Want to add an interesting visual feature to your garden landscape while keeping it as low maintenance as possible? Corten steel is ideal for creating raised beds and rock garden edging. The warm colour gives a rustic feel, while the durable material withstands all types of weather without needing added treatment. Is your lawn sloped and difficult to work with? Give it a natural, gentle flow by using cor-ten steel to make a descending pathway.
corten steel garden edging
Corten is a versatile metal-flexible and sturdy and virtually maintenance-free. It's no wonder designers are so crazy about it. Corten or weathering steel is typically used for landscaping and outdoor construction. It is made with alloys that cause its surface to develop a self-protecting rust when exposed to weather. The insulating patina resists corrosion, requires no painting or weather-proofing, and doesn't compromise structural strength.
FAQ
How long does it take for Corten steel to rust?
With the help of this unique mixture, Corten can weather naturally and eventually take on the appearance of stable rust, which we call patina formation, following a certain amount of exposure to air, sun, and rain. Corten gradually begins to change over time, usually in the course of several months to a year.
What are the pros and cons of Corten?
While it has a greater starting cost than typical steel and is unsuitable for severely corrosive conditions, its benefits frequently exceed these disadvantages. Overall, corten steel is a popular metal fabrication material due to its appealing mix of utility, aesthetics, and durability.
Is Corten steel hard to weld?
Despite its benefits, welding corten steel comes with some challenges: Heat-induced distortion or cracking. Loss of corrosion resistance near the heat-affected zone. Difficulty in matching the patina formation post-weld.
Can rusted steel be repaired?
If the metal already has surface rust, you can clean off the rust mechanically by sanding it or chemically with a rust remover like ERW-XL Rust Remover. Once the rust is removed and the metal looks the way you want it, Everbrite Coating or ProtectaClear will seal the metal and help prevent future rust.
Why is corten steel so expensive?
Corten steel is more expensive due to the materials used and the specialized production process. Traditional steel rusts and is therefore a less suitable choice for outdoor applications. Polyester is cheaper than corten steel, but does not withstand temperature changes as well and can become porous over time.
