Bridge building steel plate is usually made from basic open hearth killed steel, should possess high strength and toughness to bear the loads an impacts of vehicles. Besides, it is required to be wear-resistant, atmospheric corrosion resistant, and to have high-quality surface and proper toughness under low temperature. Bolt welded bridge building steel is even required to have proper weldability and low notch sensitivity.
