12.09: Weathering steel – 30 years of experience in Banedanmark

Banedanmark has used weathering steel for more than 30 years and has gathered unique information about corrosion of weathering steel during this period. Not only has the corrosion rates been noted – but also the good and poor detailing. The conclusions of this will be given in this paper. Based on the information gathered from the tests, a method for estimating the corrosion lifetime for the specific type of structure is given.
