For best results, always install in accordance with the manufacturer’s guidelines, using fasteners specifically designed for steel supports. Both roofing and walling installations require three fasteners at internal supports to ensure a secure and long-lasting fit.

🧰 Maintenance and Repair Tips

To keep your COLORBOND® corrugated iron sheets looking their best and performing strongly, regular maintenance is key. Simple cleaning of the roof and wall cladding, especially after exposure to hail or strong winds, helps maintain the vibrant colour and prevents corrosion. Inspect your sheets periodically for any signs of wear or damage, and address repairs promptly using compatible materials to ensure a seamless finish.

Pay special attention to end laps and expansion joints, as these areas are critical for preventing water ingress and reducing the risk of corrosion over the long term. Properly sealed laps and joints help maintain the integrity of your roof and walling, ensuring your building remains protected. With routine maintenance and timely repairs, your COLORBOND® roofing and wall cladding will provide a cost effective, long-lasting solution that stands the test of time.
