Quality requirements and application of bridge steel plate

In fact, the bridge steel plate is not difficult to understand. It is to manufacture the special thick steel plate for 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 the bridge steel plate is 4.5 ~ 50mm. It is used to make highway bridges and railway bridges with riveted and bolted welding structures, including sea crossing bridges.

Carbon steel for bridge construction includes a3q for riveting bridge structure and 16q for welding bridge structure; 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 guaranteed. The cleaning place shall be smooth without edges and corners.

In general, bridge steel plates are mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. they are required to have high strength and toughness, bear the load and impact of locomotives and vehicles, and have good fatigue resistance, certain low-temperature toughness and atmospheric corrosion resistance. Bridge steel plates should also have good welding performance and low notch sensitivity. Bridge steel plate is the main product of our company, so if you want to buy bridge steel plate and other steel plates, you can call our company directly to discuss cooperation.
