What is the application advantage of Q345NH weathering steel plate in bridge engineering?

With the expansion of the Q345NH weathering steel plate market, weathering steel plate has gradually become the main material of bridge engineering, which has gradually increased the service life of bridges. Let us take a look at the advantages of Q345NH weathering steel plate in bridge engineering.

1. Corrosion resistance: We all know that many bridges are designed close to the water. Some even cross-sea bridges, whether in sea or river water, will have high tide, which will flood the bridge deck. This places high demands on the materials of the bridge. If ordinary steel is used, corrosion will quickly occur. The application of Q345NH weathering steel plate in bridge engineering can effectively reduce these corrosion phenomena and make the bridge construction stronger.

2. Q345NH weathering steel plate will rust naturally after being used for a period of time. The color of this rust will change over time. This color element has been added to the design of many buildings to achieve a heavy effect. The use of weathering steel plates in bridge engineering actually adds a heavy texture to the bridge.

3. Improve the service life: After corrosion, a dense oxide film will form on the surface of the weather-resistant steel plate, which closely isolates the base layer from external corrosion, thereby protecting the base layer material from corrosion. This function can extend the service life of the bridge.

The application advantages of Q345NH weathering steel plate in bridge engineering can understand that weathering steel plate in the construction industry can play its own performance advantages to a large extent, so weathering steel plate brings great benefits to the construction industry.
