How Metal Buildings Respond To Mother Nature’s Outbursts

There seems to be a common misunderstanding about the ability of metal structures to stand up to the forces of nature and a misconception that they are more susceptible to weather conditions than other types of buildings. This could not be further from the truth – as long as the building is of course installed correctly by professionals to industry standards.

The materials we use here at Southside Group are highly engineered to endure the punishment of the Australian weather. Additionally, there is increased safety in the repetition of a construction process – in our case that’s over 25 years of improving the safety of each structure.


During an earthquake, rather than a structure being slammed into with great force, the foundation itself is moved. Because the foundations are experiencing the force, having a building made from lighter components is a significant benefit as there is less force threatening to tear the building apart. Further, a great advantage of steel is that it allows for much more bend and flex before it will break than other materials. While concrete may crumble, and pull apart you’ll find that steel has a much better chance of surviving an earthquake.

Strong Winds

Strong storm winds are a significant risk to structures – and while tornados may not be common here down under, there are plenty of gale force winds that buildings must withstand. A great advantage of metal buildings is that they are completely ductile and while winds may make them bend and flex, they won’t break. Metal structures will be rated for how much force from winds it can survive and common ratings will be between 190 km/h, capable of surviving a category 3 cyclone, and 274 km/h capable of surviving even a category 5 cyclone. Detached metal buildings such as garages and barns can be sealed by closed doors to withstand even greater wind force.


Cyclones bring a dangerous combination of both high wind speeds and a lot of water. This is a lethal mix for structures as flooding is sure to occur which can cause its own damage in addition to the winds. Steel however, when galvanised, is almost unaffected by water and can easily survive flood events and, as already mentioned, is robust against strong wind speeds thanks to its ductility. Should a tree or some debris be knocked into a metal building, it may dent but will not crumble or shatter like most of the materials in a residential home will.


Bush fires are a major threat to structures – they spread rapidly and at times unpredictably. While a wooden structure will go up in flames or a vinyl building will melt, steel will stand strong as it is very resistant to fire. Fires and risk to personal harm can also be caused by lightning strikes. However, steel will not catch fire, and will protect the goods or people inside by transferring the shock from the strike safely to the ground.

Emergency shelters are often made from metal, and for good reason. Metal buildings are incredibly durable against many harsh conditions that would leave buildings of other materials crumbling. While we can’t change the conditions nature throws at us, we can be prepared for those conditions. For a carport that won’t buckle or break in the harsh Australian climate, look no further than Southside Group.
