The galvalume steel coil is an important alloy material in our daily life. It is widely used in Civil and commercial buildings manufacturing corrugated sheets, home appliances, etc. The appearance of galvalume steel coils is particular. It is smooth, flat, and has beautiful spangles. Excellent corrosion resistance because of the special cladding structure.
Galvalume steel coil is composed of a zinc-aluminum alloy structure, of 55% aluminum, 43% zinc, and 2% silicon solidified at 600 degrees high temperature. The excellent corrosion resistance of galvalume steel coil is mainly due to the protective function of aluminum. If the zinc is worn, the aluminum forms a layer of alumina, preventing further corrosion of the steel coil.

The service life of GL coils can reach 25 years. It has good heat resistance, which can be used in high-temperature environments at 315°C. The advantages of galvalume coils are as below:
1. Anticorrosion: Galvalume steel coils have powerful corrosion resistance. The working life may be up to 25 years at normal use, 3-6 times longer than galvanized coils.
2. Heat reflectivity: Heat-shielding performance, suitable for roofing sheets.
3. Recoatability Auzinc coil can maintain excellent adhesion with the paint film and can be directly painted or sprayed powder.
4. Machinability: Aluzinc coil has outstanding processing functions, and can be stamping, cutting, welding, and so on.
Galvalume coils and galvanized coils are all metal materials, but they have some differences in character and applications.
a. Appearance: Galvanized steel coil is grey or milky white, and galvalume coils are usually silver or golden.
b. Corrosion resistance: Galvalume steel coil is more corrosion resistant than galvanized coils. So galvalume coil has a longer service life.
c. Prevent fingerprints: The surface of the galvalume coil is covered with a layer of stainless steel film, which can better resist fingerprints and maintain cleanliness.
d. Price: The manufacturing cost of alu-zinc coil is higher than that of galvanized coils, so the price is usually higher.
Galvalume steel coil and galvanized steel coil are essential metal materials, they have a wide range of applications in different fields. When choosing, you can make a balance according to your actual needs and budget.
If you pay attention to appearance and corrosion resistance, then GL coil will be a very good choice. Although the price is relatively high, it has a longer service life and a more beautiful appearance. Especially in the field of construction and home furnishing, the wide application of galvalume steel coil makes it a favorite material for the public.
And if you focus on price and practicality, then galvanized coils are a good choice. Especially in some relatively simple industrial applications, the corrosion resistance of the galvanized coil is enough to meet the demand, and the price is relatively low. At the same time, in some projects with low appearance requirements, galvanized sheets can also play their advantages.
As a consumer, when you choose and buy metal materials, in addition to focusing on price and performance, you should also pay attention to brand and reputation. Choosing a well-known manufacturer can guarantee quality and after-sales service, so as to better meet our needs.
The price of galvalume steel coils is more expensive than galvanized steel coils. In the production process, alu-zinc coils need galvalume coating treatment, therefore, the manufacturing cost is high. Meanwhile, galvalume steel coil has a beautiful appearance, so the price is expensive. However, the manufacturing process of galvanized steel coil is not complex, the price is low relatively. Galvalume has the element of aluminum. Aluminium has a density lower than those of other common metals; about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
