Windstrong® Windlocked Roller Doors

In May 2013 the National Construction Code was changed to include reference to AS/NZS 4505:2012 Garage doors and other large access doors (up to 3m high) with specific focus on new construction in Regions C and D.

The relevant wind pressure for doors higher than 3m can still be computed by referring to AS/NZS 1170.2 or AS 4055.
