AZM150 Aluzinc Steel Roll Coil 55% Aluminum 43.5% Zinc 1.5% Si Galvalume Steel Regular Spangle ASTM A792M CS-B
Overview
Aluminium-zinc coated steel, also known as Galvalume, is widely used in the home appliance industry due to its exceptional properties such as strong corrosion resistance, durability, and aesthetic appeal. The unique composition of aluminium, zinc, and silicon provides superior performance, making it a preferred material for various home appliances.
Aluzinc steel coil, also known as aluminium-zinc coated steel, is a type of steel product that features a coating made from an aluminium-zinc alloy. This coating typically consists of 55% aluminium, 43.4% zinc, and 1.6% silicon. The combination of these metals in the coating provides the steel with enhanced properties, making it suitable for various industrial and construction applications.
Advantages of Aluzinc Steel Coil
1. Superior Corrosion Resistance:
- The aluminium in the coating forms a tough, protective barrier that resists corrosion and oxidation. The zinc component provides galvanic protection, which helps prevent rust formation on exposed edges or scratches. This dual protection makes Aluzinc steel coils highly resistant to corrosion, especially in harsh or marine environments.
2. Excellent Heat Reflectivity:
- The high aluminium content in the coating reflects heat effectively, making Aluzinc steel coils ideal for roofing and siding applications. This property helps in maintaining cooler building interiors and contributes to energy efficiency.
3. Enhanced Durability:
- The combination of aluminium and zinc results in a coating that is more durable than traditional galvanization. Aluzinc steel coils have a longer service life, reducing the need for frequent replacements and maintenance.
4. Improved Aesthetic Appeal:
- The shiny, spangled finish of Aluzinc steel coils offers an attractive appearance. This makes them suitable for applications where aesthetics are important, such as architectural panels and decorative elements.
5. Good Formability and Weldability:
- Aluzinc steel coils retain good formability, allowing them to be easily shaped, bent, and processed without compromising the integrity of the coating. They can also be welded with proper techniques, making them versatile for various manufacturing processes.
6. High Temperature Resistance:
- Aluzinc coatings can withstand higher temperatures compared to traditional galvanized coatings. This makes Aluzinc steel coils suitable for applications exposed to high heat, such as chimneys, flues, and ovens.
7. Cost-Effective:
- Despite the higher initial cost compared to traditional galvanized steel, the extended lifespan and reduced maintenance requirements of Aluzinc steel coils provide cost savings over the long term. Their durability and resistance to harsh conditions can result in lower overall expenses for projects.
Material Requirements
The home appliance industry has specific requirements for aluminium-zinc coated steel to ensure it meets the necessary standards for performance and durability. These requirements include:
1. Composition:
- Typically, the coating consists of 55% aluminium, 43.4% zinc, and 1.6% silicon. This composition offers a balanced combination of protection and durability.
2. Thickness:
- The thickness of the aluminium-zinc coating can vary depending on the application, but it generally ranges from 30 to 150 grams per square meter.
3. Base Steel:
- The base steel used is usually low-carbon steel, which provides a good balance of strength and formability.

Storage Guidelines
1. Indoor Storage:
- Warehouse Environment: Store the coils in a dry, well-ventilated warehouse to protect them from rain and high humidity.
- Elevation: Place the coils on elevated platforms or pallets to keep them off the ground and prevent contact with water.
- Temperature and Humidity Control: Maintain a stable temperature and humidity level inside the warehouse to prevent condensation on the coils.
2. Outdoor Storage:
- Covering: If indoor storage is not possible, cover the coils with waterproof tarpaulins or plastic sheets. Ensure that the covers are tightly secured to prevent water ingress.
- Proper Ventilation: Leave some space for air circulation under the covers to avoid moisture buildup and condensation.
- Inclination: Store the coils at a slight incline to facilitate water runoff and prevent pooling on the surface.
