In exposed suburbs and cyclone-prone regions, the garage opening is often the weakest point in the façade. Australia and New Zealand use AS/NZS 4505 to set requirements for the design, construction and installation of garage doors and other large access doors—so the door and its fixings can resist wind actions and transfer loads safely to the building. standards.org.auPDF Standards Club
Engineering guidance also highlights that residential roller and sectional doors should be selected and installed to the wind category of the site, referencing AS/NZS 4505 to verify wind strength and performance. In cyclone regions, additional reinforcement and proper fixing are critical. James Cook University
How to tell if you need a wind-rated door
- You’re in a coastal/cyclone region or an exposed site with little shielding.
- Your builder/engineer has specified a wind classification for the dwelling.
- You’ve previously experienced panel deformation or track pull-out during storms.
What to ask your installer (AGG Doors checklist)
- Compliance: Which AS/NZS 4505 performance level is this door tested to? Request documentation. standards.org.au
- Fixings & Tracks: Are tracks, brackets, and fixings sized for my wind classification—not just the door curtain? James Cook University
- Maintenance Plan: Wind loads stress hardware; schedule inspections before storm season.
- Insurance: Confirm your policy requires a compliant door in your region.
Bottom line: A door that’s “fine” inland may fail at the coast. If you’re unsure of your site’s classification, we can coordinate with your builder/engineer and supply an AS/NZS 4505-compliant solution.
CTA: Protect the biggest opening in your home. Ask AGG Doors for a wind-rating assessment and quote.
