What are the main characteristics of bridge steel plate

Bridge steel plate is made of carbon steel and low alloy steel for bridge construction. Generally, the thickness of bridge steel plate is between 4.5-50mm. There are many types of bridge steel plates, such as bridge plate Q345QD, bridge plate Q370QD, bridge plate A709, etc. Bridge steel plate can be used to make highway bridges, railway bridges, sea crossing bridges and so on.

Bridge steel plate has good strength and toughness, corrosion resistance, acid and alkali resistance. The static bending strength of bridge steel plate is 8-10 times of wood strength, 4-5 times of wood plywood, and its surface can be processed. Since the bridge steel plate is used to make the bridge, it naturally needs to have a good water resistance. The surface of bridge steel plate is very smooth, the surface can be poured without plastering, which can reduce the workload and shorten the construction period. The service life of bridge steel plate is very long, which can ensure the normal use of the bridge after being put into use.
