ASTM A242 Type 2 corten steel plates get popular in bridge building

Long time ago, when choosing raw materials, the bridge engineers usually put large span, high strength, low flexion and strength ratio, low temperature toughness and weldability and homogenization etc. features of the bridge use steel materials at the first place. While corrosion resistance of ASTM A242 Type 2 corten steel plates etc. steel materials was not emphasized so much then.

With the economy development, the bridge building also puts higher requirement for raw steel materials. With excellent bridge aesthetics and fatigue resistance as well as corrosion resistance etc. characteristics, ASTM A242 Type 2 corten steel plates get popular in bridge building.

During ASTM A242 Type 2 corten steel plates application in bridge, we should be clear about the actual work environment. Generally, ASTM A242 Type 2 corten steel plates can directly expose to the atmosphere without painting. But if the work environment is too moisture or corrosive, we can also consider to do painting at surface.
