Clean COLORBOND ® Ultra steel is BlueScope premium pre-painted metallic coated product designed specifically for roofing and walling in severe coastal & industrial environments found throughout Ghana.

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

        – G550 – Guaranteed Minimum Yield of 550 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 industry-leading metallic coating 55Al-Zn alloy coating, to provide enhanced corrosion resistance.

3. A thin pre-treatment layer is applied to optimize the adhesion of further coatings.

4. A corrosion inhibitive primer is oven-baked onto the surface.

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 a heavy downpour as compared to a product without “clean coating”

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 reference, the Solar Reflectance Index (SRI) value for African White is 86

* Depending on the level of insulation, colour, building shape and function.

  • 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.
