What are the characteristics of pre weathered corten steel plate after being rusted

Pre weathered corten steel plate is made by adding a small amount of weatherproof elements such as copper and nickel into ordinary carbon steel. It has certain weatherproof performance in practical application. Therefore, Pre weathered corten steel plate is widely used in many buildings and bridges. Pre weathered corten steel plate is not stainless steel plate. It will also produce rust after contacting with the atmosphere. Let's learn about the characteristics of pre weathered corten steel plates after rusting.

Pre weathered corten steel rust layer is the oxide of many kinds of alloy elements, which is reddish brown. The rust layer is very dense, which prevents further corrosion of steel plate. It also has the characteristics of weatherproof and non-corrosion. However, it takes a long time to form this layer of rust under natural conditions, so in general, artificial means will be adopted to promote the formation of rust layer. Rusty steel plates with full reddish brown are often beautiful as landscapes. Pre weathered corten steel plate rusts in natural climate, which forms a dense oxide layer between rust layer and matrix. Because of the existence of this dense oxide film, oxygen and water in the atmosphere are prevented from infiltrating into the steel matrix, thus improving the atmospheric corrosion resistance.

This corrosion will gradually change into different colors over time, which will make it possible in many landscape designs. It can enhance the heavy texture of the landscape.
