Bridge steel plate is dedicated to the construction of railways or highway bridges. Requiring a higher strength, toughness and bear the load and impact of locomotives and vehicles, and have a good anti-fatigue, a certain low-temperature toughness and resistance to atmospheric corrosion.
Railway or highway bridge to withstand the impact load of the vehicle, the bridge steel requires a certain strength, toughness and good fatigue resistance, and the steel surface quality requirements are higher. Bridge steel often use alkaline flat furnace cast steel, the successful use of ordinary low-alloy steel such as 16 manganese, 15 manganese alum nitrogen (YB168-70) tied bridge steel should also have good welding performance and low gap sensitivity.

The A709 steel, which is composed of iron, manganese, carbon, and other elements, maintains an excellent strength-to-weight ratio. This means that smaller quantities of steel are required in order to meet our customer's varying strength requirements, improving efficiency and cutting down on excess weight.
A709 steel also maintains excellent corrosion resistance, allowing it to maintain long lifespans-even during the most harsh atmospheric conditions. These properties make A709 steel ideal for applications such as bridges, and is a standard material employed by the American Association of State Highway and Transportation.
