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 sheets 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.
Walling Sheet spans - please consider wind pressure only.

How to Order Corrugated Colorbond Sheets Online


Reasons Why You Should Choose Corrugated Iron for Your Homes

Corrugated iron is a fixture in Australian homes, having a rich history dating back to the 1830s. It has continuously improved since its early beginnings while retaining its properties, which made it the number one choice for roofing in most homes and structures.

Though there are other options in the market that can provide your roofing needs, here are a few reasons why you should choose corrugated roofing:


Unique Appeal. Corrugated iron, because of its simplistic design, gives a different feel and texture to houses. The ribs, which sit on top of structures like waves, can definitely add to a boring edifice. Its thinness also contributes nicely to architects trying to add detail to a roof because it can easily be cut and made into different lengths and sizes.


Lightweight but sturdy. Since they are rolled into thin sheets, these materials can easily be transported and stacked prior to installation. Although many argue that there is little strength offered by Colorbond® corrugated roofing, iron, being its intrinsic component, suggests otherwise. This characteristic of the metal is very important to those working on a budget because you don’t need to spend too much on materials to support the roof.


Longevity. Improved coating has enabled corrugated iron to last much longer than its predecessors. Rusting, which is the main knock in corrugated roofs, is no longer a problem as most coats are specifically designed to repel water. New inventions even reflect heat from the Sun and, therefore, prevent sudden expansion and stress to the material.


Weather-resistant. Apart from aesthetics, corrugated roofings are functional and serve a purpose. The ribs work as pathways to drain rainwater or thawing ice, which have settled on the roof. Recent technology has also reinvented corrugated iron into fire-, wind-, and hail-resistant metal roofing, and a new kind of heat-reflecting coating helps in keeping temperatures in check.

Easy to install. Corrugated roofing is relatively convenient to put up. Its ribbed design, light weight, and thin structure all contribute to this characteristic. The ribbings make it easier to put the ends of two sheets together with the help of screws and washers, while its thinness makes it easy to cut. The light weight, on the other hand, takes away the need for other equipment as manual labour can do most of the job.


Corrugated roofings are expected to last long with minimal maintenance work required. A periodic check here and there should be done to look for faded coating, scratches that can grow into cracks, or possible holes where water can seep and leak into — these are probably the only causes for concern.


COLORBOND Roofing Questions — What to Ask Your Roofing Supplies Store

Installing a roof, as simple as it sounds, is actually a technical task, which requires skill and expertise. When building a new house or scheduling repair or replacement, you most likely will need to ask some questions to get the job done.


If you are not familiar with every aspect of the installation, it is understandable for you to have a few questions for your roof sheet supplier. Roofing materials have different characteristics and may have specific handling methods and techniques, so it is wise to have a couple of enquiries at the ready when you contact them.


Even though most of the answers to your questions may be available online, it is still best to ask your suppliers about them because they certainly have first-hand knowledge. We employ qualified roof plumbers, who are the experts in their field and are familiar with most available materials.


There are also a limitless number of choices and combinations to choose from and they will certainly help you decide. Most recommend COLORBOND roofing, among the leading roofing materials in the market. They have different designs and colors that may suit your location or the general feel that your house wants to project.


However, COLORBOND still has a number of options from which you can choose from. To help you out with the right COLORBOND roof for you including profiles such as corrugated iron, here are some questions to ask your supplier:

What roofing is best for this weather or climate? Different materials have different strengths. Some are more specific to a certain climate and extreme weather events. Some are flexible, in that they can handle most stresses. Leaks can be bothersome during rainy season; high winds can test the strength of your roof; hail and sleet can also be damaging. Knowing your climate will determine which roof is best.


How long will this roof last? You want the utmost protection for your house and the most cost-efficient option so you won’t worry about future costs. COLORBOND corrugated iron is known for its durability and is therefore built to last. Asking your supplier which is best for you would prove to be wise in the long run.


How often does it need maintenance? Roofs can give you major headaches, especially during the rainy or winter seasons. You don’t want to do some maintenance or sudden repairs in the middle of the rainy season. You want an engineered roofing material that has been tested to withstand every outside hazard imaginable.


Why Home Builders Prefer To Use COLORBOND Sheets

Building (or even just renovating) a home can be a very expensive project. The cost of materials can really set finances back, and then there’s the costly process of securing permits and completing other paperwork, plus the manual labour that people have to set part of their budget aside for. Most folks are fully prepared financially for the expenses of this undertaking — which is good, but it’s crucial that they make sure that the final outcome will prove to be worth all the money. One way of doing that is by being exceptionally particular with the quality of materials to be used for home construction.

For top quality roofing materials, people can never go wrong with COLORBOND sheets – professional home builders prefer them and recommend them. Despite being honed by advanced technology, they are some of the most budget-friendly roofing products in the market these days. In addition to this, performance-wise, they rival and even outwork more expensive roofing sheets.

Home builders also mention that COLORBOND sheets offer versatile function; they are very easy to install for different aspects of the home construction, not just roofing. They even recommend these sheets, especially the corrugated roofing iron sheets, as material for roofs and wall cladding, or even for backyard fences, gates, and partitions for outdoor living spaces.

Design-wise, this brand of roofing products outperforms other brands for being available in a vast selection of attractive colours to specifically meet the aesthetic requirements of home owners. From dark sophisticated hues, to charming pastels, to warm neutral tones, to classic favourites, clients easily find the specific shade or combination of colours to complete the scheme they have in mind for their home’s exterior.

But these colours are not only for aesthetic purposes; the colour treatment for COLORBOND sheets also functions as additional protection for the material and insulation feature (it can help maintain the ideal climate inside the house). As mentioned earlier, advanced technology was used to develop the brand’s roofing products, so even the paint or colour treatment has multiple functionalities.

And finally, when it comes to providing homeowners the best value for their money, these roofing products come with impressive warranties so homeowners get the peace of mind that should something unfortunate befall their roof, they can get a replacement or have it repaired by the experts for free. However, they can trust that there’s a very, very slim possibility of that happening because COLORBOND roofing sheets are weather-resistant, corrosion-resistant, termite-resistant, and have superior durability.

With these amazing building products, home builders earn the satisfaction of their clients for they are able to deliver top quality results.
