Bridge Steel Plate China Quality identification and application of bridge steel plate In fact, it is not difficult to understand by analyzing the name of bridge steel plate. Bridge steel plate is a special thick steel plate for manufacturing bridge structural parts. It is made of special steel, carbon steel and low alloy steel for bridge construction. The end of the steel number is marked with Q (bridge). The thickness of bridge steel plate is 4.5 ~ 50 millimeters. It is used for making highway bridges and railway bridges with riveted and bolted welding structures, including sea crossing bridges. Bridge steel plates include a3q for riveting bridge structures and 16q for welding bridge structures; Low alloy steels for bridge structures include 12mnq, 12mnvq, 15MnVNq, 16Mnq, etc. The surface of the bridge steel plate shall be free of cracks, bubbles, scabs, folds, inclusions and delamination. If the above surface defects are allowed to be cleaned, the cleaning depth shall not be greater than half of the steel thickness tolerance from the actual size, and the thickness shall be small. The cleaning place shall be smooth and free of edges and corners. Bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. it is required to have high strength, toughness, bear the load and impact of locomotive and vehicle, and have good fatigue resistance, certain low-temperature toughness and atmospheric corrosion resistance. Bridge steel plate should also have good welding performance and low notch sensitivity. There is a lot of information about bridge steel plate.
