Usage

I. Construction and Infrastructure

1. Building Structures

◦ Applications: Roofs, walls, ceiling joists, steel structure factories. Particularly effective in harsh climates or high-salt environments, reducing maintenance costs.

◦ Case Study: Shanghai Airport Terminal’s exterior wall panels using Zn-Al-Mg coils achieved 10 years of maintenance-free performance.

2. Infrastructure

◦ Highway Guardrails, Bridges, Urban Utility Tunnels: Enhanced lifespan due to superior corrosion resistance (10–20× traditional galvanized steel) and wind resistance.

II. Energy and Photovoltaics

1. Solar Mounting Systems and Frames

◦ Coastal/Desert Environments: Zn-Al-Mg’s corrosion resistance is 4–5× higher than traditional galvanized steel, with self-healing capabilities at cut edges.

◦ Technical Note: Mg²⁺ ions react with atmospheric O₂/CO₂ to form protective layers (e.g., Mg(OH)₂), sealing micro-cracks.

2. Power Facilities

◦ Equipment: High/low-voltage switchgear, transformer housings, capacitors. Suitable for high-temperature and chemically corrosive environments.

III. Transportation

1. Automotive Manufacturing

◦ Body Panels, Chassis, Containers: Improved weather resistance and safety; lightweight design reduces energy consumption.

◦ Material Advantage: Surface hardness≥2× conventional galvanized steel, suitable for stamping and welding.

2. Railway Vehicles

◦ Exterior Panels, Doors: Extended service life through corrosion resistance and structural integrity.

IV. Appliances and Industrial Equipment

1. Household Appliances

◦ Refrigerators, Washing Machines, AC Units: Utilizes corrosion resistance and lightweight properties (e.g., 30–50% cost savings vs. stainless steel).

2. Industrial Machinery

◦ Pipelines, Anti-corrosion Equipment: Resists corrosive media (e.g., oil well pump rods).

V. Agriculture and Livestock

• Light Steel Structures:

◦ Greenhouses, Barn Roofs, Fencing: Adapts to humid and chemically aggressive environments.

◦ Cold-formed Profiles: C/Z-shaped steel supports agricultural infrastructure.

VI. Other Specialized Applications

• Electronics Enclosures: Protects internal components from environmental damage.

• Solar Energy Mounting: Ensures stability and long-term operation in extreme conditions.

Key Performance Advantages Supporting Applications:核心优势

1. Corrosion Resistance:

◦ Self-healing via Mg/Al oxidation at cut edges, forming dense protective layers (e.g., Mg₅(CO₃)₄(OH)₂·4H₂O).

2. Processing Performance:

◦ Excellent stamping, bending, and welding properties (friction coefficient reduced by 15% vs. pure Zn).

3. Cost Efficiency:

◦ 30–50% cheaper than stainless steel, with lower lifecycle costs.

4. Sustainability:

◦ Chromium-free, recyclable, and compliant with RoHS/REACH standards
