How to Ship Steel Coils Internationally

With over 25 years of logistics experience, Shipping International understands the unique demands and risks associated with the international transportation of steel coils. These coils, vital to Automotive, construction, and machinery sectors, require exceptional planning, equipment, and care to avoid potentially catastrophic damage during transit.

Understanding the Risks: The Rolling Pin Effect

Steel coils are dense and cylindrical, perfect candidates for what we call the rolling pin effect. An unrestrained coil in motion can generate immense kinetic energy, damaging containers, vehicles, or port facilities, and even endangering lives. This underscores the importance of choosing a reputable logistics partner with the technical know-how to get it right the first time.

Pre-Shipment Preparation

Begin by providing a precise cargo description: weight, dimensions, steel grade, and orientation preference (e.g. Eye to Sky or Eye Fore and Aft). This information shapes container selection, lashing strategy, and insurance needs. Reference our cargo dimensions guide for best practices.

Container Selection and Weight Distribution

Always use certified 30-tonne 20-foot containers, ideally Grade B or higher. These are proof-tested to handle concentrated loads. Never allow a steel coil to rest directly on the container floor always employ heavy-duty timber or steel supports to distribute weight across multiple cross-members. For guidance, see our container FAQs.

Safe Coil Orientation and Securing

Each coil orientation carries distinct risks and requirements:

• Eye to Sky: Use pallets and lashings. Suitable for small coils.
• Eye to Side: High rolling risk. Requires precise blocking and transverse lashing.
• Eye Fore and Aft: Demands cradles and extensive longitudinal securement.

All lashing systems must comply with the “fuse principle” no strap should exceed the breaking strength of the container lashing ring. Aim for total restraint strength ≥ 5× the coil’s weight.

Forklift Handling and Floor Integrity

Comply with ISO 1496/1 to avoid floor damage during loading. Forklift axle weight must not exceed 5,460 kg, and tyre contact areas must meet specific surface area and spacing criteria.

Prohibited Practices

Never load a coil without bedding or rely on container walls for bracing. Non-compliant practices can lead to floor failure or breach of structural integrity, potentially incurring repair costs exceeding £1,000. Learn more in our shipping documentation guide.

Documentation and Insurance

Include export/import permits, customs forms, and Certificates of Origin. Securing comprehensive cargo insurance is essential. We recommend cover aligned with Institute Cargo Clauses A for maximum protection.
