Figure 4: Cold-rolled coils packaged in scrap sheet metal on skids stored outside without protection from the weather. There is nothing to stop water from penetrating the package via the edge protectors and causing corrosion on the coil. Moreover, the skid of the coil placed on the second layer will leave pressure marks on the underlying coils. Coils on skids should only be stored in a single layer. [Mund & Bruns]
