What does weathering steel mean?

October 05, 2023

Weathering steel is a type of steel that is specifically designed to resist the effects of weathering. Weathering steel is also known as CORTEN steel, which is a trademarked name that refers to specific corrosion-resistant alloys that are used in the construction of various products such as outdoor sculptures, building facades, and bridges.
The main characteristic of weathering steel is its ability to resist corrosion due to exposure to the elements. This corrosion resistance is achieved by the formation of a protective layer of rust, which forms on the surface of the steel. The rust layer acts as a barrier that prevents further corrosion, protecting the underlying metal from damage.
Weathering steel is often used in outdoor applications where exposure to extreme weather conditions is unavoidable. This includes structures such as bridges, buildings, and sculptures. It is also commonly used in marine environments due to its ability to resist corrosion from saltwater exposure.
One of the unique features of weathering steel is its appearance. As it ages and weathers, it develops a distinct patina that gives it a rustic, industrial look. This patina is highly valued by architects and designers for its aesthetic qualities.

In summary, weathering steel is a specialized type of steel that is designed to resist corrosion from exposure to weathering. It is valued for its durability and unique appearance, making it a popular choice for a variety of outdoor applications.

Why is the rust on the surface of weathering steel better? Corrosion under natural climatic conditions causes a fine oxide layer to form between the rust layer and the substrate. Due to the existence of the oxide film, oxygen and water are prevented from entering the matrix from the air, thus improving the ability to resist atmospheric corrosion. Steel is often referred to as "the synonym of the industrial age", "the concept of time in visual representation", "the label of the concept of technology and civilization", and is widely used.

Weathering steel, also known as atmospheric corrosion resistant steel, commonly known as rust steel landscape weathering steel, is widely used in gardens, can be directly exposed to the atmosphere without painting. This is because the surface has a layer of dense and protective film with strong adhesion, which can hinder the spread and development of rust, protect the matrix below the rust layer, and greatly improve the atmospheric corrosion resistance of steel materials.
