Frequently Asked Questions (FAQs)

1: What is the thickness of this 0.42mm BMT Colorbond corrugated roof?

The 0.42 mm is the Base Metal Thickness (BMT), which is the thickness of the steel before coatings are applied. Offering a great combination of strength, durability, and value, this is a typical and robust thickness for domestic roofing. It has been made to resist severe Australian weather conditions.

2: Does this corrugated roofing meet Australian standards for bushfire regions (BAL ratings)?

Yes, our Colorbond corrugated roofing satisfies Australian Standard AS 3959 for construction in bushfire-prone zones and is tested against it. The substrate and installation technique can affect the particular BAL score. For projects in high-risk bushfire zones, we advise speaking with your architect or builder to make sure the chosen product and installation meet the requirements for your Bushfire Attack Level (BAL).

3: Do I need expert help or special tools to install corrugated roofing?

While experienced DIYers can install corrugated roofing, we strongly advise using a certified roofing contractor. Making sure your roof is watertight, structurally sound, and keeps its warranty depends on correct installation. Professionals have the right tools, safety equipment, and expertise to fit corrugated roofing materials properly, especially on complex roof designs.

4: What are the delivery options and costs?

We offer reliable delivery across Australia. Delivery costs depend on your order size and geographic location. Adding your item to the cart and entering your postcode at checkout will give you a precise delivery quote. For your convenience, we deliver to building sites and residential addresses.

5: How does Colorbond steel compare with conventional Zincalume or galvanised iron for roofing?

Colorbond steel is a premium product that offers major benefits. While conventional galvanised or Zincalume steel provides strong corrosion resistance, Colorbond adds a patented metallic coating (Zincalume base) and a long-lasting baked-on paint surface. Available in a broad range of modern colours, it offers strong protection against chipping, peeling, and fading from the Australian sun. For modern homes, it provides a more complete, permanent solution.

6: Is it only for roofing, or can I use it for sheds, carports, and fences?

Yes, absolutely! Beyond basic roofing, this adaptable corrugated profile is a great choice for many other uses. It is often used for garage linings, sheds, carports, patios, farm fencing, and industrial fencing. Many people choose it for these projects because of its strength and traditional appearance.
