Weathering steels can be used in bridge structures without special paints. Compared to normal steel grades, weathering steel grades provide around 3 × corrosion resistance. However, this is greatly dependent on the severity of environment conditions.

U.S. Steel released the products un-der name of COR-TEN in 1933.
Steel Finishes | Wheeler
Two common steel finishes are weathering steel or paint. Atmospheric Corrosion Resistant Self-Weathering Steel is a special formulation that develops a protective oxide patina. Under acceptable atmospheric conditions the steel rusts to a patina, eventually stabilizing and protecting the steel from further corrosion.SURFACE PREPARATION AND PAINTING STRUCTURAL 5-393.453 BRIDGE CONSTRUCTION MANUAL November 1, 2005. The most common paint systems currently used on new steel bridge elements are zinc-rich primers (organic or inorganic) with an epoxy mid-coat and a urethane top coat. The mid-coat and top coat may also be applied over hot-dip galvanizing with proper surface preparation.SPECIFICATIONS FOR COATING STRUCTURAL STEELSSPC Steel Structures Painting Council AASHTO American Association of State Highway and Transportation Officials ASTM American Society for Testing and Materials 2.2 Related Specifications Specifications for Supply and Fabrication of Structural Steel Specifications for Erection of Structural Steel. 3.0 SUBMITTALS

The surface of weather resistant steel can be painted using the same methods applied in painting ordinary steels. As a result of the special alloying of the steel, a coat of paint can last twice as long as a coating on ordinary steel. If weather resistant steel is continuously exposed to water, it is usually always recommended to be painted.CONTAMINATION OF WEATHERING STEEL DURING requires that all steel surfaces of unpainted weathering steel structures are to be blast cleaned in the shop. Despite precautions taken to protect faying surfaces during the fabrication, transportation, and erection processes, some rusting or contamination of the faying surfaces, by oil, dust, road salts, or cleaning fluids may occur.Analytical Series: Principles of Accelerated Weathering materials is it acceptable to paint weathering steel AssemblingCoatings can possess acceptable appearance after long accelerated weathering times, but then fail due to cracking after a relatively small increment of additional exposure.
