Australian Wind Ratings for Steel Sheds

Wind Rating For Your Steel Shed

If you’re looking to put up a shed a number of factors are likely to be considered. A wind score is one aspect you might not have thought about. Continue reading to learn what a wind score is, how it affects your choice of shed, and why it matters.

What is Wind Rating?

The explanation is simple: certain areas are given a wind score by the council. The score itself is calculated on a number of factors, including climate, topography, shielding, and terrain. Wind ratings help councils decide how high the winds in a particular area are likely to be, which then helps them assess that buildings are safe to be built in that area.

Why Are Wind Ratings Important?

Sheds can become very dangerous in high winds or in a cyclone. They can injure people, damage property, or even cause death if the wind lifts them up. The weather can shred them, and pieces can cause horrific damage. It is critical for homeowners to ensure that there is no possible projectile in their backyard or property. When building a shed, making sure it is rated high enough for your area is very important, particularly in the case of extreme weather events.

What is The Wind Rating In My Area?

See Map Below for Regions

Asking your local council is the best way to determine the wind rating of your area. Because there are so many different factors to consider, it’s not something that can be one answer for one zone.

Nevertheless, in all areas controlled by the council, the local council has calculated the wind score. They will be able to share their wind rating with you by providing them your address. This data can then be used to ensure that your shed has the correct wind rating for your property.

In Region A, winds are fairly mild and pick up a bit when you move into Region B which is more coastal, and you can expect a max of around 147KM/hr at worse. Most of our Australian made sheds are suitable for Regions A and B.

Region C is where you experience high damaging winds of which garden sheds are only suitable if you add a cyclone upgrade kit. Not all garden sheds models offer this option, but the upgrade kits ensure your shed has extra steel framing and fixings that are compliant for high winds. If you are installing a garden shed in this cyclonic region then you will require a cyclonic upgrade kit that comes with appropriate ‘certificate of compliance’ engineering for local council building approval.

Region D is the extreme weather zones. You are best to speak to one of our experts who can make recommendations for building in these areas.

Please note: Superior Garages DO NOT construct garden sheds. We specialise in larger shed builds only, for residential, industrial and commercial purposes.

Will My Shed Be Safe?

Excellent quality sheds should come with a wind rating. As long as the rating meets or exceeds the standards in your area, and the shed is constructed professionally, it should stand against the weather in your area.

If you’re having trouble finding the right shed for your needs, consider the option of getting a custom shed built. While standard sheds are clearly built at standard heights and depths, customised sheds will have your specified factors integrated into the structure, such as roof pitch and openings, all of which help your shed withstand heavy winds.

Custom sheds can be built from more durable materials like Colorbond or Zincalume. Both of these products feature genuine Bluescope steel sheeting and have a 15-year warranty. We ensure that every shed designed or created by Superior Garages & Industrials will stand the test of time.

What’s Involved In Designing A Shed?

If you are considering building a custom shed and you are looking for your own design to meet wind rating standards or for other reasons, contact one of our team at Superior Garages & Industrials.

To get you exactly what you need, we can add a number of customisable options. We work with each client to develop a project that fits both you and local council’s criteria. Contact us today.

Custom Designed Steel Sheds

SGI has successfully delivered a wide variety of residential projects, working closely with owner-builders, builders, and architects who realise the benefits of using prefabricated building systems to suit specialised shed designs.

Building a Steel Shed Has Many Benefits…

  • Strength
  • Design freedom for your shed project
  • Building your shed is fast, efficient, and resourceful
  • Space creation
  • Aesthetically pleasing and functional
  • Endlessly recyclable


Factory fabrication enables specific tolerances, increased speed of construction, and reduced waste. Additionally, Work Place Health & Safety risk is reduced whilst weather and other variables have less of an impact on the overall shed building process.

Looking for A Custom-Designed Shed on the Sunshine Coast?

SGI has been building steel sheds, commercial and industrial buildings, garages, and carports on the Sunshine Coast for more than 30 years. We are proud of the fact that a large percentage of our new projects are referred to us by our previous clients, or are previous clients returning for a new product.

We stand by the fact that to produce a quality building of any shape or size, quality is essential in 3 main areas…

  • Structural design and integrity (specialised in-house engineering)
  • Quality of all building materials (genuine Australian steel and Colorbond)
  • Construction workmanship (professional builders and contractors)


Our in-house shed design and engineering services allow for creative, functional, and cost effective solutions. For more info, contact our team today.
