For best results, confirm all measurements in millimetres before ordering to ensure accuracy across your project, and follow installation guidelines for COLORBOND® Trimdek roofing to achieve a durable finish.
All Trimdek roofing sheets, including ZINCALUME® Trimdek roof and wall sheets, are cut to your specified length, allowing for a tailored fit that aligns with your roof design. This reduces installation time, improves finish quality, and helps achieve straight, consistent roof lines from eave to ridge.
Ordering multiple lengths? Simply add each size as a separate line item to ensure your order is manufactured correctly and arrives ready for installation.
Our Trimdek sheets are made from genuine COLORBOND® steel, designed and manufactured by BlueScope for Australian conditions, and we also offer ZINCALUME® Trimdek roofing sheets (.48 BMT) for projects that prefer a metallic finish.
