In the past, corrosion resistance was not regarded as the most important factors to choose bridge steel. Then the pursuit of large span, high strength, low flexion and strength ratio, low temperature toughness and weldability and homogenization of thick steel plates, are necessary conditions for application of weathering steel plates in bridge. The economy, bridge aesthetics and fatigue resistance of ASTM A242 Type 2 weathering steel plates have been paid more and more attention in recent years.
We should exactly know the corrosive environment of ASTM A242 Type 2 weathering steel plates; setting clear critical standard for all kinds of environmental pollution according to the actual work environment. Then we can make a better choice of painting, stabilizing or directly exposed of ASTM A242 Type 2 weathering steel plates.
The close coopertaion of ridge design, materials development, corrosion control professionals; and supporting the establishment of relevant standards and norms for ASTM A242 Type 2 etc. weathering steel; continuous follow-up investigation for application result, making economic analysis according to the life cycle theory is very important for expanding application of ASTM A242 Type 2 weathering steel plates in bridge.
