Aluzinc vs Galvalume: Understanding the Differences.
When it comes to the construction industry, choosing the right materials is essential to ensure the longevity and durability of a structure. Two popular options for metal roofing and cladding are Aluzinc and Galvalume. While these two materials are often used interchangeably, there are some key differences between them that are important to understand before making a decision.
### What is Aluzinc?
Aluzinc is a type of steel that is coated with an alloy of zinc and aluminum. This coating provides protection against corrosion and rust, making it a popular choice for outdoor applications such as roofing and cladding. The alloy composition of Aluzinc typically consists of 55% aluminum, 43.4% zinc, and 1.6% silicon.
### What is Galvalume?
Galvalume, on the other hand, is a trademarked product by Bethlehem Steel Corporation that consists of a steel substrate coated with a mixture of zinc and aluminum. The composition of Galvalume is slightly different from Aluzinc, with a typical ratio of 45% zinc, 55% aluminum, and a small amount of silicon.
### Differences between Aluzinc and Galvalume.
**1. Composition:**.
The primary difference between Aluzinc and Galvalume lies in their alloy composition. While both materials contain zinc and aluminum, the ratios of these elements vary slightly. Aluzinc typically has a higher aluminum content compared to Galvalume, which may affect the performance and longevity of the coating.
**2. Performance:**.
In terms of performance, both Aluzinc and Galvalume are known for their excellent corrosion resistance and longevity. However, some studies suggest that Aluzinc may offer better protection in harsh environments due to its higher aluminum content. It is essential to consider the specific environmental conditions of your project when choosing between the two materials.
**3. Availability:**.
Galvalume is a trademarked product by Bethlehem Steel Corporation, while Aluzinc is a generic term used to describe steel coated with an alloy of zinc and aluminum. This means that Galvalume may be more widely recognized in the industry, but Aluzinc is a generic alternative that offers similar performance benefits.
### Conclusion.
In conclusion, while Aluzinc and Galvalume are both excellent choices for metal roofing and cladding, it is essential to understand the differences between them before making a decision. The composition, performance, and availability of these two materials can vary, so it is crucial to consider your specific requirements and environmental conditions when choosing between Aluzinc and Galvalume.
