CORROSION RESEARCH ROUND‐UP

GERMANY Corrosion of steel‐sheet piling. About 30 years ago, a beginning was made with adapting the Dortmund‐Ems Canal to modern traffic requirements. On that occasion, much use was made of steel‐sheet piling for the protection of the banks. After the war, the condition of the old sheet piling had to be investigated in order to determine to what extent this method should be used for the remaining work. In particular, the extent of corrosion and the points where corrosion was most pronounced had to be ascertained so that the findings might be used to help choose the steel‐sheet piling to be employed in future. The investigations were carried out by the German waterways administration in conjunction with a company of steel‐sheet‐piling manufacturers.
