Galfan Gabion Mesh
Galfan Gabion Mesh is a kind of hexagonal wire mesh container, which is woven by Zn-Al rare earth alloy coated steel wire. The 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.
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.
Welded Gabion Box, HESCO Bastion,
Welded gabion mattress is manufactured from cold drawn steel, electronically welded at each section to form welded mesh panels and covered with PVC coating for additional anti-corrosive property.
The PVC coated heavy hexagonal mesh is manufactured from low carbon steel wire and coated with a PVC coating to strengthen the anti-corrosive property.
Gabion mattress is also called reno mattress, it is mainly composed of double twisted hexagonal wire mesh, thus the mesh shape is often hexagonal shape.
