Corrugated Iron COLORBOND® is renowned throughout the world as the product of choice for roofing and cladding applications. Its corrugated iron profile creates an iconic look for both traditional and contemporary projects.

COLORBOND® is enormously popular thanks to its:

  • Versatility—use it on roofs or walls – you’re only limited by your imagination.
  • Strength—.42 or .48 BMT hi-tensile steel offers an enormous strength to weight ratio making the sheets easier to handle, less costly to install, and, with a life expectancy of at least 50 years, one of the longest lasting products on the market.
  • Wide profile—sheet width of 762mm means fewer sheets required and faster installation time adding up to lower cost.
  • Weatherproof qualities—1.5 rib overlap ensures a snug weatherproof barrier and protects your home. Colorbond is also rated for high winds and is pest resistant.
  • Visual appeal—a wide range of colours means you can choose to make a visual statement with your cladding or blend into the environment—your choice.

Using LYSAGHT CUSTOM ORB® as Roof Sheeting

You'll Save Money When You Purchase a COLORBOND® Roof

Generally, you get what you pay for and going cheap can cost you dearly in the long run but COLORBOND® is a top quality product with amazing features that come with a reasonable price tag.

And with a life expectancy of at least 50 years, superior weather proof, fire resistance and pest resistance qualities you are getting real value for money.

You can save even more money when you:

  • Choose a reputable COLORBOND® expert supplier- No1 Roofing & Building Supplies is the largest wholesale suppliers of metal roofing products in Sydney. We provide competitive pricing and our free expert advice is worth its weight in gold. We can also cut sheets to your specifications.
  • Take accurate measurements for the number of sheets required—this limits expensive wastage or being caught short and requiring extra deliveries (involving additional charges and inconvenience).
  • Pick up your order instead of paying for delivery charges. However, you may find the time and hassle of doing it yourself is outweighed by the convenience of a professional delivery team especially if you have a large order.​

Bulk orders give commercial customers the opportunity to make even greater savings thanks to special large quantity discounts.

No1 Roofing & Building Supplies also offer value added services such as sheet metal fabrication and our renowned friendly advice and service. We’ve been dealing with roofs for many years and we can save you both time and money.

Technical Recommendations

Class 4 screws are the recommended choice for fixing COLORBOND® sheets.

For walling applications screws are fixed through the pan, the lowest point of the corrugation allowing for a shorter length screw. For fixing to timber 12 gauge 25mm timber screws are suitable and for steel you will need 10 gauge 16mm screws.

The choice of .42 or .48 thickness sheets will depend on wind resistance loads, batten spacing, and foot traffic. Standards AS1562.1-1992, AS4040.1-1992 and AS4040.2-1992 limit the maximum support spacings to the following:

Installation Tips

Fascia boards form an important part of your COLORBOND® roofing system helping to seal the roof against weather and pest damage.

Fascia boards also provide a smart finished appearance but it’s essential that you install them correctly.

Measure accurately to avoid expensive wastage. Don’t forget you’ll also need to allow some extra length for the mitred ends.

Your COLORBOND® roof and fascia boards form an important part of your home or commercial premises so it’s vital that you get the best advice.
