Wind Rated Garage Doors

In high wind and cyclonic areas, it’s sometimes necessary to engineer your garage or industrial door a little differently to ensure it withstands the particular stresses it may be subject to. Steel-Line cyclone garage doors are ideal for use in homes, sheds, commercial and industrial warehouses in high wind prone areas.

The National Construction Code (NCC) 2013 – Housing Provisions (Building Code of Australia Volume 2) includes a reference for garage and large access doors for Region C and Region D to comply with AS/NZS 4505 – 2012 ” garage doors and other large access doors”. This came into effect on 1st May 2013.

Steel-Line Garage Doors has re-engineered our wind rated garage doors and had them tested at the James Cook University against the wind loading requirements as laid out in the updated AS/NZS 4505-2012.

Postless Cyclone Sectional Garage Doors

The design features include heavy duty struts, commercial style side hinges, top brackets and a unique stile reinforcement that sandwiches together the various components of the garage door, so that it provides maximum resistance to forces exerted by cyclonic and high winds.

The garage door is connected to the jamb via high strength galvanised track, which combined with the garage door provides protection from cyclonic winds without the need for any form of additional bracing that must be fitted after receiving a cyclone warning.  It dramatically reduces the potential for the garage door to sustain damage in blow in / out, cyclonic and high storm wind environment.

Wind Brace Sectional Garage Doors

The Steel-Line Wind Brace system incorporates the use of removable steel wind brace post(s) that is installed to the garage door once a cyclone warning is received. It takes about 2-5 minutes to install, and no tools are required.

The door construction incorporates a number of significantly enhanced items, which still ensures a smooth door operation. However when used in combination with the removable wind brace posts, it enables your sectional garage door to withstand high force wind conditions and dramatically reduces the potential for the garage door to sustain damage and blow in, or blow out, event.

Windlock Roller Doors

The patented Steel-Line Windlock system incorporates a moulded lug secured to the door curtain, which interlocks the matching shaped side-track. The design ensures smooth operation and minimises air infiltration enabling your roller door to withstand high force wind conditions and dramatically reducing the potential for the door to sustain damage and blow in.

Our patented Windlock system also serves as an extra safe-guard against break-ins because the curtain cannot be easily pushed in helping to prevent unwanted entry.
