General Info

COLORBOND® roof and cladding sheets are available in a wide array of different colours to match absolutely any building project and is made in Australia using BlueScope steel. 

Corrugated COLORBOND® is one of the most durable, long-lasting roofing materials available and it’s virtually maintenance-free. Made from hi-tensile steel this profile whilst strong, is also lightweight which minimises sheet damage.

Corrugated sheeting is pierce fixed which ensures easy fixing by the conventional method. To ensure maximum weather protection our Corrugated has a 1.5 rib overlap. The wide cover (762mm) allows for quick installation, saving on both materials and labour. This versatile profile can be used on a minimum roof pitch of 5 degrees.

Here at Metal Roofing Online, we only use and recommend Class 4 screws when installing your roof sheeting as they last considerably longer in the elements. In a standard roofing application, when fixing to either timber or metal purlins, we have in our range a Multifix screw which is the perfect choice for this roofing iron.

When using the corrugated iron sheet in a wall cladding application, there is choice between 12 gauge x 25 mm timber fix screws, when fixing into timber. Othewise, 10 gauge x 16mm will do the trick when fixing into steel.These screws are shorter as they are fixed into the pan (or valley) of the corrugation. "Cover of roofing sheet" : is the measured amount each sheet will cover (including side lap) when layed in position on the roof. IE the cover of a corrugated roof sheet is 760mm or .76 metre. Please consider both resistance to wind pressure and foot traffic for roofing spans. 


Please consider a couple of factors when deciding whether you need .42bmt or .48bmt sheets as roof covering:

Your batten spacing
How often the roof will be walked upon

The maximum recommended support spacings are based on testing in accordance with AS1562.1-1992, AS4040.1-1992 and AS4040.2-1992.


Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance).


Maximum Support Spacings (mm)

5 Ways to Prolong the Life of Your Corrugated Iron Roof


Roofs are not easily visible to the homeowners' eyes from where they stand, so it can take some time before they notice that the metal sheets require repair or replacement. Since roofs take a significant beating from the elements day in and day out, they can be expected to exhibit wear and tear after several months or years. It's important to subject the roof to regular inspections and maintenance measures to ensure that it is kept in good condition, and that your home stays well-protected. Here are some valuable care and maintenance tips that you can follow to prolong the life of your corrugated iron roof: Perform regular cleaning. This is perhaps the simplest way you can extend the life of metal roofing sheets. Perform routine cleaning so you can remove branches, leaves, stones, twigs, bird droppings, old nails and pieces of timber; leaving them lying on the roof leads to the creation of crevices and accelerated loss of coating in the areas between the debris and the roof. Keep the roof secure. Loose fixings may be further loosened by hard wind and rain. Make sure all sheets are screwed down. Replacing damaged sheets. If a roofing sheet is beyond saving with simple maintenance procedures, a replacement will be necessary. You need to consider factors like colour, materials, sheet length, profile, fastenings, and the availability and compatibility of materials to ensure that the replacement sheet is functional as well as a good match to the appearance of the original roof. You can consult your local roofing specialists about how well top brands like Colorbond and Zincalume sheets will work with your original roof and design scheme. Colorbond sheets, for example, are a good match if they will be used to replace an unpainted zinc roof (Zincalume may be too glossy to be a good match, and is not compatible with traditional lead flashings as corrosion will ensue when the two materials are combined). On the other hand, if you will be replacing everything (roofing sheets, gutters and downpipes), it's a good idea to use COLORBOND® for all of these roofing features for excellent performance.
