Wind Rating Calculator


Sheds Online has developed a unique Wind Rating Calculator that will provide you with a guide to the wind classification for your area.

Australia is made up of many varied climatic conditions and due to these variations it is essential that special Categories for sheds be assigned for specific Regions and site locations. The Australian Standards Association has introduced a basic breakdown of Regions in relation to wind velocity and topographic features (See Wind-Rating Map) SHEDS ONLINE have designed and certified all buildings in accordance with these guidelines and the Building Code of Australia, and have classified the buildings under the following Wind Rating Categories.

Non Cyclonic – N2, N3, N4 & N5
Cyclonic – C1, C2 & C3

Use this calculator to estimate what Category you may need. Simply select your state to begin.

The Wind Rating Calculator is only available on desktop.
