10 Best Ways to Prevent Gusset Plate Corrosion

WebDec 29, 2024 · However, low corrosion resistance of carbon steel can result in severe deterioration of bridges. As a result, a very high maintenance cost may be incurred during the service life of carbon steel bridges. A new type of corrosion-resistant steel, A709-50CR, has been recently developed for bridge construction. WebThe results showed that the galvanized weathering steel had performed well on a bridge for 6 years without any major issues. The steel plate meeting the chemistry requirements of ASTM A1035CS showed good corrosion resistance and material properties, and further research is recommended to determine its suitability for use as a steel bridge material. tbtools 火山图导出 https://boxh.net
