FAQs

Which fasteners do I use for corrugated iron sheets?

We recommend class 4 screws due to their durability and longevity. For standard roofing application to timber or metal purlins, check out our range of Multifix screws to make the job easier.

How many fasteners do I need per sheet?

The most common practice is three fasteners for internal spans and five fasteners for single and end spans. Do not fix fasteners on the overlap because the underlapped sheet would leak.

What is the maximum recommended spacing of supports for normal conditions (mm)?

Roofs: end spans 1300, internal spans 1700, unstiffened eaves overhang 250, stiffened eaves overhang 350. Walls: end spans 2700, interior spans 2700.

Purchase COLORBOND® Roofing and wall cladding in Corrugated Iron Sheet Profile

Please note this is the .48 BMT thickness sheet.  Please see other listings if you require t standard .42 BMT sheet.

It is among the world’s most popular metal roofing products due to its high quality and versatility. These corrugated iron roofing panels, also known as Custom Orb, are suitable for traditional and contemporary roofing projects alike.

General Info

COLORBOND® roof and cladding sheets are available in various colours to match absolutely any building project and are 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, ensuring easy fixing by the conventional method. To provide maximum weather protection, our Corrugated has a 1.5 rib overlap. The wide cover (762mm) allows for quick installation, saving on materials and labour. This versatile profile can be used on a minimum roof pitch of 5 degrees.

Fixings
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 are a choice between 12 gauge x 25 mm timber fix screws when fixing into the timber. Otherwise, ten gauge x 16mm will do the trick when fixing steel. These screws are shorter as they are fixed into the corrugation's pan (or valley). "Cover of roofing sheet": is the measured amount each sheet will cover (including the side lap) when laid in position on the roof. IE, the cover of a corrugated roof sheet is 760mm or .76 metres. 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 by 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 unplanned maintenance).

Buying the Right Roofing for Your House

 

It is essential to have a sturdy roof on top of our heads, especially when blazing hot or raining heavily outside. Colorbond metal roofing is an excellent option for many Australian homes as it is weather resistant and comes in a wide range of colours to suit the style of your home. Corrugated iron roofing is another popular choice, which you can purchase from us.


When choosing between Colorbond metal roofing and corrugated iron roofing, it is essential to consider the pros and cons of each option. Colorbond metal roofing is an excellent choice if you are looking for a robust and weather-resistant roof that will last for many years. Corrugated iron roofing is also a good option as it is tough and durable and can be painted in any COLORBOND colour you like.


Things to Consider in Choosing the Right Roofing for You


When choosing between Colorbond metal roofing and corrugated iron roofing, one thing to consider is the cost. Colorbond metal roofing is more expensive than corrugated iron roofing, but it is also more durable. If you are looking for a budget-friendly option, corrugated iron roofing is good.


Another thing you should consider is the climate in your area. Corrugated iron roofing is a good choice for hot climates, as it helps to keep the home cool. Colorbond metal roofing is a good choice for areas that experience a lot of rain or storms, as it is weather resistant.
