high strength astm a709 bridge steel plates

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.
