When buying a garden shed there are a few things you need to do before you even start shopping for one… things like measuring the available space, deciding on colour and doors and setting a budget. However, one of the most essential things you need to check, which is commonly overlooked… is what wind rating the area you live in has been assigned.
What is a ‘Wind Rating’?
It’s a rating, which is assigned by your council to a certain area based on the geographic region, shielding, topography and terrain. Some areas in the country or even your state will experience different levels of winds- some only a small breeze and others cyclones.
Why do I Need to Check My Areas Wind Rating?
See the photo? Thats yours answer.
Garden sheds can become very dangerous buildings during a windy storm or a cyclone. Even more so than your home at times.
Due to their lightweight, foundation, structure and material, if they are not built specifically endure the wind levels in your area then they can be a danger to you. These buildings can be ripped apart in storms if the wrong one has been installed and the pieces can cause damage to its surroundings and even cause death. So it is vital you do your research and purchase the correct shed for your area so you can avoid any of the above.
Australia and New Zealand both unique in their weather because they can experience a vast amount of different climatic conditions in many different parts of the country on the same day. There are states and or local areas which experience high temperatures or seasonal flooding, some which experience snow and others heavy rain. But what concerns us most in the Shed industry are those areas that experience high winds or cyclones.
By checking the rating of your area and buying a shed which is designed and engineered to withstand heavy winds, you are not only ensuring the lifetime of your shed but also protecting yourself, family and others in your area.
How Do I Find Out My Areas ‘Wind Rating’?
The wind rating of your area is determined by your
- Geographic region
- Terrain conditions
You cannot make an estimate yourself based on past weather events in your area. It is recommended you check with your local council for the legally assigned rating to be safe.
This information that your local council will have, you can easily obtain by giving them a call. You will just need to give them your address to get the info (the address of the property you are planning to build the shed on).
Cheap Sheds Wind Calculator
Cheap Sheds has also created a Wind Calculator for you to use so you can get a good idea of what your area has been classified as.
How it Works:
STEP 1: Select your state
STEP 2: Select your region according to the map
STEP 3: Select your terrain/ living area conditions. Hover over each image for a description.
STEP 4: Choose the option which best describes the topography of your area. Hover over each image for a description.
STEP 5: Then choose the option which best describes the shielding/ how exposed your home is. Hover over each image for a description.
STEP 6: You will then be shown your Calculated Wind Rating for the area:
You can use this information to begin your research for your ideal Garden Shed and make an informed decision.
How Does it Help Me Choose a Shed?
Wind rating is classified with “N” or “C”. N stands for “normal” or “non – cyclonic” while C stands for “cyclonic”. This issue gets a little more complicated as some manufacturers still use the old “W” wind rating classification. Absco sheds, for example, use the “W” rating and our customers ask us often how it compares to the N and C ratings.
We have prepared a rough comparison table below for illustration purposes, to give you an idea on how the W rating compares to the C and N wind rating. I hope that you’ll find it useful. We also displayed the Pa rating and the maximum wind speed that a certain classification can withstand to demonstrate it further.

TOP RANGE IN THE MARKET
We have recently added a new shed to our range called the StormSHED by Durabuilt. It is at the moment the toughest Shed on the market specifically engineered for high winds.
The StormSHEDs are suitable for cyclone regions (Region D/Category 2) withstanding wind speeds up to 88 m/s (316 kph), compiling with W60 cyclonic conditions.
