What is Aluminium Coil ?
Aluminium coils are sheets of flattened aluminium rolled into a coil. The width of the aluminium sheet is much greater than its thickness. These coils appear to be hollow cylinders with thick outer edges. Since individual aluminium sheets are difficult to store and carry, industries gradually adopted coiling of aluminium which made it easy to store and transport.

Aluminum Coil Standard Packing Solution
We adopt professional, export-grade packaging for aluminum coils to prevent deformation, scratches, oxidation, moisture and damage during long-distance sea, land and air transportation. All packing solutions comply with international shipping standards, suitable for domestic delivery and global export.
1. Inner Protection
- Anti-rust Paper: Each aluminum coil is fully wrapped with waterproof and anti-rust craft paper, isolating air and moisture to avoid surface oxidation and stains.
- Plastic Film: Double-layer PE stretch film tightly covers the whole coil, enhancing waterproof, dustproof and anti-scratch performance.
- Hard Paper Tube Core: Standard high-strength paper core inside the coil keeps the round shape intact, effectively preventing coil collapse and edge damage during handling.
2. Outer Reinforcement & Edge Protection
- Edge Protectors: Hard plastic or cardboard angle guards are installed on both inner and outer coil edges to resist collision and avoid edge bending, denting and scratching.
- Steel Straps: High-tensile steel bands fasten the packaged coil firmly. Multiple groups of strapping ensure no loose shift in transit.
- Wooden Hoops: Optional wooden ring reinforcement for heavy-duty large coils, further improving structural stability.
3. Outer Packing & Load Mode
Regular Packing
Whole coils are wrapped and reinforced as above, then loaded directly into 20GP / 40GP / 40HQ shipping containers. Coils are fixed with wooden blocks and steel brackets inside the container to prevent rolling and collision.
Wooden Pallet Packing (Popular for Export)
- Aluminum coils are mounted on standard export wooden pallets (plywood / fumigated solid wood pallets, meeting ISPM 15 international phytosanitary requirements).
- Each pallet holds 1 or multiple coils as per size and weight. Pallets are reinforced with steel straps for integral stability.
- Easy for forklift loading, unloading and stacking, greatly improving handling efficiency.
Wooden Crate Packing (For High-precision / High-grade Products)
For mirror aluminum coil, color coated aluminum coil and thin gauge aluminum coil with strict surface requirements, we use fully enclosed fumigated wooden crates. It provides the strongest protection against extrusion, impact and bad weather.
4. Customized Packing Options
- Custom packing weight and pallet size based on clients’ requirements.
- Fumigation certificate, phytosanitary certificate provided for wooden packaging for overseas customs clearance.
- Logo, company name, shipping mark, quantity, weight, spec labels can be printed on the outer package as requested.
5. Shipping Marks & Labeling
Clear permanent labels are attached on each coil/pallet/crate, marking:
Product specification, alloy grade, temper, gross weight, net weight, coil ID, shipping mark and destination. All information is clear for easy inventory and customs inspection.
