Figure 1: Metal sheets in packages on wooden skids. The wooden skids are too small because the corners and edges of the packages extend beyond the skids and are thus unprotected.  In addition, the packages have already been deformed by handling and transport operations. The cover sheets are mainly corroded due to storage in the open. Moisture could, for example, have penetrated the package and if the inner packaging (if there is any) is in the least damaged may have caused corrosion damage to the sheets. [Mund & Bruns]
