Gabion meshes are divided into cells with diaphragms (usually spaced at 1 meter or 3 intervals), whose function is to reinforce the structure. The mesh (except for the diaphragms) is reinforced on all edges with wires of a larger diameter to strengthen the gabions and facilitate the assembly and installation.INTERNATION STANDARD TO FOLLOW:ASTM 975 standard:Style 1 galvanzied wire as per ASTM A 641, class 3 soft temperStyle 2 style 1 and overcoated with PVCStyle 3 Zn-5Al-MM coated wire as per ASTM A 856EN 10223-3 standard:Galvanzied wire meets EN 10244-2 and old BS 443Tensile strength between 420N/mm2 and 500N/mm2 according to EN 10218-2TOLERANCES: On the hexagonal, double-twisted wire mesh opening shall not exceed 10% on the nominal dimension D values (see figure)Packing: For easy handling and shipping, the gabions are supplied folded flat. A color stripe applied on the side of each folded gabion identifies the size. Usually, gabions will be loaded into 40ft containers to save cost.Gabion Gabions are rectangular wire mesh baskets filled with rock at the project site to form flexible, permeable, monolithic structures such as retaining walls for commercial, industrial and road projects. They are also used for erosion control, bank stabilization, channel linings, and weirsOur gabion strength comes from a double twisted hexagonal mesh of steel wire which is reinforced by selvedges of heavier wire running along the edges and by transverse diaphragms. The double twisted wire will not unravel, even when cut.Our gabions assembly is easy, requiring no specialized labor and nearby rock can be used for fill. They are available with different levels of protective coating for durability. With 30% voids gabion structures offer free drainage providing higher bank stability when used for river bank protection.Advantages of woven gabionsMonolithic and Flexible structuresTolerates differential settlementUniform wire coating for extra durabilityPermeable structuresPre-assembled units for fast installation and higher quality productNo specialized labor required for installationSoil Bioengineering.Gabions (from Italian gabbione meaning "big cage"; from Italian gabbia and Latin cavea meaning "cage") are cages, cylinders, or boxes filled with soil or sand that are used in civil engineering, road building, and military application. For erosion control caged riprap is used. For dams or foundation construction, cylindrical metal structures are used. In a military context, earth or sand-filled gabions are used to protect artillery crews.

he wire diameter is different according to the size of the hexagon. The materials to make gabion mesh can be divided into four types. The first type is the hot-dipped galvanized wire, which can be classified into common hot-dipped galvanizing with the amount of zinc coating 50G/M2 and high galvanizing with the export standard for 250-270G/M2. The second type is the electro galvanized wire. The following type is the PVC coated wire. It can be PVC coated after either electro galvanizing or hot-dipped galvanizing. A variety of colors are available like grey, grass green and dark green, etc. The last type is the Galfan steel wire, which can be divided into Zn-5%Al wire and Zn-10%Al wire. Hot-dipped 10% Zn-Al gabion mesh or hot-dipped 5% Zn-Al gabion mesh (also called Zn-10%Al gabion mesh or Zn-5%Al gabion mesh) is woven with various specifications of 10% (or 5%) Zn-Al alloy low carbon steel wire. Under the same conditions, the hot-dipped 10% Zn-Al alloy steel wire will have a relatively longer service life compared with the 5% Zn-Al alloy steel wire. In order to prolong the service life of the steel wire, a layer of PVC or PE coating will be added on the surface of the steel wire. Advantages of the Galfan Gabion Mesh:Galfan gabion mesh has a high corrosion resistance performance, which is about 2-3 times higher than that of the common galvanized gabion mesh under any conditions whether in the open air or in damp environment.It has a high ductility and deformability. The Galfan steel wire can withstand the test of winding and twisting under powerful deformation processes, and the zinc coating will not peel off.Application:Galfan gabion mesh can be used for slope protection, hillside afforestation, railway and highway fence, etc. It can also be made into gabion box or gabion mattress for the purpose of protecting rivers, dams and seawalls against water erosion.Zinc-aluminium alloy is in recent years emerging as a kind of new coating material on the international market to replace the traditional pure zinc coating. Experiments provide evidence that its corrosion resistance is three times higher than that of the traditional pure zinc coating. Therefore, it is now receiving widespread attention. Nowadays, some developed countries like America and some European countries are trying to replace the traditional zinc coating gabion baskets with 5% Zn-Al alloy gabions. The material of the 5% Zn-Al alloy gabion is 5% Zn-Al alloy steel wire. It is made into hexagonal mesh through weaving and then twisting three times by a special machine. According to the design requirements, the mesh panels may be clipped and then assembled into the form of different wire mesh containers. When the gabions are filled with rocks or stones, they can be used for the protection of embankment, subgrade, and river bank, etc. Another type of Zn-Al alloy gabion is the 10% Zn-Al alloy gabion, which is made from the 10% Zn-Al alloy steel wire. Just like the 5% Zn-Al alloy gabion, it is also a hexagonal mesh woven and twisted by a special machine. The gabion box is finally formed through folding the whole mesh. Its application is nearly the same as that of the 5% Zn-Al alloy gabion, which is mainly used for the protection of subgrade, and embankment, etc. The service life of the Zn-Al alloy gabion is typically about 70 to 80 years, which is 3 times longer than the common galvanized steel wire. It has reached the national standard GB/T 20492-2006. 5% (10%) Zn-Al alloy gabions are mainly applied in damp environment, such as river, sea and other water conservancy projects. Its acid resistance, alkali resistance and corrosion resistance properties are far superior to the common low carbon steel wire products
