Colorbond roofing is a popular material today for those who want a roof that is durable and strong. It has been made to suit Australian conditions which, as we all know, can be extremely hot or extremely cold – sometimes on the same day. It is this constant temperature variation that can cause a roof to degrade, as it expands and contracts so often. Compared to some other countries where the temperature stays very cold or quite warm for months at a time, Australian temperatures go up and down very often.
That is why when a product is made for our conditions you know that it is going to remain strong and durable for at least as long as the warranty, but most likely a lot longer as well. But how exactly has Colorbond roofing been made so that it is strong enough to withstand such temperature variations without degrading?
The base material used is Zincalume steel. This product has an alloy coating of aluminium, magnesium and zinc which gives it a strong coating that resists corrosion. A conversion layer is added to the surface of this steel to improve adhesive properties and then a polymer primer is baked onto it. In the final step, a top coat of exterior grade paint that has been specially developed for the project is applied to the steel sheeting and also baked on. This ensures that there is a high resistance to peeling, chipping and cracking. The super Polyester coating technology that is used for the product ensures that it looks new for much longer.
The important technologies that make the steel strong and keep the colour looking new, have been developed by BlueScope Steel, the makers of Colorbond, over several decades. However, when you go to purchase the product you cannot buy it directly from BlueScope. They make the product, but they don’t actually sell it. Instead, you have to find a supplier in your district that sells it. That is not usually difficult to do as many building suppliers have the product, or can get it for you.
However, you need to make sure that it is the original product and not a look-alike that you are buying. Only then will you be sure that you are getting a top quality product that has the warranties BlueScope Steel offer – a product that complies with all relevant Australian standards. There are several different warranties for the different products available, so you need to go to the website to find out all the details.
While Colorbond roofing is constantly increasing in popularity, it is also possible to use the product for cladding, feature walls, fences, garden sheds and farm sheds and barns because it is so versatile. There are many different surface configurations from simple corrugations to more complex designs.
