But what exactly is "Edelrost" (noble rust)? Why is it so popular, and why is there no need to worry about the metal rusting through? In this article, we clarify the most important questions surrounding the topic of rust patina.
What is noble rust?
Noble rust forms on metal through controlled oxidation. It is essentially a protective layer of rust. This patina gives the metal a unique, rustic appearance while simultaneously protecting it from further corrosion. Unlike ordinary rust, noble rust is stable and adheres firmly to the metal.
Longevity: The noble rust layer serves as natural corrosion protection and extends the life of your fence or railing.
Aesthetics: The warm, reddish-brown patina is a beautiful eye-catcher, possesses an individual character, and blends harmoniously into any environment.
Easy care: Noble rust products are extremely low-maintenance and require no special treatment.
Eco-friendly: Noble rust is resource-efficient and sustainable, as it requires no harmful chemicals.
Why you don't have to worry about rusting through
The noble rust layer is not an ordinary layer of rust, but a stable patina that protects the underlying metal. Through controlled oxidation, a dense layer forms that prevents the penetration of moisture and oxygen. This effectively stops corrosion.
Currently, you can see fences or metal decor with a rusted finish in many gardens. However, noble rust is not a passing trend, but an expression of sustainability and appreciation for natural materials. A metal fence or railing with noble rust is an investment in the future that will bring you joy for many years.
What is the difference between rust and noble rust?
While normal rust occurs uncontrollably and damages the metal, noble rust is controlled oxidation that forms a protective patina. Noble rust protects the metal from further corrosion and gives it an aesthetic look.
How do I get noble rust?
Noble rust results from a chemical reaction between iron, oxygen, and water. During the production of noble rust products, this process is specifically managed to achieve a uniform and beautiful patina. It is not recommended to try and produce noble rust yourself, as the result can be uncontrollable.
How do you maintain noble rust?
Noble rust is very easy to care for. Essentially, it requires no special maintenance. Occasionally, you can remove dust and dirt with a soft brush or cloth. Avoid aggressive cleaning agents, as these can damage the patina.
Is noble rust the same as Corten steel?
Yes and no. Corten steel is a steel material specifically developed to form a noble rust patina. Corten steel is the material, and noble rust is the layer of rust that forms on this material.
Can I paint noble rust?
No, you should not paint over noble rust, as the paint would cover the natural patina.
