Steel Coil Protection Board (also known as Steel Coil Protection Material) are rigid or semi-rigid sheet materials used for the outer protection of steel coils. They are typically used in conjunction with flexible materials such as wrapping film and anti-rust paper to form a multi-layer composite protection system.
Steel Coil Protection Board are typically made of galvanized steel, cold-rolled steel, aluminum alloy, or high-strength composite materials. Thicknesses (0.5mm-3mm) and structural forms vary depending on the weight of the coil, transportation distance, and storage environment.
Functions of Steel Coil Protection Board
- Mechanical Protection: Resists impact, crushing, and scratching during transportation and lifting, preventing damage to the coil edges.
- Moisture and Rust Protection: Steel Coil Protection Board, combined with vapor-phase anti-rust paper and plastic film, isolate moisture and oxygen, slowing oxidation of the coils.
- Structural Support: Provides stability during stacked storage, preventing steel coils from deforming or collapsing.
Common Types and Applications of Steel Coil Protection Board
- Galvanized steel packaging board offers strong rust resistance and excellent impact resistance. It suits short- and medium-distance transport of cold-rolled and hot-rolled coils.
- Stainless steel packaging board provides high corrosion resistance. It protects premium stainless steel coils and export-grade automotive steel sheets.
- Aluminum alloy packaging board is lightweight and corrosion-resistant. It applies to aerospace steel coils and precision alloy materials.
Multi-layer composite packaging protection steps
To protect steel coils from corrosion during long-term storage or sea transport, steel plants use a multilayer composite packaging system. The structure includes the following layers:
Inner Layer Protection (Sealing and Isolation)
VCI Paper slowly releases rust inhibitors such as nitrite derivatives. It creates a protective atmosphere that blocks electrochemical reactions on metal surfaces.
Sealing tape with strong waterproof adhesion, such as PET-based tape, completely wraps the edges and prevents moisture intrusion.
Middle Layer Protection (Cushioning and Moisture Resistance)
PE stretch film tightly wraps the coil. It adds a moisture barrier and reduces friction damage during transport.
Cardboard lining fits the coil’s end face and avoids edge abrasion.
Reinforced corner protectors made of hard cardboard shield the four corners and resist deformation during lifting.
Outer Layer Protection (Impact and Waterproofing)
Galvanized steel sheet wrapping provides mechanical protection and withstands forklift handling or stacking pressure.
Steel strapping with tensile strength above 900MPa secures the entire structure firmly.
Conclusion
After steel coil products receive wrapping with protective boards, the products look neat and clean while also improving protection performance.
This enhanced protection includes moisture resistance, dust prevention, rust resistance, anti-aging capability, and impact protection, thereby extending the quality guarantee period during storage and transportation.
Steel Coil Protection （Steel Coil Protection Material） is not just a simple logistics process. It directly influences end-user satisfaction with steel products.
