Corten steel is a popular type of steel often used in outdoor construction due to its high tensile strength and corrosion resistance. However, there are some drawbacks to using this type of steel.
One of the biggest disadvantages of Corten steel is the cost. Although the price of this material is higher than traditional steel, its decorative appeal and long-term durability can help make up for the added cost.
It’s also far heavier than more traditional steel, making it difficult to transport and install.
Another disadvantage of Corten steel is its lack of strength when exposed to certain elements. Corten steel is prone to rusting when exposed to certain elements such as high humidity, rain, or salt water.
As a result, its structure may weaken over time and require additional support in certain areas.
Finally, Corten steel is not the most aesthetically pleasing option. Its rust-like orange-brown patina may not fit with modern design preferences, leaving architects and designers struggling to find a way to incorporate the material without harming the aesthetic.
What is special about Corten steel?
Corten steel is a special type of steel alloy that is designed to form a rust-like layer on its surface when exposed to the elements. The material was initially designed and developed in 1930, by the United States Steel Corporation, and was later trademarked by U. S.
Steel under the brand name Cor-Ten. The distinctive reddish-brown color is a result of a coating of rust that forms when the steel is exposed to extreme weather conditions. This layer of rust provides a protective layer that helps to prevent further deterioration from moisture and oxidation.
The ability to withstand extreme weather conditions is what makes Corten steel a great choice for construction projects. It is able to maintain its strength and durability over time while having little to no maintenance.
Because of its aesthetic properties, Corten steel is also becoming more popular in architectural applications, such as in outdoor sculptures, public art installations, green roofs, and more.
What is the difference between steel and Corten steel?
Steel is a metal alloy that is made up of iron and carbon, along with other elements such as trace amounts of chromium, manganese, tungsten, molybdenum, and nickel. It is corrosion-resistant and strong, making it a popular choice for structures and infrastructure projects that are exposed to the elements, as well as for use inside buildings and homes.
Corten steel is also a metal alloy, but with a higher level of corrosion resistance. It is made up of iron, chromium, nickel, and copper, with trace amounts of other metals like manganese and phosphorus, as well as small amounts of other elements like vanadium and titanium.
The difference between steel and Corten steel is that Corten contains additional alloying elements, which give it improved strength and corrosion resistance compared to regular steel. Corten also does not require additional coating or rust treatment, making it an excellent choice for outdoor projects that are exposed to the elements.
How long does Corten last?
Corten steel can last for many years, depending on the environment it is exposed to and the type of maintenance performed. If properly maintained and not exposed to corrosive materials, Corten can last upwards of 80 years or more.
Corten steel is commonly used in outdoor applications such as sculptures, bridges, buildings, fences, and other outdoor structures. These structures are often exposed to rain, snow, wind, and other environmental elements, so it is important to ensure adequate maintenance is performed.
Adequate drainage and painting of the steel can help prolong Corten’s life by preventing the build-up of rust and corrosion. In addition, protective coatings, such as sealants, wax, or primer, can help increase Corten’s longevity.
In most cases, Corten can outlive traditional steel, and when properly cared for, can last for centuries.
Can you prevent Corten steel from rusting?

Firstly, it is important to keep the Corten steel clean. This can be done through a variety of methods such as power washing, or cleaning with a mild detergent. It is important to refrain from abrasive cleaning as this can damage the rust patina on the steel.
Secondly, it is important to protect the steel from any areas that may collect water. This includes the crevices and any seams. Areas that allow water to pool can corrode the steel more quickly. If water does.
Can I seal corten steel?
Yes, you can seal corten steel through basic methods but doing so isn’t always recommended. Sealing corten steel can generally be done through either a spray-on or brush-on sealant may be needed to mitigate the effects of weathering, although some people prefer to just let the material weather over time.
You can also use rust inhibitors, which are applied with a brush or spray and are typically water- or oil-based. Additionally, there are products on the market specifically made for sealing corten steel, such as paints and glazes.
Regardless of the method you use, it’s important to apply any sealant yearly for maximum protection.
Does Corten flake?
No, Corten does not flake. Corten steel is a type of alloy that was developed to form a stable rust-like appearance after several years when exposed to the elements. It’s generally used in architecture and structurally sound uses where appearance is a priority since it offers an aesthetically pleasing dark orange-brown colored surface.
Corten is also known for its high tensile strength and corrosion resistance properties, which make it an excellent choice for a wide range of applications. As a weathering steel, Corten does not flake or chip during weathering and is preferred for structures where staining is not a desirable feature.
Is corten steel sustainable?
Yes, corten steel is considered a sustainable building material. Corten steel, also known as weathering steel, has a unique combination of corrosion resistance, durability, and aesthetics that make it a popular choice for architectural and landscape designs.
Corten steel is created through the process of allowing metal to react with the elements, in a controlled environment, which makes it weather resistant and able to last for generations. In addition, corten steel is known to be more energy efficient than other steel materials, due to its ability to absorb and efficiently reflect sunlight.
This can lead to lower energy costs associated with heating and cooling. Finally, its long lifespan means that it could potentially reduce overall building material costs over the life of the building.
