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.

Tip

When purchasing metal materials, consumers should pay attention not only to price and performance, but also to brand and reputation. Choosing a well-known manufacturer can guarantee quality and after-sales service.

3. Why is Galvalume More Expensive Than Galvanized?

Galvalume steel coils are more expensive than standard galvanized steel coils due to two main factors: first, the production process. Galvalume steel coils require a special coating treatment, which results in higher manufacturing costs. Second, product performance. The aluminum content in galvalume steel coils provides superior corrosion resistance and aesthetics. In contrast, the production process for GI coils is relatively simple and cost-effective. The Aluminium in GL coils reacts with oxygen to form a dense oxide layer, a self-protective mechanism that contributes to their superior durability.

What are the influencing factors?

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

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 AZ50 galvalume steel coils.
