Generally speaking, the corrosion resistance of hot-dip galvanized wire is stronger.

During hot-dip galvanizing, a thick and firmly adhered zinc coating is formed, which provides better protection against corrosion. It can withstand more severe corrosive environments and has a longer service life in terms of corrosion resistance.

While electrogalvanized wire has a thinner zinc coating, which is relatively less resistant to corrosion, especially in harsh conditions, it may be more prone to corrosion and degradation.

However, specific corrosion resistance also depends on many factors such as the specific application environment and the quality of the galvanizing process.

When selecting between electric galvanized wire and hot galvanized wire according to specific needs, the following aspects can be considered:

Electric Galvanized Wire:

Appearance requirements: If there is a high demand for the surface smoothness and appearance finish of the wire, electric galvanized wire may be a better choice as it generally has a relatively smooth surface.
Less demanding environments: It is suitable for some indoor or relatively mild environments where corrosion resistance requirements are not extremely high.

Hot Galvanized Wire:

Corrosion resistance: If the application environment is harsh, with high humidity, exposure to chemicals, or outdoor use for a long time, hot galvanized wire offers superior corrosion resistance.
Durability: Needed in situations where long-term stability and reliability are crucial. For example, in outdoor fencing or structural applications.
Heavy-duty usage: When the wire will be subjected to greater mechanical stress or wear, hot galvanized wire is often more suitable due to its better coating integrity.

For example, for indoor decorative wire mesh, electric galvanized wire might suffice. But for a fence around a coastal area exposed to salt spray and harsh weather conditions, hot galvanized wire would be a more appropriate option to ensure longevity. Additionally, cost considerations and specific industry standards or regulations may also influence the selection.
