Advantages of Corrugated Corten Steel Sheets
- Long-term corrosion resistance without painting
- Natural rust-patina finish for aesthetic appeal
- Minimal maintenance, suitable for 50+ year service life
- Can be used in industrial, residential, and marine-edge environments
- Optional accelerated pre-weathering available
Installation Guidelines for Corrugated Corten Steel
Side overlap: 1 corrugation; End overlap: ≥150 mm
Use stainless steel self-drilling hex screws with EPDM washers
Recommended purlin spacing: 1.0–1.2 m
Ensure sheets laid low-to-high for water runoff
Allow 5–10 mm thermal expansion gap at eaves and ridges
Remove oily residue before installation
Applications of Corrugated Corten Steel
GNEE Corten sheets are suitable for a variety of projects:
- Commercial and domestic roofing
- Wall cladding and feature façades
- Garden structures: pergolas, planters, and screening
- Coastal and marine-edge buildings
- Artistic and landscape installations
Maintenance and Longevity
- Patina formation completes in 6–12 months (faster in humid/coastal areas)
- Annual inspection recommended, wash away debris and salt spray
- Avoid ponding water; maintain minimum roof pitch of 5°
- Typical service life: 50+ years
- Additional Options: Custom lengths from 800 mm to 8 m; Accessories: ridges, eaves trims, verge flashings
For reliable, long-lasting corrugated Corten steel sheets, GNEE offers top-quality products from stock or custom lengths. Ensure your project uses sheets with superior rust-patina finish and minimal maintenance.

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.
