Gabion Basket - Flexible and Permeable Stone Container

Gabion basket also named gabion box, is weaved by corrosion resistance, high strength and good ductility galvanized wire or PVC coating wire through mechanical. Wire's material is zinc-5% aluminum alloy (galfan), low carbon steel, stainless steel or iron. Gabion mattress is similar to gabion basket. But gabion mattress's height is lower than gabion basket, structure is flat and big. Gabion basket and gabion mattress are stone containers, uniformly partitioned into internal cells, interconnected with other containers and filled with stone at site to form flexible, permeable, monolithic structures to control and guide water or flood, protect dam or seawall, or used as retaining walls, channel lining and other applications.

Specifications:

• Material: low carbon steel wire, stainless steel wire, iron wire.
• Surface treatment: galfan, galvanized, PVC coated, galvanized plus PVC coated.
• Mesh opening shape: hexagon.
• Weaving method: normal twist (double twisted or triple twisted), reverse twist (double twisted).
• Nominal thickness of PVC coating layer is 0.50 mm to 1.00 mm.
• Galvanized is hot dipped galvanized. Thickness of galvanized layer can be manufactured according to customer's requirement, most can reach 300 g/m².
• The height of gabion mattress is 0.17 - 0.5 m.
• Tensile strength of wire is above 380 Mpa. The weight of zinc layer is above 245 g/m². Selvedge wire is cruder than the mesh wire. Lacing wire is thinner than the mesh wire, such as mesh wire is 3.0 mm, selvedge wire is 3.9 mm, lacing wire is 2.4 mm.
• Length, width and height can be customized.

Features of gabion

• Compared with traditional galvanized gabion, galfan gabion has a good corrosion resistance.
• Galfan plus PVC coating gabion is stronger and more durable than galfan gabion.
• Corrosion resistant, high strength, possess ductility.
• PVC coating will increase the protection ability in high polluted environment, this gabion can fuse with surroundings through choosing different color.
• Convenient to transport and install.
• Gabion basket or mattress are formed to a flexible, permeable and monolithic structure.
• Soft structure can adapt the change, will not be damaged, has better safety and stability than rigid structure.
• Due to the spacing among stones, it has good ability of resistant to scour, silt can be left in the spacing where plant can grow.
• Low cost, long life.

Applications of gabion

• Control and guide water or flood.
• Retaining walls.
• Channel lining.
• Dam and seawall protection of scour resistance.
• Bridge and pier protection of scour resistance.
• Reservoir and river closure cages.
• Protect land from erosion.
• For Villa Landscape.

Note
Zinc-aluminum alloy is called Galfan in foreign, zinc coating is high zinc plus aluminum. Aluminum content is 5-10%, zinc content is 90-95% in Galfan. The meaning of Galfan is "an extraordinary galvanized". Corrosion resistance of the products is about 2-3 times that of ordinary galvanized. Currently, Galfan galvanized wire mainly used in gabion basket.
