What are the advantages of weathering steel in bridge application?

With the development of China's construction industry, we can see that many cities have new viaducts, and now the level of bridge construction in our country is also constantly improving, the service life of the bridge is getting longer and longer, which is inseparable from the extensive use of weathering steel, because the bridge needs to be exposed for a long time, so its performance requirements are also very high.

1. Corrosion resistance: the design of many bridges is close to the water surface, and some even cross sea bridges, whether it is sea water or river water, how much will appear the phenomenon of rising tide, so as to submerge the bridge deck, which has high requirements for bridge materials. If ordinary steel is used, corrosion will soon occur, and the application of weather resistant steel plate in bridge engineering can be effective These corrosion phenomena are reduced and the bridge construction is more solid.

2. Beauty: the weathering steel plate will naturally rust after using for a certain period of time. The color of the corrosion can be changed with the change of time. This color element has been added in the design of many buildings to achieve the heavy effect. The use of weather resistant steel plate in bridge engineering virtually adds a layer of thick texture to the bridge.
In addition, it is very important that weathering steel can increase the service life of the bridge and protect the base material from corrosion. This is also an important reason why it has been recognized by more and more people.
