The following types of galvanized wire are suitable for making gabion mesh:

Hot-dip galvanized wire: This type of wire undergoes a hot-dip galvanizing process, resulting in a thick and uniform zinc coating that offers excellent corrosion resistance, making it suitable for various environmental conditions.
Galfan (zinc-aluminum alloy) galvanized wire: It provides superior corrosion resistance compared to regular hot-dip galvanized wire and has a longer service life, making it ideal for gabion mesh that will be exposed to harsh environments for extended periods.
Zinc-5% aluminum-mixed rare earth alloy coated wire: This wire has strong corrosion resistance and good adhesion, ensuring stability even in challenging conditions.

When choosing galvanized wire for gabion mesh, the following factors should be considered:

Wire diameter: Generally, it ranges from 2.0 to 4.0 mm, depending on the application and load-bearing requirements of the gabion mesh.
Tensile strength: Usually, it should be within the range of 350 to 550 MPa to guarantee the structural strength of the gabion mesh.
Flexibility: It should have a certain degree of flexibility to facilitate weaving and installation, and be able to deform to some extent without breaking when subjected to forces.
Quality of the zinc coating: The thickness and uniformity of the zinc coating should comply with relevant standards to ensure effective anti-corrosion.
Environmental requirements: It should meet environmental standards with minimal impact on the environment.

The service life of a Gabion net is closely related to the quality of the zinc layer.

A better quality zinc layer, including aspects such as its thickness, uniformity, adhesion, and purity, leads to a stronger anti-corrosion ability of the Gabion net. A good zinc layer can effectively prevent water, oxygen, and other corrosive substances from the external environment from reacting with the steel wire substrate, thus delaying the corrosion and damage rate of the steel wire.

A thicker and more uniform zinc layer can continuously provide protection during long-term use. Even if the zinc layer is partially damaged to a certain extent, it can still protect the internal steel wire and extend the overall service life of the Gabion net.

Conversely, if the quality of the zinc layer is poor, such as insufficient thickness, non-uniformity, or poor adhesion, problems such as local corrosion and peeling are prone to occur, causing the steel wire substrate to be exposed to the external environment more quickly and accelerating the corrosion process, thereby significantly shortening the service life of the Gabion net.

In summary, the quality of the zinc layer is one of the key factors affecting the service life of the Gabion net. A high-quality zinc layer helps to significantly extend the service life of the Gabion net.
