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:

DO’s

  • Storage yard should be properly covered.

  • Material should be kept in clean, dry, shaded, good ventilated and plain surface condition.

  • Packing and storage area must be cleaned regularly in order to avoid accumulation of dust and debris.

  • Always clean your hands and use a hand sanitizer before handling Tin plate / Tin free product.

  • Use clean and dry hand gloves to protect the surface of the sheet.

  • Storage and packing area should be free from any form of water contact. In case of presence of water, the sheets must be separated, cleaned and completely dried before using.p>

  • Once the packets/coils are opened, they must be used immediately and should not be held open for a long time without processing

  • Material must be stored indoor on the wooden blocks as suppplied.The storage area must not be humid.

  • Personal hygiene to be maintain for handling of Tinplate products.

  • Rotation on a First-In, First-Out (FIFO), and First-Expired, First-Out (FEFO) basis, whichever applicable

DON'Ts

  • It is recommended to stack the packets/Coils. The packets must not be stacked over a 6 layer level and the coils must not be stacked over a 3 layer level.

  • It is recommended to use the Tin plate / Tin free product within six month ( In packed condition) for Food packaging.

  • Do not reuse the Tin plate / Tin free products for food safety

  • It is recommended to avoid using Defective / Non Standard materials for food-grade applications, as these materials may not meet the quality standards required for products intended for human consumption.

  • 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

Avoiding White Rust to avoid corrosion

The most common causes of White rust to be considered to avoid corrosion are

  • 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
