This is a high-performance, pre-painted steel developed by BlueScope, comprising multilayers of coatings and offering high levels of corrosion resistance, excellence in colour performance and resistance to tropical staining.

Research and development
• Continue to develop and improve product performance via BlueScope Research (BSR ) and collaboration with others research institutional / universities.
• At any given time BlueScope has 18000 samples on outdoor exposure sites all over the world, which are then brought back on an annual basis for assessment.
• Provide technical support / literature (see website for data sheets, fact files, corrosion bullitens etc.

Product certification and traceability
• Assurance of our commitment to quality by SIRIM and SABS product certification scheme.
• Contain branding text at reverse side for product identification and traceability.

Warranty – We offer a product/material warranty on a project to project basis.

Preferred by many roll forming operators – Due to the consistent tensile strength/thickness and superior paint coating.

Thermatech™ (Designed by BlueScope) – 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 example, the SRI value for colour Off White is 85

Clean Technology (Designed by BlueScope) – Thermal comfort is maintained by the dirt resistance properties in Clean COLORBOND ® steel. The solar reflectance of the roof sheeting 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.

ZINCALUME® base – The coating on ZIN CALUME ® steel comprises 55% aluminum, 43.5% zinc and 1.5% silicon. It has excellent corrosion performance, which out performs Galvanized Z275 material by up to 4 times in the same en vironment.

Super Polyester Paint System and Superior Primer Technology (Designed by BlueScope) – Proven paint durability performance against natural weathering (color fading / chalking / flaking / dirt staining).
