PVC Coated Woven Wire Gabion Box for River Bank and Channel Lining Protection
Introduction
Our PVC coated woven wire gabion box is a premier engineering solution specifically designed for high-velocity water flows, severe soil erosion, and harsh corrosive environments. Manufactured from high-quality double-twisted hexagonal steel wire mesh, these gabions are heavily galvanized and further coated with a resilient PVC (Polyvinyl Chloride) layer.
Whether you are reinforcing a river bank, constructing channel linings, or securing bridge abutments, our gabion baskets provide a flexible, permeable, and monolithic structure that blends seamlessly with the natural environment over time.
Why Choose PVC Coated Woven Wire Gabions?
1. Superior Corrosion & UV Resistance
The heavy zinc coating (Galfan option available) combined with the external PVC sleeve provides double-layer protection. It perfectly resists acidic soils, saltwater, and long-term UV exposure, extending the structure's service life up to 50+ years.
2. Excellent Flexibility & Structural Integrity
The double-twisted hexagonal weave ensures that the mesh will not unravel even if a wire is cut or broken. The inherent flexibility allows the gabion boxes to settle and deform naturally with the ground movement without structural failure.
3. Permeability for Natural Drainage
Unlike rigid concrete walls, gabion structures are highly permeable. They eliminate hydrostatic pressure buildup behind the wall while promoting natural vegetation growth, restoring the local riparian ecology.

Professional Application Scenarios
Our woven wire gabion boxes are widely specified by civil engineers and environmental agencies for:
-
River Bank Stabilization & Training: Preventing bank collapse and managing high-energy river flows.
-
Channel Lining & Culvert Protection: Protecting canal beds and banks from scour and erosion.
-
Retaining Wall Structures: Gravity retaining walls for slopes, highways, and railways.
-
Bridge Abutment & Pier Protection: Safeguarding critical infrastructure from water currents.
1.Assembly & Unfolding:Step 1.
Flat-packed gabions are unfolded on flat, hard ground. Erect all side panels, end panels, and diaphragms vertically to form a rectangular box.
2.Lacing & Securing:Step 2.
Secure the edges by lacing wire (or C-rings) spirally around the selvedge wires. Ensure all diaphragms are laced properly to prevent bulging.
3.Positioning & Alignment:Step 3.
Position the empty gabions in their designated locations. Join adjacent empty units along their contact edges to create a monolithic structure.
4.Rock Filling & Lidding:Step 4.
Fill the baskets with hard, durable, non-degradable stones (1.5 to 2 times the mesh size) in layers. Secure the lid tightly with lacing wire once fully filled.
Frequently Asked Questions (FAQ)
Q: What is the difference between woven gabions and welded gabions?
A: Woven gabions are made from double-twisted hexagonal wire mesh, offering extreme flexibility, which makes them ideal for hydraulic engineering (river banks, channels) where ground settling occurs. Welded gabions are rigid and mainly used for architectural landscaping and dry soil retaining walls.
Q: How long does a PVC coated gabion box last in water?
A: With heavy galvanization/Galfan and premium UV-stabilized PVC coating, our woven gabions can easily achieve a service life of 50 to 75 years, even in continuous underwater or coastal environments.
Q: Can you customize the gabion sizes and colors?
A: Yes. We offer fully customizable dimensions (length, width, height) and various PVC colors (typically dark green or grey to match natural river environments) to meet your specific project requirements.
