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.Steel plates for bridges are required to have high strength, toughness, bear the load and impact of locomotives and vehicles, and have good fatigue resistance, certain low-temperature toughness and atmospheric corrosion resistance. The steel used for bolting and welding bridges should also have good weldability and low notch sensitivity.
