Finish Options

Big R Bridges are renowned for their high-quality finishes.

Choose from a traditional weathering steel finish, creative paint scheme or long-lasting galvanized or metalized finishes to set your bridge apart for decades of service.



A weathering steel superstructure is an economical choice, with a unique appearance that complements outdoor settings. Weathering steel naturally oxidizes to provide a protective patina that does not require painting. The color will vary regionally from dark brown to orange tones. Weathering steel brings several key benefits:

  • 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.


Sophisticated paint finishes can add another level of interest to an already stunning bridge. Architects, engineers and owners alike, specify factory-applied paint finishes to align their designs with neighboring structures or other urban design features.

Hot-Dip Galvanized

Commonly used in coastal areas, a hot-dip galvanized finish increases the lifespan of a bridge by adding a metallurgically bonded zinc layer to the structural steel members. Speak to a Big R Bridge Technical Sales Representative to learn more about component size limitations during the hot-dipping process.

metalized finish


Metalizing is a process where zinc and/or aluminum is thermally applied to the steel surface. This finish provides a very uniform coating allowing for an additional clear or painted top coat as required.
