Preventing Coating Damage to Sheet Materials During Transportation: Essential Knowledge

Sheet material transport damage shows up the day your customer unwraps the container: scratches on copper, rust at the coil edge, PVC film torn. Consequently, packaging and loading decide whether your order arrives sellable or scrap. Here are the three damage sources and how we prevent each.

Damage Source 1: Physical Scratches and Impact

Sheet shifts in the container. Metal-to-metal contact causes scratches. Furthermore, forklift forks dent plate edges. To prevent this:

  • Wrap each bundle in PVC film.
  • Separate layers with corrugated board or VCI paper.
  • Strap bundles to pallets, not loose in the container.
  • Use forklift spreader bars, not single forks.

Consequently, the material arrives without handling marks. We pack C11000 / T2 Copper Plate with PVC film both sides and edge protectors.

Damage Source 2: Moisture and Rust

Ocean containers swing 20–40°C in temperature. Consequently, condensation forms inside. Moisture collects at the coil edge and on bare steel. To prevent this:

  • Use VCI (volatile corrosion inhibitor) paper.
  • Add desiccant bags inside the container.
  • Keep bundles off the container floor on dunnage.
  • Seal the container door with waterproof tape.

Furthermore, tinplate and copper need dry containers, not reefers. We ship C12200 / TP2 Copper Tube with end caps and VCI paper.

Damage Source 3: UV and Temperature

Sunlight through the container wall heats the steel. Furthermore, UV degrades PVC film and paint. Consequently, the film becomes brittle and peels. To prevent this:

  • Ship in dry containers, not open-top.
  • Avoid reefer containers unless specified.
  • Keep cargo away from container side walls in summer.

How We Pack Every Order

Before shipment, we:

  1. Clean and inspect the surface.
  2. Apply PVC film for polished or copper stock.
  3. Add VCI paper for ocean freight.
  4. Strap to wooden pallets with steel bands.
  5. Mark grade, heat number, and dimensions on each bundle.

Consequently, your warehouse identifies stock at a glance and rejects damage claims at the port.
