Steel thickness - .42 BMT

Sheet cover - 762mm

COLORBOND® Corrugated Iron Roof Sheets are among the world’s most popular metal roofing materials due to its high quality and versatility. These corrugated iron roofing panels, which are also known as Custom Orb, are suitable for traditional and contemporary roofing projects alike. The Colorbond corrugated iron is made in Australia using Bluescope steel.

Colorbond roofing materials are available in a wide array of different colours to match absolutely any building project. Moreover, the Sheeting 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 iron 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 fixing roofing 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.

Please consider a couple of factors when deciding whether you need .42bmt or .48bmt sheets as roof covering: (if you would like a price on .48bmt product, please ask us)

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).

Getting the Most Out of Colorbond Roofing

Colorbond roofing remains the top choice for both property owners and their roofing contractors. And it’s not so surprising, considering the roofing material's reputation and the benefits it offers.

However, there are some customers who complain about the performance of their roof after installation. A great deal of these complaints can be attributed to a poor installation process. Here are a few key points that will help you get the most out of your roofing and prevent unnecessary problems.

Transit and storage

The roofing material should be kept dry during its transport and storage. Otherwise, moisture can wreak havoc on the metal roofing sheets, especially when these are stacked closely in bundles.

The roofing sheets should be placed above ground, and when these get wet, these should be wiped immediately and allowed to dry.

Use the right fastener

Using the wrong fastener can facilitate premature corrosion and shorten the metal roof's lifespan. Colorbond recommends the use of fasteners that conform to AS 3566.

Use neutral cure silicone sealants

Gutters and downpipes facilitate the flow of rainwater from the roof toward the downspout. But even if the two do a good job of drawing water away from the roof, the presence of joints and laps can lead to leaks. This is why it is crucial to properly seal joints and laps. And when you are sealing these, you need to use a neutral cure silicone sealant. The wrong type of sealant can cause corrosion.

Clean up after installation

After cutting or piercing metal roofs, a debris called swarf is produced. Leaving swarf on metal roofing can lead to the formation of rust stains which can make it look unsightly. 

Ideally, swarf should be cleaned off the roof after each work day. Also, if there is a need to cut or pierce the metal roof, this task is best performed on the ground using a cold cutting saw.

Install gutters and downpipes correctly

Improper installation of gutters and downpipes can lead to pooling or the formation of ponds of water on the roof. Eventually, when this problem is not rectified, plants can grow on the roof.

Use the right type of paint

If you notice surface blemishes or fine scratches on the metal roof, avoid the temptation of touching up the roof using the wrong type of paint. Otherwise, you will compromise the performance and appearance of the roof. You can simply leave these blemishes and scratches as is without having to worry about the performance of your roof.

Use the right cleaning materials

Cleaning the roof properly can help prolong its lifespan. Ideally, you should wash it with a solution of diluted kitchen detergent and water and use a broom with soft nylon bristles.

Working with Corrugated Iron – A Few Tips and Tricks

Apart from homeowners, designers and roofing contractors, plenty of DIY-ers count themselves as fans of corrugated iron.

And what's not to love about this roofing material? Apart from its versatility, it also lends a unique and rustic charm that makes it perfect for a wide variety of design styles, whether it is used as a roof or as a material for a DIY project.

In terms of strength to weight ratio, this building material is counted as one of the strongest, making it ideal for a wide variety of application s —not just roofing. That strength is complemented by its corrosion-resistance, making it ideal for long-term use.

If you are working on a project that entails the use of this roofing material, you will need a few tools to make your task easier. These tools include a measuring tape, an angle grinder with a thin wheel, and a drill with metal bits. 

Before you work with this roofing sheet, you will need to prepare it by laying it flat on either a large work table or on any flat surface. Ideally, you should have ample space to move around freely.

In measuring this roofing sheet, use the tape measure and a permanent marker to mark the areas that need to be trimmed. You may also use a ruler or a piece of wood that has a straight edge as a substitute for cutting a straight line.

After marking the areas that need to be trimmed, the next thing that you need to do is to set up the angle grinder. Make sure that it is mounted securely to prevent loose metal sheets from flying around. It is recommended that you use the grinder's fastest setting.

In using the grinder, start by applying gradual pressure on the spinning wheel instead of pushing the grinder with brute force. This may cause the tool to bounce.

Hold the grinder firmly and constantly check its wheel to see whether it is running straight or not. Avoid twisting the grinder which may cause its wheel to shatter. If the cutting wheel gets too small to cut through the sheets, change the cutting wheel that you are using.

Once you have trimmed the sheets, tilt the wheel of the grinder down and then drag it on the areas that have been recently cut. This removes the burrs.
