Gabion is a rectangular wire mesh box comprised of three one half turns (commonly called double twisted) to form hexagonal shaped mesh openings of Zinc galvanized and PVC coated steel wire. These mesh openings are then interconnected with adjacent wires to form hexagonal meshes. Selvedge / Edge wire which is a thicker and heavier wire is used to reinforce the edges and transverse diaphragm. It gives greater rigidity and shape to the gabion/mattresses/netting.
These Gabion boxes are filled with natural stones at the project site to form flexible, permeable, monolithic structures such as Retaining walls, sea walls, channel lining, revetments, and wires for erosion control projects.
The wire used to manufacture the Double twisted Hexagonal wire mesh is soft annealed, low carbon content mild steel wire provided with heavy coating galvanizes as per EN 10244/ASTM A 641 to prevent corrosion. In case of use in aggressive environments, it is further extruded with 0.5mm thick PVC Coating. The PVC coating is UV stabilized as per ASTM A 975.
