The White Rust
The white rust optically disturbs the hot-dipped image although is has no effect on the quality of the surface treatment as well as it does not qualify as a reason for a reclamation. The formation of white rust is related to an inappropriate warehousing and transportation. It is increased by humidity - therefore, transport of hot-dipped material on open platforms in wet or misty weather should be avoided as well as the material's contact with aggressive substances, and if it possible, the material should be kept indoors on dry plates.
