Characteristics of Corten Steel Retaining Wall
1. Excellent Weather Resistance
The alloy weathering layer of the weathering steel curtain wall contains 4–5% carbon and a high chromium content of 25–35%. This special chemical composition gives the weathering steel curtain wall outstanding weather resistance.
Even under harsh environmental conditions such as high or low temperatures, humidity, or dryness, the curtain wall can maintain its original performance and appearance without rust or corrosion.
This excellent weather resistance makes it an ideal choice for steel structures exposed to the atmosphere for long periods.
2. Good Impact Resistance
The substrate of the weathering steel curtain wall is usually made of low-carbon steel or low-alloy steel with high toughness, providing good impact resistance.
In material handling systems, the curtain wall can withstand impacts and wear from high-drop hoppers and other mechanical actions, ensuring the safety and stability of the building.
3. Reasonable Heat Resistance
The alloy layer of the weathering steel curtain wall contains a high percentage of chromium, which provides good heat resistance. Under high-temperature conditions, the curtain wall can maintain its original performance and appearance without deformation or softening.
4. Good Corrosion Resistance
The high chromium content in the alloy layer also gives the curtain wall a certain level of rust and corrosion resistance. Even in humid or corrosive environments, the weathering steel curtain wall can maintain its original performance and appearance, extending the building's service life.

How long will corten steel last outside?
Generally, Corten steel will patina or rust within six months of atmospheric exposure. Most weathering steel types need wet/dry weather cycles to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years.
What is special about corten steel?
Corten Steel encompasses a group of steels which possess exceptional corrosion resistance and tensile strength. Corten Steel is also known as a 'weathering' steel; as the steel forms a protective layer on its surface under the influence of the weather, and it does not need to be painted.
What does corten steel look like before it rusts?
While many select corten, or weathering steel, because of its practical benefits, others select the steel for the appearance of its rusty, orange-brown patina. However, weathering steel is silver in its original state – just like standard steel. The patina develops over time when exposed to weather.
What is a cheap alternative to corten steel?
Weathering steel possesses the same great properties as Corten steel, but as it doesn't carry the brand name, it costs less. Just like Corten, weathering steel starts out blue-grey in colour and weathers to a rust-coloured finish. The orange patina protects the metal from corrosion and takes 6-9 months to develop.
Does corten steel need to be sealed?
No, Corten steel is designed to naturally form a stable, protective rust layer over time. In standard outdoor settings, this eliminates the need for painting or sealing. However, in aggressive environments, adding a barrier coating can help preserve its structure and appearance.
