Q420qENH weather-resistant bridge plate production and application: Q420qENH spot

Q420qENH belongs to the weathering bridge steel plate. Compared with the traditional bridge plate, Q420qENH steel plate has a great improvement in welding performance and toughness, and has a significant effect on corrosion resistance in atmospheric and marine environments. Q420qENH bridge slabs are mainly used in bridge construction.
