Galvalume Aluzinc Steel Coil Supplier in China

What is Galvalume Steel Coil ? 

     Galvalume steel coil is carbon steel sheet coated with aluminum-zinc alloy by a continuous hot dip process similar to the galvanizing process. Galvalume steel coil is a type of steel sheet that has been coated with an alloy of aluminum and zinc. The coating typically consists of about 55% aluminum, 43.4% zinc, and 1.6% silicon. . The alloy coating gives galvalume steel coil and sheets a smooth, plain finish.Galvalume sheet combines the excellent barrier corrosion protection of aluminum with the galvanic protection of zinc. Galvalume steel sheet is recommended when a high level of corrosion resstance is very important compared to traditional galvanized steel.

Benefits of Galvalume Steel Coil

Galvalume products, with their combination of aluminum and zinc, offer excellent corrosion resistance, high-temperature performance, and good formability. These products have a long service life, are environmentally friendly, and are widely used in applications that require durability, aesthetics, and performance. 

Galvalume products (aluminum-zinc coated steel) are steel sheets coated with an alloy of aluminum and zinc, typically produced through a hot-dip galvanizing process. These products combine the benefits of aluminum's corrosion resistance and zinc's anti-oxidation properties, making them ideal for a variety of applications. Below are the key features of Galvalume products:

1.Excellent Corrosion Resistance 

Galvalume products are known for their superior corrosion resistance, particularly in harsh environments such as high humidity, salt spray, and industrial pollution. This is due to:Aluminum: The aluminum coating naturally forms a protective oxide layer that prevents oxygen and moisture from reaching the base steel, significantly reducing rust and corrosion.Zinc: The zinc coating provides sacrificial protection to the underlying steel, meaning it corrodes first when the coating is damaged, protecting the base material from further corrosion.

2.Good High-Temperature Performance

Galvalume products can withstand relatively high temperatures. Aluminum has a better heat resistance compared to zinc, making Galvalume products more suitable for high-temperature applications. This is especially useful in roofing, ventilation systems, and other industries where heat resistance is crucial.

3.Good Surface Quality

Galvalume products have a smooth, uniform surface with a shiny, silvery appearance due to the aluminum-zinc alloy coating. The aesthetic quality of the surface is a key feature, making it ideal for applications where appearance matters, such as in architectural roofing and appliances.

4.Excellent Oxidation Resistance

The aluminum component in Galvalume products forms a dense oxide film on the surface, which acts as a barrier to oxygen and moisture, greatly enhancing oxidation resistance. This makes Galvalume products highly durable in environments where oxidation is a concern

5. Good Formability and Processability

Galvalume steel sheets offer good formability, which allows them to be easily processed through cold bending, deep drawing, and welding. While the coating is relatively hard compared to pure aluminum or galvanized coatings, it still provides superior formability and can be used in a wide range of manufacturing processes

6.Excellent Heat Reflectivity

The aluminum-zinc coating has high heat reflectivity, which helps to reflect sunlight and reduce heat absorption. This property makes Galvalume products particularly beneficial in roofing and building applications, as they help lower cooling costs by reducing the amount of heat absorbed by buildings.

7.Long Service Life

Due to their exceptional corrosion resistance and oxidation properties, Galvalume products typically have a longer service life than traditional galvanized steel. These products can last for decades without significant degradation in most environments, making them a cost-effective solution for long-term use.

8.Environmentally Friendly

The aluminum-zinc alloy coating is non-toxic and meets modern environmental standards. Compared to other coatings, Galvalume products have a minimal environmental impact and contribute to reducing waste because of their extended service life, which lowers the need for frequent replacements.

9.Lightweight

Despite the thicker coating, Galvalume products are lighter compared to some traditional protective coatings, making them easier to handle, transport, and install. This is especially advantageous in applications such as roofing and cladding, where large areas need to be covered with minimal weight.

10.Versatile Applications

Galvalume products are highly versatile and suitable for various environments and industries. Common applications include:Galvalume Construction Industry: Used in roofing, cladding, and facades due to their durability and aesthetic appeal.Appliance Manufacturing: Ideal for home appliances, including washing machines, refrigerators, and air conditioners.Automotive Industry: Used in some automotive components due to their corrosion resistance and lightweight properties.
