Gabion mesh processed with galvanized wire has the following specifications:

Gabion mesh processed with galvanized wire has the following specifications:

I. Mesh size specifications

Common mesh sizes include 60 x 80 millimeters, 80 x 100 millimeters, 100 x 120 millimeters, and more. Different mesh sizes are suitable for different engineering needs. Smaller mesh sizes can better prevent the loss of small particle fillers, while larger mesh sizes may be more suitable for some occasions with higher permeability requirements.

II. Wire diameter requirements

Side wire: Generally, the side wire has a thicker diameter, usually between 2.7 millimeters and 3.4 millimeters. The side wire plays a role in strengthening the structural strength of the edge of the gabion mesh.
Mesh wire: The diameter of the mesh wire is usually between 2.0 millimeters and 2.7 millimeters. The thickness of the mesh wire directly affects the overall strength and durability of the gabion mesh.

III. Material requirements

Galvanized wire: High-quality low-carbon steel wire is used for galvanizing treatment. The thickness of the galvanized layer is generally required to be more than 245 grams per square meter to ensure good corrosion resistance in various environments.
Zinc-aluminum alloy wire: In some occasions with higher corrosion resistance requirements, zinc-aluminum alloy wire can be used to process gabion mesh, and its corrosion resistance is more superior. The aluminum content in zinc-aluminum alloy wire is usually between 5% and 10%.

IV. Size specifications

Length: The length of the gabion mesh can be customized according to the actual needs of the project. Common lengths are 2 meters, 3 meters, 4 meters, and so on.
Width: The width is generally between 1 meter and 2 meters, and can also be adjusted according to specific needs.
Height: The height is usually between 0.5 meters and 1 meter. Gabion meshes of different heights can be used for different slope protection and bank protection projects.

V. Other requirements

Twisting method: The side wire and mesh wire of the gabion mesh are twisted in a triple twist or double twist manner to ensure that the mesh structure is firm and not easily dispersed.
Tensile strength: The tensile strength of the gabion mesh should meet the requirements of relevant national standards, generally not less than 350 megapascals.
Elongation: The elongation should not be too high or too low, usually between 10% and 15%, to ensure that the gabion mesh has a certain deformation ability without being damaged when subjected to external forces.

The advantages of gabion mesh made of galvanized wire are as follows:

1. Excellent corrosion resistance

The galvanized treatment forms a dense zinc layer on the surface of the wire, effectively blocking the contact of air, water and other corrosive substances with the wire. This greatly delays the corrosion rate of the wire. In harsh environments such as wet, rainy and seawater areas, galvanized wire gabion mesh can still maintain stability for a long time.
Compared with ordinary steel wire, galvanized wire has a longer service life, reducing the cost and workload of frequently replacing gabion mesh due to corrosion.

2. High strength and toughness

Galvanized wire itself has high strength and can withstand large tensile and compressive forces. After the gabion mesh is filled with stones and other fillers, it can effectively resist the impact of water flow, the beating of waves and the pressure of soil, ensuring the stability of slope protection and bank protection projects.
At the same time, galvanized wire also has certain toughness. When subjected to external forces, it can deform to a certain extent without breaking. This enables the gabion mesh to adapt to changes in terrain and uneven settlement, avoiding damage due to excessive local stress.

3. Ecological and environmental protection

Gabion mesh has good water permeability and air permeability, which can promote the exchange of substances between water bodies and soil, providing habitats and breeding places for aquatic organisms and helping maintain ecological balance.
Galvanized wire does not release harmful substances and does not pollute the water body and soil environment, meeting the requirements of modern ecological and environmental protection projects.

4. Convenient construction

Gabion mesh adopts modular design, which is very convenient for transportation and installation. The gabion mesh can be processed into mesh sheets of a certain size in the factory and then transported to the construction site for assembly.
The connection method of galvanized wire gabion mesh is simple, generally using spiral binding or special connectors. It does not require complex construction equipment and technology, which can greatly shorten the construction period and reduce construction costs.

5. Aesthetic and durable

The appearance of galvanized wire gabion mesh is silver, which has certain aesthetics. It can blend with the surrounding natural environment and will not appear as rigid and uncoordinated as traditional concrete slope protection.
Due to its good corrosion resistance and high strength, gabion mesh can maintain a stable structure and appearance for a long time without frequent maintenance and repair.
