The Robust Shield: Colorbond Roofing Quintuple Layer of Defense

In the dynamic world of building materials, COLORBOND® steel stands out with its innovative approach to durability and protection. Specifically designed to withstand the harsh Australian climate, COLORBOND® roofing is more than just a piece of painted steel; it’s a multi-layered defense system that ensures longevity and aesthetic appeal. Let’s delve into the five layers that make COLORBOND® steel a superior choice for roofing.

1. Steel Base 

At the foundation lies the steel base, manufactured in accordance with stringent Australian Standards (AS1397 and AS/NZS 2728). This ensures that the steel not only meets the required grade and strength but also forms the robust backbone of the entire system.

2. Metallic Coating Incorporating Activate® Technology 

Next, the steel base is coated with BlueScope’s industry-leading metallic coating that includes Activate® technology. This layer significantly enhances corrosion resistance, a testament to the material’s ability to endure the elements.

3. Pretreatment Layer 

A thin pretreatment layer follows, which is crucial for optimizing the adhesion of subsequent coatings. This layer acts as a primer, ensuring that the protective layers firmly bond to the steel base.

4. Corrosion Inhibitive Primer 

The fourth layer is a corrosion inhibitive primer that is baked onto the surface. This primer plays a pivotal role in safeguarding the steel against corrosive forces, further enhancing the material’s resilience.

5. Exterior Grade Topcoat 

Finally, the exterior grade topcoat is applied and baked on. This isn’t just any paint; it’s specially developed to resist chipping, flaking, and blistering. The topcoat ensures that COLORBOND® steel retains its aesthetic quality for longer, maintaining the vibrancy and integrity of the color.

Together, these five layers form a composite barrier that protects against corrosion, extreme weather, and the wear and tear of time. COLORBOND® roofing’s layered approach is a reflection of BlueScope’s commitment to quality and innovation, ensuring that your roof is not only strong and beautiful but also enduring.


This article provides a concise overview of the technology behind COLORBOND® steel’s renowned durability. For homeowners and builders alike, understanding these layers is key to appreciating the value and reliability that COLORBOND® roofing brings to any construction project.
