What Trimdek is and where it works
Trimdek is a pierce-fixed (screw-down) profile with bold, evenly spaced trapezoidal ribs roughly 29mm high. The flat pans between the ribs give it a crisp, architectural appearance that reads as 'modern' rather than the traditional wavy corrugated look.
Because of its rib geometry, Trimdek can be laid to a low minimum roof pitch — making it a strong choice for skillion roofs, extensions, patios and carports as well as main house roofs. It's equally at home on residential re-roofs and light commercial buildings.
- Low minimum pitch — suits skillion and low-slope roofs
- Clean, modern square-rib appearance
- Strong spanning ability, fewer supports needed
- Excellent value for money among Colorbond profiles
Trimdek vs corrugated and Klip-Lok
Compared with classic corrugated (Custom Orb), Trimdek has a flatter, more contemporary face and a slightly lower minimum pitch. Compared with Klip-Lok, Trimdek is pierce-fixed (visible screws with sealing washers) rather than concealed-fix, which makes it more economical while still being weather-tight when installed correctly.
If you want the most modern, screw-free look or you have a very low-pitch roof, Klip-Lok may suit better. If you want a sharp modern profile at the best price, Trimdek is usually the answer.

Trimdek Colorbond Roofing FAQs
Is Trimdek good for a low-pitch roof?+
Yes — Trimdek's rib profile lets it be laid to a low minimum pitch, which is why it's so common on skillion roofs, extensions and patios. We'll confirm the right profile and pitch for your specific roof during the free inspection.
Are the screws visible on a Trimdek roof?+
Yes. Trimdek is pierce-fixed, so the fasteners (with sealing washers) sit on the ribs. Installed correctly they're neat and fully weather-tight. If you want a completely screw-free finish, Klip-Lok concealed-fix is the alternative.
