Storage and Transport
Store all steel and steel related products in a stable configuration. Avoid contact with corrosive agents such as acids, alkalis and salts. Transport in accordance with Government Regulations and always ensure load is secure.
With Zinc coated, Aluminised or ALLGAL® products, attention should be paid to the conditions of transport and storage to avoid the possibility of damage or wet-storage stain.
A corrosion known as white rust can occur on freshly Zinc coated products that are transported or stored under damp and/or badly ventilated conditions. The corrosion is frequently superficial despite it’s bulkiness. It may be unattractive, but is not usually detrimental to the other properties of the coating.
The packed product should be kept undercover in clean, dry and ventilated conditions. This is especially important for products in the lower size range as their bundle configuration restricts natural ventilation. Storage under covers which restrict ventilation (e.g tarps) is not recommended.
If products have to be stored outside, then the packs should be broken up and stacked with a wooden spacer between each layer. The stack should be on an incline so that any water can run off the product. Products should never be stored in contact with cardboard or paper products, cinders, clinkers, unseasoned timbers or harmful chemicals. White rust can be removed with a high pressure water cleaner, scrubbing brush or soft scouring pad. Kerosene is also a good agent for the removal of white rust. If the Zinc or ALLGAL® coating is subject to excessively rough treatment and some damage does occur, the area should be cleaned and touched up with one of the following coatings:
-
Organic Zinc-rich primer; or
-
In-organic Zinc silicate paint; or
-
Zinc metal spray.
These coatings should be applied in accordance with manufacturer recommendations.
