I.Materials and Their Lifespan

Material Types & Features

Hot-Dip Galvanized Steel Wire: This is the basic option. A zinc layer is applied to low-carbon steel wire through hot-dip galvanizing, usually about 80-100g/㎡ thick. It's good for resisting atmospheric corrosion and works well in dry environments without strong acids or alkalis. It's often used for mountain slope protection and basic roadbed reinforcement, lasting about 10-15 years.

Hot-Dip Galvanized PVC Coated Steel Wire: This builds on the galvanized wire by adding a layer of PVC or PE plastic, about 0.8-1.2mm thick, usually green or black. This keeps the rust protection from the zinc and adds better wear and chemical corrosion resistance. It's great for wet environments, river management, and coastal protection, lasting 20-30 years.

Galfan Steel Wire (Zinc-Aluminum Alloy Wire): This is the high-end choice, using a zinc-5% aluminum-mixed rare earth alloy coating, 100-150g/㎡ thick. It resists corrosion 3-5 times better than regular galvanized steel, especially against salt and marine environments. It's used for things like cross-sea bridge protection and high-salinity river management, lasting over 30 years.

Also, all these materials use low-carbon steel wire as the core, with a diameter of 2.0-4.0mm, making sure the wire is tough and strong enough to avoid breaking when filled with stones or hit by outside forces.

II.Sizes, Structure, and Applications

Sizes & Structure

Common Sizes: Length 2-4m × Width 1-2m × Height 0.5-1m (customizable), like 2m×1m×1m or 3m×2m×0.5m.

Best Uses: Smaller mesh boxes (2m×1m×0.5m) are often used for small slope protection and drainage ditch reinforcement. Larger mesh boxes (4m×2m×1m) are needed for riverbank protection and large roadbed reinforcement to improve overall stability.

Common Sizes: 60mm×80mm, 80mm×100mm, 100mm×120mm (Length × Width).

Matching Rule: The mesh opening should be smaller than 1/2 the size of the stones you're filling it with to stop them from falling out. For example, 60mm×80mm mesh works with stones over 120mm, and 100mm×120mm mesh works with stones over 200mm.

Mesh Wire Diameter: 2.0-3.0mm (for the woven mesh surface).

Edge Wire Diameter: 0.5-1.0mm thicker than the mesh wire (like 3.0-3.5mm if the mesh wire is 2.5mm) to make the edges stronger.
