Under acceptable atmospheric conditions the steel rusts to a patina, eventually stabilizing and protecting the steel from further cor-rosion. Paint Painted bridges can be considered for applications reopened plants to produce ?weathering steel for bridgesSome results are removed in response to a notice of local law requirement. For more information, please see here.What is the lifespan of a weathering steel bridge?The corrosion rate is so low that bridges fabricated from unpainted weathering steel can achieve a 120 year design life with only nominal maintenance. Hence, a well-detailed weathering steel bridge in an appropriate environment provides an attractive, very low maintenance, economic solution.See all results for this question

Weathering steel - SteelConstruction.info

Weathering steel is a high strength low alloy steel that was originally developed by United States Steel in the 1930s to resist corrosion and abrasion in their ore wagons. It was given the trade name Cor-ten, and was first used in construction on the John Deere World Headquarters building in Moline, Illinois, which opened in 1964.Weathering Steels IspatGuruApr 27, 2013 · Weathering steels corrosion resistance also gives it major advantages over other metals for structures which are exposed to the outside environment.

Weathering Steel - Use & Preparation When Uncoated &

Jun 08, 2018 · Weathering steel, often referred to by the genericized trademark COR-TEN steel, is a group of steel alloys developed to form a stable corrosion-resistant surface after several years exposure to weather, potentially eliminating the need for painting in many environments. U.S. Steel (USS) holds the registered trademark on the name COR-TEN, which refers to the two distinguishing properties of this type of steelWEATHERING STEEL AND COMPOSITE STRUCTURES : environment. With weathering steel, the rusting process is initiated in the same way, but the specific alloying elements in the steel produce a stable rust layer that adheres to the base metal, and is much less porous. This rust patina develops under conditions of alternate wetting and drying to produce a protective barrier that impedesSteel Products- Structural: Allied Steel NJ 888 289-7833ASTM A588 is another High Strength Low Alloy Steel, often referred to as Weathering Steel. Commonly used in bridges, ASTM A588 is utilized moreover for highway construction; its characteristics include a minimum yield of 50,000 PSI and a minimum tensile of 60,000 PSI.
