In the field of steel anti-corrosion coating, aluminized zinc coil and traditional galvanized coil have their own characteristics. Tangshan Hongsheng provides you with a detailed comparison of these two products to help you make the most informed choice.
Technical Advantages of Aluminum-Zinc Plated Coil
Aluminum-Zinc Plated Coil is coated with an alloy of 55% Aluminum, 43.5% Zinc, and 1.5% Silicon, which brings revolutionary performance enhancement.
Superior corrosion resistance: The combination of the passivation properties of aluminum and the sacrificial protection of zinc results in a 3-6 times higher corrosion resistance than ordinary galvanized coils, which performs particularly well in marine environments and acid rain areas.
Superior heat resistance: Aluminized zinc coatings can withstand continuous high temperatures up to 315°C, much higher than the 200°C limit for galvanized coils.
Better reflective properties: the high reflectivity of aluminum gives it excellent thermal insulation properties, which can effectively reduce energy consumption in buildings.
Comparative performance analysis
Simply put, aluminized zinc coils are superior in terms of corrosion resistance and longevity, and are particularly suitable for marine environments, with a service life of 25-30 years. On the other hand, galvanized coils are more advantageous in terms of processing performance and price, with a service life of 15-20 years, and are more suitable for use in inland areas.
Application Scenario Suggestions
Choose galvanized coil: inland areas, need frequent deep processing, higher requirements for cost control, short-term use projects.
Choose Aluminum Zinc Plated Coil: Marine climate, long-term outdoor exposure, high requirements for service life, projects that require thermal insulation performance.
