What Kind of Packaging Is Suitable for the Safe Ocean Transportation of Steel Coils?

If you are importing steel coil galvanized, PPGI Steel Coil, Cold rolled steel Coil, or other flat steel products, you must ask: what kind of packaging is suitable for the safe ocean transportation of steel coils? The answer is critical. Poor packaging leads to rust, edge damage, telescoping, and costly claims. This guide explains the industry‑standard packaging methods that ensure your coils arrive in perfect condition.

Why Ocean Transportation Requires Special Steel Coil Packaging

Steel coils are heavy and dense. A single coil can weigh 5–25 tons. During ocean transit, vessels roll and pitch, and containers are stacked and shifted. Without professional steel coil packaging, the risks include:

Rust & corrosion from salty, humid air

Edge damage from strapping or impact

Telescoping – layers slide sideways, ruining the coil

Shifting inside container, causing accidents

That is why experienced steel coil manufacturers and steel coil companies follow strict steel coil package standards for export.

The 4 Essential Layers of Proper Steel Coil Packaging

1. Inner Protection – Moisture Barrier

The coil is wrapped with VCI (Vapor Corrosion Inhibitor) paper or film. This prevents condensation from attacking the steel surface. For gi coil or gl coil, this layer is especially important to keep the zinc or aluminum‑zinc coating intact.

2. Waterproof Outer Wrap

A heavy‑duty polyethylene or PVC film is wrapped around the VCI layer. It seals out sea water and humid air. Steel coil hot (hot rolled) is less sensitive but still needs this protection; cr coil (cold rolled) and PPGI Steel Coil (pre‑painted) demand a perfect barrier.

3. Edge Protection

Cardboard or plastic edge protectors are placed around the inner and outer circumferences. Without them, steel strapping cuts into the coil edges, causing damage that makes the material unusable for high‑end applications.

4. Securing – Steel Strapping

High‑tensile steel straps are applied – usually through the eye (center) and around the circumference. The number and strength of straps depend on steel coil size and steel coil length. Proper strapping prevents telescoping and shifting.

Additional Measures for Safe Container Loading

Even the best steel coil packaging fails if the coil is not blocked inside the container. Common practices:

Wooden cradles or dunnage – Coils rest on shaped wooden supports that distribute weight and prevent rolling.

Air bags – Inflatable bags fill gaps between coils and container walls.

Through‑the‑eye strapping – Straps passed through the coil’s center and anchored to container floor rings.

These steps are routine for experienced steel coil factory exporters like us.
