Differences Between Zinc-Aluminum-Magnesium Cable Trays and Hot-Dip Galvanized Cable Trays
1. Material Composition
Zn-Al-Mg Cable Trays:
Made from a zinc-based alloy coating enhanced with aluminum (Al) and magnesium (Mg). This advanced alloy technology creates a highly durable and corrosion-resistant protective layer.
Hot-Dip Galvanized Cable Trays:
Coated with pure zinc by immersing steel in molten zinc. The process forms a thick zinc layer to prevent rusting.
2. Corrosion Resistance
Zn-Al-Mg Cable Trays:
Superior corrosion resistance due to the synergistic effect of Al and Mg. Excels in harsh environments (e.g., humidity, acidic/alkaline exposure). The alloy coating has self-healing properties, forming stable protective layers even if scratched.
Hot-Dip Galvanized Cable Trays:
Offers good corrosion resistance for outdoor use but underperforms in extreme conditions like coastal or chemical-heavy areas.
3. Service Life
Zn-Al-Mg Cable Trays:
Extended lifespan in corrosive environments, outperforming HDG trays by 5–10 years. Ideal for long-term installations.
Hot-Dip Galvanized Cable Trays:
Suitable for general outdoor applications but degrades faster in high-salinity or acidic settings.
4. Surface Quality
Zn-Al-Mg Cable Trays:
Smoother surface with minimal burrs, ensuring a clean and professional appearance.
Hot-Dip Galvanized Cable Trays:
Rougher texture with visible zinc spangles (crystalline patterns) and occasional sharp edges.
5. Application Scenarios
Zn-Al-Mg Cable Trays:
Recommended for demanding environments:
Chemical plants
Coastal regions
Wastewater treatment facilities
Hot-Dip Galvanized Cable Trays:
Cost-effective for standard outdoor use:
Factories
Construction sites
Power infrastructure
Zn-Al-Mg cable trays provide unmatched corrosion resistance and durability for extreme conditions, while hot-dip galvanized trays remain a budget-friendly choice for general applications. Choose Zn-Al-Mg for longevity in harsh settings or HDG for reliable performance in standard environments.
