However, Trimdek provides a more modern, streamlined profile that enhances the aesthetic appeal of any building. COLORBOND® steel is renowned for its strength, longevity, and extensive color palette, including shades like Classic Cream, Deep Ocean, Cottage Green, Woodland Grey, Shale Grey, Night Sky, Pale Eucalypt, Manor Red, and Evening Haze. This wide range of colors allows you to match your roof or wall cladding to your project’s design vision, ensuring both quality and style for your roofing needs.

Trimdek vs. Corrugated Roofing

A common question is how Trimdek compares to corrugated roofing; the answer lies in their profile and spanning capabilities.

Trimdek has a flatter profile and superior spanning ability compared to traditional corrugated sheets. It supports wider purlin spacing and allows for lower-pitched roof applications (2° minimum), whereas corrugated requires 5°. For a modern architectural look and increased efficiency, Trimdek is the smarter choice.
