STORAGE AND HANDLING
If colour coated sheets are to be stored for any time prior to forming or installation, they must be stored in dry, well ventilated conditions. Storage which allows water (including condensation) to be trapped between the sheets may damage the coating beyond repair
Some Do’s and Don’ts that needs to be followed as below
Always keep material in a dry, shaded and good ventilated area
If not required for immediate use, provide cover to protect the material
If Sheets become wet during storage, it should be separated without delay & surface moisture removed with clean cloth.
The steel sheets then be stacked so that air circulation completes the drying process
Material to be kept slightly above the ground by using wooden rubber plank
Do not keep the material on wet floor (water, rain. etc.)
Moisture or water penetration between the sheets through the wooden pallets which causes damage hence to be avoided
Prevent water seepage inside the packed coils and packets
Metal-on-metal contact should be avoided whenever possible
Under no circumstances should the material be stored near or come in contact with salt water, corrosive chemicals, ash, or fumes generated or released inside the building or nearby plants, foundries, plating works, kilns, fertilizer, and wet or green lumber
Do not slide sheet on rough surface or over each other
Contact with water and mud should be strictly prohibited
Avoiding White Rust to avoid corrosion
Ingress of water in a stack of colour coated sheets to be avoided
Condensation within a coil or sheets due to rapid changes in temperature
Prolonged/adverse storage or inadequate protection during transportation allowing considerable water ingress between stacked coils or sheets results into red rust
