Comprehensive Guide to Galvanized Productions: Types, Features, and Applications

Galvanized productions are essential in industries like construction, automotive, and household appliances due to their corrosion resistance, durability, and aesthetic appeal. Choosing the right type of galvanized product ensures long-lasting performance and optimal results. This guide explains the main types of galvanized productions and their key applications.

1. Hot-Dip Pure Zinc Products (GI)

Hot-dip pure zinc products, also known as GI, are prized for their smooth surface finish, excellent corrosion resistance, and easy processing. Traditionally, these products displayed "zinc flowers" due to impurities such as lead in the zinc bath. Modern refining techniques allow manufacturers to produce almost flower-free surfaces, meeting the strict coating requirements of the automotive industry.

For architectural or decorative applications where zinc flowers are desired, trace elements like lead or antimony can be added to create larger, visually appealing patterns.

Key Benefits of GI Products:

· Attractive surface appearance

· Strong corrosion resistance

· Good workability and processing

2. Alloyed Galvanized Products (GA)

Alloyed galvanized productions (GA) offer superior paint adhesion and excellent corrosion protection after coating. They also provide excellent welding performance, making them ideal for coated applications. However, GA products have a gray surface and are not recommended for bare usage, as the zinc-iron alloy contains 7-15% iron, which may develop a faint red rust without coating.

Common applications include automotive panels and refrigerator sides, where GA products can even be powder-coated without pre-treatment.

Key Advantages:

· Excellent paint adhesion

· Durable and corrosion-resistant after coating

· High weldability

3. Aluminum-Zinc Galvanized Products

Aluminum-zinc galvanized productions are widely used for their exceptional corrosion resistance and visually appealing surface, with zinc flowers resembling decorative fish scales. They are 2–6 times more corrosion-resistant than standard hot-dip galvanized products and maintain stability at high temperatures up to 300°C, with short-term tolerance up to 700°C.

These properties make aluminum-zinc products ideal for construction, household appliances, and industrial equipment, providing both durability and aesthetic appeal.

Key Benefits:

· Outstanding corrosion resistance

· High-temperature stability

· Attractive surface appearance for bare use
