Is Galvalume superior to galvanized in all conditions

NEWS / wanzhigroup

The corrosion resistance of aluminum zinc coated coils (such as 55% aluminum zinc alloy, commonly known as Galvalume) is superior to that of ordinary galvanized coils (pure zinc coating) in most environments, but not all environments are suitable. Its advantages and limitations need to be analyzed in conjunction with specific corrosion conditions. Comparison of Corrosion Resistance with Galvalume vs Galvanized Environment Type Aluminum Zinc (AZ/GL) Galvanized (GI) performance Conclusion Neutral/alkaline atmosphere The oxide film of aluminum (Al ₂ O3) is dense and stable, with excellent corrosion resistance Sacrificial protection of zinc layer, but faster corrosion rate AZ is significantly better than GI Weak acid environment (pH 4-6) Aluminum film partial

PVDF vs SMP Coating: Which is Better for Roofing?

NEWS / wanzhigroup

PVDF vs SMP Coated Roof Definition PVDF Coated Steel PVDF (polyvinylidene fluoride) coating is a high-performance, pre-painted steel sheet containing at least 70% PVDF resin. High-temperature baking forms a dense protective layer, specifically designed for roofs used in extreme climates. SMP Coated Steel SMP (silicone modified polyester) coating is a modified polyester pre-painted steel sheet containing silicone resin. It offers a lower cost and is suitable for industrial/agricultural roofs used in short- to medium-term applications. PVDF vs SMP Coating Performance Comparison Features PVDF Coating SMP Coating Weather Resistance Extreme (25+ years, ΔE
