Narrow Gabion Cages are compact, double-sided gabion wall systems designed for modern architecture and landscaping. They are primarily used for high-end landscape partitioning and decoration in urban courtyards, commercial building facades, and confined spaces. Utilizing a high-strength welded wire mesh structure and a highly corrosion-resistant and rust-proof zinc-aluminum alloy (Galfan) coating, this product provides exceptional structural rigidity to prevent bulging on the narrow sides and ensures a decades-long, maintenance-free outdoor lifespan. As the original manufacturer, we support a full range of non-standard customization options, from thickness (starting from 150mm) and mesh size to special irregular shapes.

Product Advantages
High Space Utilization
With a width of only 0.3-0.5m, it can be installed in confined locations such as wall bases and drainage ditch edges. The self-weight after filling is approximately 0.5-1.0 tons/meter, providing sufficient anti-slip force.
Flexible Construction
When unloaded, a single gabion cage weighs ≤50kg, requiring only two people to move; no crane or heavy machinery is needed, making it suitable for narrow construction surfaces, and installation is more than 3 times faster than concrete pouring.
Replaces Concrete Formwork
Factory prefabricated, directly filled on-site, eliminating the need for formwork, rebar tying, and curing, shortening the construction period by more than 60% and reducing overall costs by 30%.
In conjunction with conventional gabion cages
Can be used as foot protection or capping for conventional gabion cages, forming a complete protective system and improving overall stability by approximately 20%.
Structural Components
Welded Wire Mesh Panels
Constructed from heavy-duty welded wire mesh with a rigid square or rectangular grid. This flat-panel structure ensures the narrow cage maintains perfect geometric lines, maximum flatness, and zero bulging under outward stone pressure.
Internal Tie Rods / Stiffeners
Cross-bracing steel hooks inserted inside the cage to connect the front and back panels. These are crucial for slim designs to lock the two mesh walls together and completely prevent central distortion after filling.
Partitions (Diaphragms)
Internal vertical mesh panels secured at regular intervals (typically every 1 meter) along longer baskets. They divide the cage into balanced cells to enhance overall structural integrity and prevent stone migration.
Rock Filler & Assembly Components
High-density, corrosion-resistant stone is used as filler material (granite, basalt, colored quartz, etc. with a particle size of 60 mm to 120 mm). The particle size is larger than that of the mesh material. Spiral strap fasteners and high-tensile C-rings are used to quickly and securely align the edges during on-site assembly.
Applications
Drainage Ditch Foot Protection: Placed close to the ditch wall to prevent collapse.
Bridge Abutment and Riverbank Junction: Fills narrow gaps to prevent erosion by water flow.
Pipe or Cable Protection: Laid along the pipeline route, covered with gravel to prevent external damage.
Landscape Step Edges: Serves as step retaining strips, filled with colored pebbles, combining function and decoration.
Narrow Gabions and Rock Crevices Filling: Used to fill narrow gaps and lock loose rocks when controlling rockfalls or shallow landslides.
Quality Control
Raw Material Inspection
Each batch of steel wire undergoes spectral analysis and coating thickness measurement upon arrival at the factory. Batches with zinc coatings below 245g/㎡ are returned.
In-Process Sampling Inspection
Width and edge wire diameter are randomly sampled every 2 hours on the weaving or welding line. Machines are stopped and adjusted if deviations are found.
Finished Product Deformation Resistance Test
Narrow cages are randomly selected from each batch for simulated filling. Width expansion rate is measured to be ≤2% to prevent bulging on-site.
Factory Packaging Protection
Long cages are secured with wooden frames or special pallets, bundled with steel straps, and subjected to drop tests to ensure no deformation during transport.
FAQ
Q: What are the main differences between Narrow Gabion Baskets and regular gabion boxes?
A: Significantly narrower width, suitable for confined spaces; thicker edge wires and denser partitions prevent twisting of slender boxes.
Q: Can they be used at the beach?
A: Available in Galfan or 316L stainless steel, these baskets offer stability in the width direction and are less prone to tipping over due to waves.
Q: Are Narrow Gabion Baskets easily deformed during transport? How can this be prevented through packaging?
A: Narrow Gabion Baskets have a large length-to-width ratio, which may cause them to twist during transport. We use internal wooden strips or a steel frame for temporary reinforcement, and when stacking multiple baskets, corrugated cardboard is placed between them, and they are secured with steel straps in a cross shape.
