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.
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.
Why Aluzinc over Galvanised Steel?
1. Superior Corrosion Resistance:
- Composition:
Aluzinc steel is coated with an alloy composed of 55% aluminium, 43.4% zinc, and 1.6% silicon. This composition provides significantly better corrosion resistance compared to galvanised steel, which is coated with pure zinc.
- Durability:
The aluminium in the coating forms a protective barrier that prevents corrosive substances from reaching the steel core, extending the life of the roof tiles. This is particularly important in coastal and industrial environments where corrosion can be a significant issue.
2. Improved Thermal Reflectivity:
- Energy Efficiency:
The high aluminium content in Aluzinc steel gives it excellent thermal reflectivity, which can help reduce heat absorption in buildings. This leads to improved energy efficiency and can lower cooling costs, a valuable feature for roofing materials.
3. Enhanced Aesthetic Appeal:
- Surface Appearance:
Aluzinc steel has a smooth, shiny surface that is aesthetically pleasing and can enhance the visual appeal of stone-coated roof tiles. The attractive finish of Aluzinc steel can be maintained for a longer period compared to galvanised steel, which tends to dull and oxidise over time.
4. Longer Service Life:
- Extended Longevity:
Stone-coated metal roof tiles made from Aluzinc steel typically have a longer service life due to the enhanced protective properties of the coating. This results in lower maintenance and replacement costs over the lifespan of the roof.
