic events (Wind Region D).
  • NATA-Accredited Performance (Azuma Design): Validated by Azuma Design Pty Ltd (Test AZT0480.21), providing homeowners and builders with verified, scientific proof of safety.
  • The National Construction Code (NCC) specifies that in Wind Regions C and D, any opening (windows/doors) must either be made of impact-resistant glass or be protected by a certified cyclonic-rated screen.
