Bluescope Colorbond® is manufactured to exacting standards, combining Zincalume® steel with a continuous polyester paint coating for exceptional durability. Whether you’re planning a Metal Roof Installations Sydney project or a Sydney Roof Replacement, Colorbond® delivers unmatched performance, style and longevity.
Understanding Roof Profiles
Different profiles suit different applications. Whether you choose corrugated, Trimdek® or Custom-Orb®, each profile is engineered for strength and aesthetics. Purlins (the horizontal support beams beneath roofing sheets), battens (the secondary supports that secure the sheets) and substrates (the base layer that sits under the battens) must be configured correctly to ensure long-term performance.
Quantifying Long-Term Savings
Beyond its sleek appearance, Colorbond® roofing delivers measurable value. Owners report up to 20 % lower maintenance costs over ten years, thanks to reduced corrosion and minimal re-tightening of fixings.
Meeting Local Conditions
Sydney’s coastal salt-air and occasional hailstorms demand a robust system. Colorbond® roofs resist hail damage on the northern beaches and withstand inner-west industrial fallout, outperforming traditional materials across all districts.
Built for Design Flexibility
Colorbond® comes in over 22 colours and can be formed to suit complex roof shapes, from bold contemporary profiles to heritage styles, enabling seamless transitions across different roof geometries.
Fire Resistance and Ratings
Colorbond® roofing is non-combustible and tested under Australian Standard AS 1530.8.1 for fire performance. It achieves a BAL–29 rating—suitable for most bushfire-prone areas—and can be specified to BAL–40 for higher-risk zones, giving you extra protection and peace of mind.
Ensuring Safety and Standards
For your peace of mind, we use AS/NZS 1891-compliant harnesses and conduct site-specific checks on clearance and anchor points before work begins. This rigorous approach keeps installers safe and projects on schedule.
Selecting the Right Fasteners
Fasteners must match both sheet profile and substrate. We only use high-tensile, corrosion-resistant screws, ensuring your roof remains watertight and secure through Sydney’s varied weather.
Customer-Focused Installation
For your peace of mind in any Metal Roof Installations Sydney project, we clean gutters and downpipes, remove all debris and protect landscaping before installing new sheets. That level of care makes every installation seamless.
