The Corrosion Prevention Research of Long-Span Non-Uniform Continuous Steel Bridges

As its good mechanical properties, steel bridge has been widely used in modern highway, railway and urban bridge construction, but its corrosion protection is also a major issue. This paper studies the types of corrosion, the methods of anti-corrosion and focuses on coating protection--the most promising anti-corrosion method currently. It proposes some improvement measures for the corrosion protection, and has a certain reference value for the design and construction of such bridges.
