I. Introduction to Galvanized Steel
Galvanized steel is a new type of corrosion-resistant steel sheet. It is formed by solidifying 55% aluminum, 43.4% zinc, and 1.6% silicon at 600°C. Its structure consists of a dense quaternary crystal structure of aluminum, iron, silicon, and zinc, creating a strong and effective corrosion barrier. Due to its excellent corrosion resistance and long lifespan, it is widely used in construction, home appliances, transportation, and other fields.

II. Types of Galvanized Steel
Common types of galvanized steel on the market include AZ50, AZ70, AZ100, AZ150, AZ180, and AZ200. These types differ primarily in the coating weight, that is, the aluminum-zinc alloy content per square meter. For example, AZ100 indicates a coating weight of 100 grams per square meter.

III. Characteristics and Applications of Each Type
1. AZ50: This type of galvanized steel has a thinner coating and is suitable for applications where corrosion resistance is less critical. Due to its lower cost, it is often used in temporary or low-cost construction projects.

2. AZ70: Compared to AZ50, AZ70 has a thicker coating and improved corrosion resistance. It is commonly used in building materials such as roofing and siding, as well as in some home appliances requiring moderate corrosion resistance.

3. AZ100 to AZ150: These types of galvanized steel offer a good balance between corrosion resistance and cost. They are widely used in various building structures and industrial equipment requiring long-term corrosion protection, such as factories, warehouses, and bridges.

4. AZ180 and AZ200: These types of galvanized steel have the thickest coating and the highest corrosion resistance. They are suitable for use in extremely harsh environments, such as coastal areas and chemical industrial zones, ensuring the long-term operation of buildings and equipment without the effects of corrosion.
