Weathering Steel

Save money and protect the environment.
Naturally weathering steel offers many important benefits.


Big R Bridge Weathering Steel

Big R’s Prefabricated Bridges are available in custom-painted or naturally-weathering finishes. Weathering steel contains elements that allow it to form a protective coating or patina when properly exposed to the atmosphere.

Many bridge engineers choose weathering steel for its environmental performance and economical benefits.

Benefits of weathering steel

  • Reduced toxic emissions: No oil-based coating is used, which reduces emissions of volatile organic compounds.
  • No contaminated blast debris in habitats: Because the steel is not painted, no periodic maintenance blasting is required.
  • Cost savings of 10 percent or more initially and even more over the life of the structure: No painting and steel’s durability mean reduced costs.
  • Long life and high performance: Weathering Steel has been used on bridges for many decades and performs well in most environments.
