What Is Clean COLORBOND® ULTRA Steel?
Clean COLORBOND ® Ultra steel is
Product Attributes
Guaranteed Minimum coating Mass AZ200 (200g/m2) – 100g/m² on the top and bottom
Steel Grades – G300 – Guaranteed Minimum Yield of 300 MPa

Clean COLORBOND ®Ultra steel is only manufactured by BlueScope Steel
Clean COLORBOND® Ultra steel has superior corrosion resistance paint performance properties making it one of the most cost-effective building materials for harsh industrial and severe coastal environments.
Clean COLORBOND® Ultra Steel contains 5 LAYERS OF PROTECTION
Manufactured in Vietnam to Australian Standards (AS1397 and AS/NZS 2728) and tested in some of the harshest Australian /Asian conditions over the last 50 years, genuine Clean COLORBOND ® steel is far more than just ‘paint on steel’.
1. The steel base is manufactured to meet relevant Australian Standards, ensuring strict adherence to the required grade and strength.
2. The base is then coated in BlueScope’s
3. A thin pretreatment layer is applied to optimize the adhesion of further coatings.
4. A corrosion inhibitive primer is
5. A topcoat of specially developed, exterior grade paint is oven baked on to provide resistance to chipping, flaking and blistering and to ensure the finish retains its look for longer.
Clean Technology – Dirt Resistance and Improved Thermal Performance
- Thermal comfort is maintained by dirt resistance property in Clean COLORBOND® steel.
- The reflectivity of the roofing sheet will be influenced by the amount of dirt staining.
- Therefore, retaining a clean appearance is very important for maximizing the cooling effect of roofing sheets.
- The dirt particles on Clean COLORBOND® steel can be easily washed away during
heavy downpour as compared toproduct without “clean coating”
The dirt particle on Clean COLORBOND® steel can be easily washed away during

Point 5. Clean COLORBOND ® steel contains Thermatech ® Technology
WHAT is THERMATECH® SOLAR REFLECTANCE TECHNOLOGY?
Thermatech® solar reflectance technology is incorporated in Clean COLORBOND® steel to lower surface temperature by absorbing less heat from the sun. In other words, Thermatech® is able to reflect the solar heat off roofing material.
- Thermatech® Solar Reflectance Technology – reduces roof surface temperature by up to 6°C*
- Reduce annual cooling energy consumption by up to 15%*
For ease of
* Depending on
- Thermatech® technology optimizes the thermal performance of every colour without changing their appearance. The roof
therefore consumes less energy for air-conditioning and helps to mitigate the Urban Heat Island (UHI) effect.
