Potential wind speeds are an important factor to consider when designing a dome shelter.
Australia is divided into four wind regions based on the different types of windstorms that are typical to that area. A structure with Wind Region Rating has been engineered to withstand the wind loads of that areas as set out under the Australian Standards AS/NZS 1170:2:2002.
- Wind Region A
- Includes the southern coastline and inland Australia and has an Ultimate Design Wind speed of up to 147.6km per hour.
- Wind Region B
- Includes the northern coastal areas of Australia that are not prone to cyclones and has an Ultimate Design Wind speed of up to 186.84km per hour.
- Wind Region C
- Includes the Tropical Cyclone prone regions of northern coastal Australia and has an Ultimate Design Wind speed of up to 232.2km per hour.
- Wind Region D
- Is the only part of Australia that has a Severe Tropical Cyclone prone areas and has an Ultimate Design Wind speed of up to 316.8km per hour.
Our team will ask where your shelter is to be located to ensure that the Shelter is built to withstand that region’s wind rating. All our shelters are designed to withstand the strongest winds for each region so you can reassured that your shelter won’t be damaged by the winds in your local area.
