White Rust, Transport, Warehousing

The formation of white rust implies the presence of humidity, and white rust disturbs the hot-dipped image although is has no effect on the quality of the surface treatment and does not qualify as a reason for a compliant. The formation of white rust coincides with inappropriate warehousing and storage - 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 possible, the material should be kept indoors on dry plates and should not be covered with foil.
