Galvalume Steel Coil

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. Wanzhi stocks a large number of regular-sized aluminum-zinc coated steels and accepts customization of length, width, thickness, and provides striping, perforation, painting, and embossing services. Please contact us for more information.

What Is Galvalume Steel Coil?

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.

Production Process

Benefits Of Galvalume 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.

Galvalume Steel Coils VS. Galvanized Coils

Galvalume coils and galvanized coils are both metal materials, but they have some differences in character and applications.

1. Differences

• Appearance: Galvanized steel coil is grey or milky white, and galvalume coils are usually silver or golden.
• Corrosion resistance: Galvalume steel coil is more corrosion resistant than galvanized coils. So, galvalume coil has a longer service life.
• 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.
• Price: The manufacturing cost of alu-zinc coil is higher than that of galvanized coils, so the price is usually higher.

2. Which Is Better?

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.

Focus on appearance and corrosion resistance

Then the 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.

Focus on price and practicality

Then, the 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 to their advantage.

 

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.

3. Why is Galvalume More Expensive Than Galvanized?

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.

Factors Affecting the Price of Galvalume Steel Coil

1.Market Demand

Market demand is one of the main factors affecting the price of galvalume steel coils. When market demand exceeds supply, prices will rise. When supply exceeds demand, prices will fall due to industry competition.

2. Raw Material Prices

The raw materials for the production of galvalume steel coils include iron, aluminum, zinc, silicon, etc. If the prices of these raw materials fluctuate, it will directly affect the cost of galvalume steel coils.

3. Production Costs

The production costs include labor, production equipment, warehousing, transportation and other costs. The increase in production costs will directly lead to an increase in the price of galvalume steel coils.

4. Currency Exchange Rates

In international trade, the exchange rate also has a certain impact on the price of galvalume steel coils. For example, if the seller’s currency appreciates, the price will rise when purchasing steel coils.

5. Specifications

The specifications of galvanized steel coils are different, and the prices are also different. For example, the prices of 0.3mm and 0.5mm are different. Different coatings have different prices. The price of AZ150 is higher than that of AZ30 galvanized steel coils.
