Why are Mesh Size and Wire Diameter Important in Wire Gabions?

Gabions are earth-retaining structures made of woven wire mesh in the shape of a box and filled with stones. This material is widely used for construction purposes such as river embankments, cliff stabilization, erosion control, and modern garden and landscape design.
However, to ensure its strength and durability, two important factors to consider are the mesh size (the opening of the wire mesh) and the wire diameter.

1. Mesh Size Determines Stability of the Structure
Mesh size refers to the distance between the wire mesh holes in the gabion. Commonly used mesh sizes are:

Mesh Size	Common Usage
5 x 7 cm	Strong structure for small to medium-sized stones
8 x 10 cm	Commonly used for slopes, embankments, and erosion control
10 x 12 cm	For larger stones and high-pressure areas

The smaller the mesh size, the stronger and tighter the gabion is in resisting pressure because the stones are more stable and less likely to slip through the wire mesh.

Conclusion:
The choice of mesh size must be adjusted to the size of the filled stones and the structural durability requirements.

2. Wire Diameter Determines Tensile Strength
Wire gabions are produced in various diameters, such as:

Wire Diameter	Capacity & Applications
2.0 – 2.2 mm	Gardens, landscape decoration
2.7 – 3.0 mm	Light to medium erosion control
3.4 – 4.0 mm	Heavy construction such as river embankments, bridges, and steep slopes

The larger the wire diameter, the greater its tensile strength and resistance to water and soil pressure.

Important tip:
For river or cliff areas prone to landslides, a minimum diameter of 3.4 mm is recommended for safety and durability.

3. The Right Mesh & Diameter Combination
Selecting the best mesh and diameter should consider:

• Installation location (critical or light)
• Topography
• Water pressure & current levels
• Rock types & sizes

Examples of ideal combinations:

• Gardens and landscapes → 5x7 cm mesh, 2.0–2.2 mm diameter
• Cliffs or slopes → 8x10 cm mesh, 2.7–3.0 mm diameter
• River embankments/heavy projects → 10x12 cm mesh, 3.4–4.0 mm diameter

Conclusion
Mesh size and wire diameter significantly affect the strength and durability of wire gabions. Proper selection will increase structural safety and extend their lifespan, whether for heavy construction or decorative purposes.
