Bridge Steels and Corrosion Protection Civil EngineeringOne of the most important decisions designers have to make is selection of the proper grade of steel and corrosion-protection system. These should not only meet
Carbon and Low-alloy High-strength Steel provide greater environmental corrosion resistance and are stronger than convention carbon steel,also very ductile, highly formable and easy to weld.Carbon and Low-alloy High-strength Steel steels are not typically made to meet a certain chemical composition, instead they are known to meet specific mechanical properties.
Cost-Effective Plate-Girder Designs Civil Engineering2. Properly designed for their environment, unpainted weathering-steel bridges are more economical in the long run than those requiring painting. Consider the following grades of weathering steels:ASTM A709 grade 50W, 70W, HPS70W, or 100W. Grade 50W is the most often used. 3.
