Cyclonic Sheds


Is Your Shed Cyclone Ready?

  20 April 2018

The most important thing to look for when engaging a local shed supplier is their regional knowledge, industry know-how and experience with engineering steel buildings specifically for cyclonic areas. 

If you are in the northern parts of Queensland, Western Australia or the Northern Territory, you’ll be aware of the potential dangers to your property and assets during cyclone season (November – April). Having a steel building on your property that isn’t ShedSafe® accredited or engineered for your site can result in the loss or damage of your assets, property or even injury. Building a steel building that is ShedSafe® accredited is your best protection against property damage when storms occur.

If not engineered to withstand the weather conditions of your property location, a steel building can become hazardous when brutal weather such as a tropical cyclone hits. Other extreme weather conditions such as additional pressure from fluctuating wind loads can result in fatigue to building materials.

The Building Council of Australia [BCA] lists the below three requirements for cyclonic regions to ensure sustainability against the extremes of weather:

  • Wind lock roller doors
  • Screws specific for cyclonic regions
  • Differences in the overlap of purlins and girts

It’s important when choosing a supplier to build your steel shed that you ensure these requirements are not only offered but are a fixed inclusion in your quote and subsequent purchase if the site is located within a possible cyclonic region.

In addition to the BCA requirements, you should also ensure that your chosen supplier offers further build inclusions in their quote to comply with ShedSafe® standards and ensure a resilient and robust shed is supplied. Some of the additional build inclusions your supplier should offer are;

  • Site specific engineering that is designed to the conditions of your site
  • Fully bolted frames
  • Z-purlins and girts with decreased spacing and using cleats
  • Purlins and girts with a minimum overlap of 10% of the bay width
  • Metal roofing systems that have undergone standardised low-high-low cycle tests
  • 0.47 TCT (Total Coat Thickness) sheeting for roof and walls
  • Class 4 roof screws plus cyclonic washers
  • Building designs to +0.7 CPI (Internal Pressure Coefficient)
  • Roller doors with certified wind lock kits

Every Sheds n Homes store is operated by local shed experts that are well-versed in their knowledge of the region, are up to date with all things steel and have a wealth of experience in designing and engineering steel buildings for cyclonic and non-cyclonic areas.

Your steel shed should not only protect your assets and property when faced with potentially damaging weather but also be built to last by knowledgeable, local experts that can advise you on the requirements and regulations for your local area.
