Classified by galvanized material
| Type | Zinc Coating Thickness | Features Typical Applications |
|---|---|---|
| Electro-galvanized | 7–15 g/m² | Poor corrosion resistance; suitable only for temporary works or dry environments |
| Standard Hot-dip Galvanized | 35–55 g/m² | Low cost; used for general freshwater bank protection |
| Heavy Hot-dip Galvanized | 215–265 g/m² | Good corrosion resistance; standard choice for river training, levee, and dike projects |
| Galfan (Zinc-Aluminum Alloy) | 215–500 g/m² + 5% Al (or 10% Al) | 3× better corrosion resistance than pure zinc; ideal for marine atmospheres, chemical plants, and other aggressive environments |
✅ Optional upgrade: All of the above can be over-sleeved with PVC/PE in green, gray, or black to enhance aesthetics and weather resistance.
Galfan (Zinc-Aluminum Alloy) double-twisted gabion
Structural style :
- Mesh size (cm): 6 × 8, 8 × 10, 10 × 12, 12 × 15, 16 × 18, 20 × 22, etc
- Wire diameter (mm)
- Mesh wire 2.0-4.0;
- The edge silk is 0.5-1.0 thicker than the mesh silk;
- Binding wire 2.0-2.2.
- Corresponding relationship: Small hole 6 × 8 with 2.0/2.7 mm mesh wire, commonly used in anti-collision grooves or reno mattress; Large hole 16 × 18 with 3.0/4.0 mm mesh wire, commonly used in gabion retaining walls or reinforced retaining walls.

Performance advantages and applications
- Performance:
- Flexibility: can withstand 10% uneven settlement without overall collapse;
- Permeable: With a porosity of 15-30%, it can reduce pore water pressure without the need for a filter layer;
- Impact resistance: Tested to withstand a flow velocity of 5 m/s and a wave resistance height of 3 m;River training
- Ecology: Natural soil accumulates between rocks, and herbs can grow in 3-6 months. After 1-2 years, the root system connects the rocks with the soil, increasing shear strength by more than 40%;
- Fast construction: manual on-site stone installation, no need for water and electricity, daily person can lay 15-20 square meters;
- Economy: With the same volume of retaining walls, it saves 20-40% of direct costs compared to concrete, and does not require expansion joints or drainage holes.
- Scope of application:
- Places such as rivers, dams, roadbeds, tunnels, etc. that are often subject to water erosion and dredging;
- Places where the strength of the protective layer needs to be increased, such as revetments, breakwaters, and flood walls;
- Protection projects for slopes, garbage dumps, beaches, coasts, and other areas.
