COLORBOND® steel is developed for, and therefore more resilient to, the severe sunlight and temperatures typical of Australian environments. BlueScope scientists have tested COLORBOND® steel in some of Australia’s harshest climates. 

Rest assured that COLORBOND® steel is guaranteed to meet relevant Australian standards. Make sure you look for the brand as not all painted steel is genuine COLORBOND® steel.



Recommended Fastening Method

When fixing into timber battens, we recommend a 12 gauge x 65mm Type 17 Hex Head screw. If fixing into steel purlins, please use a 12 gauge x 55mm Steel Fix Hex Head screw. When using the sheets as wall cladding, a 12 gauge x 25mm Type 17 Hex Head should be used for timber battens and for steel purlins, a 10 gauge x 16mm Steel Fix Hex Head screw is best.



Trimdek, in particular, pertains to square-fluted steel cladding that is available in long lengths. This means that one sheet can be used from ridge to gutter without having any end laps. Trimdek is remarkably strong (it can easily recover from deformation), it has excellent spanning capacity, it is lightweight, and it is properly rigid. And of course, it is available in a wide variety of colours that Colorbond roofing steel is well known for — earthy colours that reflect Australia's distinct landscapes.

Keep in mind that your house needs as much care and attention as its other features do. By choosing the best materials, like Trimdek roofing, your home can truly show your neighbourhood what a stunning mix of beauty and function truly looks like.
