Main Applications
Corrosion Resistance
Galvanizing is a cost-effective and widely used method for rust prevention. Approximately half of the world’s zinc production is used for this process. Zinc not only forms a dense protective layer on the steel surface but also provides cathodic protection. Even when the zinc coating is damaged, it continues to prevent corrosion of iron-based materials through this protective mechanism.
Good Cold Bending and Welding Performance
Low carbon steel is primarily used, offering excellent cold bending and welding performance, as well as a certain degree of stamping capability.
High Reflectivity
The material has a high level of reflectivity, making it an effective thermal barrier.
Strong Coating Toughness
The zinc coating forms a unique metallurgical structure that can withstand mechanical damage during transportation and use.
Protective Wrapping
High-quality, moisture-resistant materials such as plastic film or waterproof paper are used to prevent corrosion and surface damage.
Reinforcement with Steel Straps
Secure bundling ensures stability during handling and transportation.
Edge Protection
Durable edge protectors safeguard the corners and edges of steel products.
Custom Packaging Options
Palletized Packaging
Wooden or metal pallets are used for smaller steel sheets or coils, making handling easier and more efficient.
Container Packaging
Products are securely arranged in shipping containers to prevent shifting during transit.
Seaworthy Packaging
Includes rust-proof coatings, waterproof covers, and fumigated wooden crates, ideal for export shipments.
Steel Coils
Reinforced with steel rings and wrapped in plastic film or waterproof material to prevent rust.
Steel Sheets and Plates
Neatly stacked, wrapped in plastic film, and secured with steel bands. Optional frames provide extra protection.
Steel Pipes
Bundled together, covered with plastic film, and strapped with steel bands. End caps are used to protect pipe openings.
