What is Corrugated Corten Steel?
Corrugated corten steel refers to corten sheets shaped in a wavy or corrugated pattern. This pattern provides additional structural strength, making it ideal for both roofing and siding applications.
Corten steel develops a protective rust-like patina when exposed to weather, which prevents further corrosion and enhances durability.
Applications include:
- Roofing
- Siding and cladding
- Architectural and landscaping projects
- Industrial and agricultural buildings
Corrugated corten steel combines rust-resistant properties with visual appeal, making it suitable for both exterior and interior designs.
GNEE Corten Advantages
Our gnee corten steel corrugated panel offer the benefits of corten steel without the downsides of natural rusting:
- Arrives pre-weathered, no need to wait for rust formation.
- No rust runoff or staining.
- Comes with a standard paint warranty, unlike raw corten steel.
- Suitable for exterior or interior applications.
- Reduces pre-treatment time and costs compared to traditional corten steel.
Recommendation: Request a 7/8" corrugated sample panel to see the authentic finish up close.

Is corten steel cladding expensive?
Because of its high-strength, low-alloy composition and added durability, Corten Steel Cladding typically costs more upfront than mild steel or standard cladding materials. Prices can range from $600 to $1,200 per tonne, depending on material thickness, finishes, and supplier
What is a corten panel?
Corten Steel (sometimes known as weathered steel) is a group of steel alloys that are often used in outdoor construction. Corten Steel was designed to eliminate the need for painting and if left outside, exposed to the elements, they will develop a rusted appearance in just a few months.
What is the lifespan of corten steel?
Corten Steel thicknesses of modest specification [2.0mm or 3.0mm] are perfectly fit-for-purpose for + 25 years longevity, in most environments / applications. For + 40 years longevity, an additional 1.0mm thickness should be added, to mitigate the forecast material loss.
How thick are Corten panels?
The Corten is available in thicknesses from 22 gauge up to ½" thick in a variety of lengths and widths, which makes it compatible with any type of project.
Do magnets stick to corten steel?
Other than austenitic stainless steels, most steel does attract magnets. Galvanised steel, Corten steel, mild steel, cold-reduced steel and hot-rolled steel are all magnetic.
Can you seal Corten steel?
Everbrite Coating is a popular choice for sealing and protecting Corten steel to protect the rusted patina. It also prevents rust drips and staining problems by sealing in the rust patina, protecting the surrounding areas and people who may brush against the rust.
