Gnee Corten is a classic corrugated Corten steel roofing and wall cladding solution designed for projects that demand visual character, durability, and cost efficiency.
Its combination of deep corrugation geometry, natural weathering performance, and simplified installation requirements makes it a preferred choice among builders, architects, designers, cladders, and roofing professionals.
With no substrate requirements and a bare steel finish that naturally oxidises over time, Heritage Corten delivers both heritage charm and contemporary appeal in a single, low-maintenance system.
Design & Aesthetic Characteristics
The defining feature of Heritage Corten is its deep, wavy corrugated profile, which creates a strong architectural rhythm and a bold shadow effect across façades and roof planes.
Installed using stainless steel fasteners as exposed fixings, the system becomes an intentional design element rather than a hidden detail.
Over time, the steel develops a rich, naturally oxidised patina, resulting in warm earth tones and textured surfaces that continue to evolve with exposure to the elements. This natural aging process ensures that every project achieves a unique visual identity.
Material & Performance Advantages
Heritage Corten is manufactured from 0.7 mm thick Corten weathering steel, offering excellent strength and corrosion resistance while remaining lightweight and easy to handle on site.
Unlike coated or painted systems, Heritage Corten is supplied as a bare base metal, eliminating the need for:
- Painting
- Recoating
- Ongoing surface maintenance
Once installed, the material protects itself through the formation of a stable oxide layer, significantly reducing long-term maintenance costs.
Installation & Cost Efficiency
One of the key advantages of Heritage Corten is its installation efficiency:
- No plywood substrate required, reducing material and labour costs
- Quick and straightforward installation, ideal for tight project schedules
- 700 mm effective sheet coverage, allowing large areas to be covered rapidly
- Cut-to-length sheets, minimising waste and on-site cutting
Matching trims and flashings are available to ensure a consistent finish and professional detailing across roofing and wall cladding applications.
Products Applications
Heritage Corten is suitable for a wide range of roofing and wall cladding applications, including:
- Residential homes (heritage-style and contemporary designs)
- Commercial buildings and architectural façades
- Industrial and rural structures
- Feature walls and statement roofs
Its versatility makes it equally effective in projects seeking to blend into natural surroundings or to stand out through bold material contrast.

Q1: What are Corrugated Corten Roof Panels?
A:
Corrugated Corten Roof Panels are weathering steel (Corten steel) panels with a corrugated profile designed for roofing applications. They offer a unique rust-like appearance, high durability, and excellent resistance to atmospheric corrosion, making them ideal for both industrial and architectural projects.
Q2: What material is used for these panels?
A:
The panels are made from Corten steel (A606, SPA-H, or equivalent grades), which forms a stable rust layer over time. This protective layer prevents further corrosion, eliminating the need for painting or frequent maintenance.
Q3: What are the typical applications of Corrugated Corten Roof Panels?
A:
Residential and commercial roofing
Industrial and warehouse buildings
Agricultural structures, such as barns and sheds
Pergolas, carports, and outdoor shelters
Architectural projects where aesthetic weathered appearance is desired
Q4: What are the standard sizes and thicknesses available?
A:
Thickness: 0.8 mm – 1.5 mm (customizable)
Panel width: 750 mm – 1000 mm (effective cover)
Length: up to 12 m (custom lengths available)
Corrugated profiles are designed to provide structural strength and facilitate water drainage.
Q5: What are the advantages of using Corten steel for roofing?
A:
Durable and weather-resistant: Forms a protective rust layer naturally
Low maintenance: No painting required
Aesthetic appeal: Unique warm, rusted look that evolves over time
Eco-friendly: 100% recyclable material
Long lifespan: Typically 30–50 years in most environments
Q6: Can Corrugated Corten Roof Panels be cut and installed on-site?
A:
Yes. Panels can be cut, drilled, and fastened
