AZ70 Coating Aluzinc Coil Golden AFP Galvalume Steel For Stone Coated Roof Tile A792M DX51D Regular Minimum Spangle
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.
1. High Strength: SGC570 is a high-tensile steel with a minimum yield strength of 570 MPa. This makes it suitable for applications requiring high structural integrity.
2. Formability: Despite its high strength, SGC570 maintains good formability, allowing it to be shaped into various profiles without cracking.
3. Corrosion Resistance: The aluminum-zinc coating provides excellent protection against corrosion, significantly extending the material's lifespan.
4. Heat Reflectivity: The coating also offers high reflectivity of heat, which can contribute to thermal efficiency in buildings.
Colour Coated Coil Usage
Colour coated coils offer a range of benefits including light weight, aesthetic appeal, and excellent anti-corrosion properties. They can be directly processed and are available in a variety of colours such as grey, white, sea blue, and brick red. These attributes make them suitable for a wide range of applications, including:
- Advertising: Used for billboards, signage, and display panels.
- Construction: Ideal for roofing, wall cladding, and structural panels in residential and commercial buildings.
- Home Appliance Industry: Used for the exterior panels of refrigerators, washing machines, and other appliances.
- Electrical Appliances Industry: Employed in the manufacturing of components for various electrical devices.
- Furniture Industry: Applied in the creation of metal furniture, offering a variety of colours and finishes.
- Transport Industry: Utilized in the automotive sector for vehicle bodies and parts.
