Trimdek vs Corrugated — Which Roof Suits Your Home?
When building or re-roofing in Australia, one of the first decisions you’ll make is choosing between Trimdek and Corrugated COLORBOND® roofing. Both profiles are manufactured from genuine BlueScope® Steel and offer exceptional performance — but the design, application, and finish can make one option better suited to your home than the other.
What’s the Difference Between Trimdek and Corrugated Roofing?
Trimdek is a high-strength, modern roof sheeting profile with wide ribs and deep flutes — perfect for long spans and contemporary designs. Corrugated roofing, on the other hand, features traditional curved waves, offering timeless appeal and flexibility across residential and heritage builds.
| Feature | Trimdek | Corrugated |
|---|---|---|
| Profile Shape | Wide ribs and deep channels | Classic curved pattern |
| Roof Pitch | As low as 2° | Minimum 5° |
| Aesthetic | Sleek, modern look | Traditional, versatile |
| Applications | Industrial, commercial, modern homes | Homes, sheds, patios, renovations |
Why Choose Trimdek Roofing?
Trimdek sheeting is ideal for modern designs where sleek lines and minimal joins are a priority. With its bold rib structure and ability to span longer distances, it’s a favourite for contemporary homes, carports, and commercial projects. Trimdek also performs exceptionally well in areas with high rainfall, as the deeper channels provide fast water runoff.
Available in all COLORBOND® colours, including the Matt range, Trimdek roofing delivers strength, durability, and a distinctly architectural look.

Why Choose Corrugated Roofing?
Corrugated roofing — also known as Custom Orb — remains Australia’s most popular roof profile. Its timeless wave design complements every home style, from coastal cottages to modern builds. Corrugated roofing is lightweight, cost-effective, and easy to install. It’s also incredibly versatile for walls, awnings, and sheds.
Made from genuine BlueScope® .42 or .48 BMT COLORBOND® steel, corrugated sheets offer excellent strength and corrosion resistance, backed by BlueScope’s warranty for peace of mind.

Which Roof Is Right for You?
The right choice depends on your home’s design, pitch, and budget. If you’re building a sleek, contemporary home or shed that needs low-pitch capability, Trimdek is the better fit. For a more classic or traditional look with proven versatility, Corrugated COLORBOND® roofing is the top choice.
Both profiles are made from genuine BlueScope® steel, ensuring long-lasting performance and colour retention under Australia’s harsh conditions. Regardless of which profile you choose, you can count on Australian-made quality, nationwide delivery, and decades of trusted performance.
Installation & Accessories
To complete your roofing system, ensure you use matching roofing screws, flashings, and sealants. Both Trimdek and Corrugated sheets can be finished with ridge capping, barge flashings, and gutter systems to create a fully sealed, weatherproof result.

FAQ – Common Questions
Is Trimdek more expensive than Corrugated?
Generally, yes — Trimdek’s thicker profile and higher spanning capability make it slightly more expensive, but the modern appearance and performance often outweigh the difference.
Can I mix Trimdek and Corrugated on the same project?
Yes, some builders use Trimdek on low-pitch roof areas and Corrugated for walls or awnings to achieve both strength and design contrast.
Which profile handles rain better?
Trimdek has deeper flutes, making it ideal for areas with heavy rainfall or low roof pitches, while Corrugated offers excellent drainage at standard roof slopes.
