Our Prefabricated Steel Bridges are available in custom-painted or naturally-weathering finishes. Many bridge engineers choose weathering steel for its environmental performance and economical benefits.
Weathering steel contains elements that allow it to form a protective coating or patina when properly exposed to the atmosphere. The first bridge using this material was built over the New Jersey Turnpike in 1964.
Friend of the environment.
Weathering steel provides environmental benefits as well. It does not require initial painting, thereby reducing emissions of volatile organic compounds (VOC) when oil-based coatings are used. Nor does it require coating removal or disposal of contaminated blast debris over the life span of the structure, providing another significant environmental benefit.
Friend of the budget.
The use of weathering steel typically provides initial cost savings of 10 percent or more, and life cycle cost savings of at least 30 percent over the life of the structure. Initial cost savings are realized because weathering steels do not need to be painted. Life-cycle cost savings are realized by the material’s durability. Inspections of bridges in service between 18 and 30 years show that weathering steel performs well in most environments.
