Shedding in Australia: Building a Cyclone-Rated Shed

Shed interior

Shed interiorCyclones are a real problem in Australia. Powerful cyclones have made landfall numerous times in the country leaving a path of destruction in their paths. For this reason, the government has provided guidelines for cyclone-proofing structures in certain regions to minimise the damage when a cyclone hits.

These measures include sheds, which can damage other structures if they are not cyclone-rated. Here are three things you have to consider in building cyclone-rated sheds.

Structural Design

You will need to consult with a qualified engineer about the structural design of the shed you are planning to build. They need to meet the engineering standards for cyclone-rated sheds. Particularly, your purlins, rafters, and haunch brackets should be sturdy. They should also be narrowly spaced with a 10% overlap to improve the integrity of the shed.

You should also get their opinion about the materials that you will use. Galvanised metal is probably a good choice instead of wood because it does not corrode as easily. The main concern is how well your shed will stand up against extreme winds.

Compliance with BCA requirements

The Building Code of Australia (BCA) is responsible for Low, High, Low (LHS) testing of buildings in regions where cyclones tend to frequent. They have a set of requirements designed to check if your building will remain intact in case of a cyclone.

It can seem a lot of trouble to make sure that you are building a cyclone-rated shed, and it can be expensive. It may be more practical to buy a cyclone-rated shed from a reputable company instead. They can also cost a lot, but you will avoid the hassle of going through the process of building your own. Moreover, you can be sure that your shed would still be there after the storm has passed.
