Products Description
Q235NH is a weathered steel plate that belongs to the Chinese standard GB/T 4171. It is also known as corten steel or atmospheric corrosion-resistant steel. Q235NH corten steel sheet is designed to have enhanced resistance to atmospheric corrosion, making it suitable for outdoor applications.
The characteristic feature of Q235NH weathered steel plate is its ability to develop a protective rust-like appearance when exposed to the elements. This natural patina acts as a barrier and helps to protect the underlying steel from further corrosion. The rust-like appearance gives Q235NH a distinctive aesthetic appeal, making it popular in architectural and landscaping projects.
Q235NH weathered steel plate offers good mechanical properties, including high strength and excellent weldability. It is commonly used in structural applications such as bridges, buildings, and outdoor sculptures.
Due to its weathering properties, Q235NH corten steel sheet eliminates the need for painting and ongoing maintenance, reducing overall costs. However, it is important to note that Q235NH may not be suitable for highly corrosive environments or areas with high chloride content.
In summary, Q235NH weathered steel plate (corten steel sheet) is a durable and aesthetically appealing material that provides resistance to atmospheric corrosion. Its unique rust-like appearance and mechanical properties make it suitable for various outdoor applications, offering both functionality and visual appeal.

FAQ
Is Corten steel toxic to humans?
No, Corten Steel is not toxic. These environment-friendly materials are completely safe for humans, animals, and plants.
Does corten steel need maintenance?
As mentioned above, corten steel is very low maintenance. However, we do recommend regular checks and cleaning to make up part of a periodic maintenance schedule. Remove any packaging from the product as soon as the delivery is received. Shrink wrap or other packaging materials may cause an uneven patina.
How long does it take for corten steel to rust?
Corten Steel, also known as weathering steel, transforms from its original state of a gray metal color to a beautiful orange-brown color. This process takes place over about three to 12 months, depending on how much the steel is exposed to the elements.
Is corten steel easy to bend?
Straight corten steel: This is the most flexible variant. It is flat and not yet processed, so you can easily bend it.
Does corten steel rub off?
Does corten steel rust rub off on clothes? During the early stages, the rust may rub off on clothes or other materials but, once fully weathered, you will have to rub pretty hard to get anything to rub off.
