Aluminum-Zinc-Magnesium Alloy Coating（ZAM）
ZAM cable bridge Process Overview: Advanced metallic coating combining zinc (94%), aluminum (4 .5%),
and magnesium (1.5%) applied through continuous hot-dip process, offering superior
corrosion protection.
ZAM cable bracket Process Flow:
1. Steel Preparation: Surface cleaning and pre-treatment
2. Continuous Hot-Dip: Immersion in molten ZAM alloy bath
3. Controlled Cooling: Precise temperature control for optimal microstructure
4. Skin Pass: Light rolling for surface finish
5. Quality Control: Coating weight and adhesion testing
ZAM cable tray Advantages:
· Superior Corrosion Resistance: 3-5 times better than conventional galvanizing
· Self-Healing Properties: Magnesium provides enhanced cathodic protection
· Excellent Cut-Edge Protection: Outstanding performance at sheared edges
· Thermal Stability: Maintains properties at elevated temperatures
· Formability: Excellent forming characteristics without coating damage
· Environmental Performance: Consistent protection across diverse climates
ZAM cable bridge Disadvantages:
· Premium Cost: 15-30% higher cost than standard galvanizing
· Limited Availability: Fewer suppliers and processing facilities
· Specialized Application: Requires specific expertise and equipment
· Newer Technology: Less long-term field performance data available
ZAM cable bracket Applications & Service Life:
· Coastal and marine environments: 40-80 years
· Industrial facilities with aggressive atmospheres: 35-60 years
· Chemical processing plants: 30-50 years
· Long-span outdoor installations: 40-70 years
· Automotive industry facilities: 25-45 years
· Applications requiring extended maintenance intervals: 35-65 years
· Extreme weather conditions (hurricanes, typhoons): 30-55 years.
