Packaging Export Steel Coils: Full Process Revealed with Rust‑Prevention Paper, Straps, and Pallets
As the world’s largest exporter of steel coils, China ships millions of tons of steel to international markets each year. Therefore, how to protect these products during long-distance transport is a significant issue. Packaging methods like using rustproof paper, strapping, and palletization as essential steps.
To prevent steel corrosion, exported coils are commonly wrapped with vapor-phase anti-rust paper or laminated waterproof materials. These materials help to isolate moisture and oxygen which help to shield the steel from damage caused by humid marine environments.
To securing the coils from moving, companies typically use steel straps or PET (polyester) straps. Steel strapping could offers superior tensile strength in delivery which is ideal for heavy cargo. Meanwhile, PET strap is known for their flexibility and resistance to shock. Additionally, it have gained popularity as an eco-friendly alternative, especially in global markets.
Pallets serve as the base support for coil stacking and transport. Whether made of wood or steel, these pallets must comply with Chinese national standards (such as GB/T 4995 and GB/T 2934) to ensure compatibility with truck, rail, and maritime logistics. Pallet height is also designed to accommodate forklifts and minimize direct moisture contact.
To avoid edge deformation and damage from strapping pressure, protective components like corner guards and internal/external rings are added. Other auxiliary materials such as foam pads, cardboard cushions, and inflatable dunnage bags help absorb shock and prevent surface abrasion.
During container loading, moisture barriers like PE liners are laid at the base, and desiccant packs are inserted. Some exporters even use aluminum foil composite bags for added sealing. Industry recommendations—such as those in export packaging guidelines for coated coils—advocate a layered protection approach.
Each coil package must stick compliant labels including detailed specifications, weight, handling instructions, and its destinations. All markings must follow the GB/T 247 standard to facilitate accurate identification in order to ensure the operating accuracy across logistics channels.
In sum, packaging for export steel coils has become a standardized, end-to-end system, covering everything from in-factory wrapping to container loading. A well-executed packaging solution not only protects the cargo during multimodal transportation but also enhances China’s steel competitiveness in the global market.
As sustainability becomes a growing priority in international trade, packaging for export coils is also shifting toward recyclable materials and smart packaging technologies—ensuring safer, greener, and more efficient supply chains for the future.
