Galvanized / PVC Pipe Gabion Wall Cages Iron Wire Mesh Gabion Boxes Basket Prices In South Africa
Iron Wire Mesh Gabion Wall Cages is made of twisted hexagonal woven mesh. The metal wire used to make gabion baskets is made of soft tensile heavy galvanized steel, and PVC coating can also be used for additional corrosion protection when the application requires. The double twisting of the woven wire mesh provides structural integrity, strength and continuity by increasing the non-loosening effect of preventing any accidental damage from spreading. Fastening wires are used to assemble and interconnect empty units and to close and fix stone filling units. Once assembled, the basket will be filled with stones at the scene.
Gabion mattress is a woven gabion basket made of galvanized, twisted, hexagonal woven wire mesh. Baskets constructed from individual units are assembled, bundled together, and then filled with stones to form an integral structure. Gabion and Reynolds mattresses are used for retaining walls, sound barriers, canal lining, slope stability, dams and weirs. They are particularly effective in restoring the environment and promoting vegetation growth.

Gabion Wall Cages Characteristics:
(1) Economic. Just fill the stone into the gabion and seal it.
(2) Simple installation. No special technology needed.
(3) Weather proof under natural destroy, corrosion resistant.
(4) No collapse even under big scope of deforming.
(5) Sludge in the stones is good for plant growing. Mixed to form a integrity with the natural environment.
(6) Good permeation can prevent the damage by hydrostatics.
(7) Less transport freight. It can be folded together for transport and further installation.
Multifunction: gabion wall retaining wall cages can be stacked according to your requirements to create retaining walls with vertical, inclined or stepped facades. Meanwhile, woven gabion baskets can be installed in combination with various plants to enhance strength and a more pleasant appearance.
Long life: all our gabion retaining wall cages are heavily galvanized, and zinc-aluminum alloy is plated with optional polyvinyl chloride coating to resist corrosion and maximize its service life. Generally, our galfan gabion and PVC gabion can be used for up to 12 years according to different exposure conditions.
Gabion Cage Installation Process:
- 1. Ends,diaphragms,front and back panels are placed upright on the bottom section of wire mesh
- 2. Secure panels by screwing sprial binders through the mesh openings in adjacent panels
- 3. Stiffeners shall be placed across the corners, at 300mm from the corner. Providing a diagonal bracing,and crimped
- 4. Box gabion filled with graded stone by hand or with a shovel.
- 5. After filling,close the lid and secure with sprial binders at the diaphragms,ends,front and back.
- 6. When stacking tiers of the weled gabion,the lid of the lower tier may serve as base of the upper tier.Secure with sprial binders and add pre-formed stiffeners to exterior cells before filling with graded stones.
Gabion Cage Advantage:
Flexibility: Flexibility is an important benefit of any gabion structure. The double-twist hexagonal mesh construction permits it to tolerate differential settlement without fracture. This property is especially important when a structure is on unstable soil conditions or in areas where scour from wave action or currents can undermine the toe of the structure and cause structural settlement.
Durability: Gabions support plant growth which provides a live coating for the wire mesh and stones, adding to their durability. Generally, the wire mesh is needed for the first few years of the structure’s life; later the void between the stones is filled with soil, silt, and plant roots which act as a bonding agent for the stones.
Strength: Steel wire hexagonal mesh has strength and flexibility to withstand forces generated by water and earth masses, and the pervious nature of the gabion allows it to absorb and dissipate much of that energy. This is evident on coast protection installations where gabion structures remain effective long after a massive rigid structure fails. Additionally, the double twisted hexagonal mesh won’t unravel if cut.
Permeability: Gabion walls are previous to water and stabilize slopes by the combined action of draining and retaining, precluding the development of hydrostatic pressure behind the gabion wall. Drainage is accomplished by gravity, as well as evaporation as the porous structure permits air circulation through it. As plant growth develops within the structure, the process of transpiration assists in removing moisture from the backfill – a much more efficient system than weep holes in standard masonry walls.
Low cost: Gabion systems are more economical than rigid or semi-rigid structures for the following reasons:
• It requires little maintenance
• Its installations does not require skilled labor and stone fill is available on site or from nearby quarries,
• It requires little or no foundation preparation, as the surface needs to be only reasonably level and smooth.
• Gabions are porous, requiring no costly drainage provision
Ecology: Gabions is an environmentally sensitive solution to slope stabilization. It has already been mentioned that stone fill is done with natural stones making the gabions, naturally porous allowing interaction between the land and the water table and also persuades deposition of soil in the smaller voids between the stone fill during drainage that again promote vegetation growth.
