Based on the different raw materials of the steel wire, gabion mesh is classified according to its effective corrosion resistance: galvanized gabion mesh, Galfan-coated (zinc-10% or 5% aluminum-rare earth alloy) gabion mesh, and PVC-coated gabion mesh. Galvanized gabion mesh was once widely used hexagonal wire mesh, while Galfan gabion mesh is a newer material internationally in recent years, offering superior corrosion resistance—more than three times that of traditional galvanized steel wire gabion mesh.
Therefore, Galfan galvanized gabion mesh has gained widespread popularity and is continuously being promoted; it is now a widely used material in Europe and America. The PVC coating of PVC-coated gabion mesh protects the galvanized steel wire from corrosion in highly polluted environments, resulting in a relatively longer service life. Furthermore, the PVC layer offers a variety of colors to choose from, allowing it to blend harmoniously with the surrounding environment.
According to their uses, gabions and gabion mesh can be classified as follows: Widely used in highway and railway fencing, slope protection, slope beautification, mountain slopes, shotcreting, well and tunnel protection, construction, livestock fencing, zoo fencing, grassland fencing, and diamond-mesh fencing, these hexagonal meshes primarily serve a fencing and protective function, and therefore can be categorized as fencing and protective netting.
Also used in controlling and guiding river courses, flood discharge dams and diversion channels, rockfall protection, bridge maintenance, soil stabilization structures, retaining walls, preventing soil erosion, coastal protection projects, and port projects. These are primarily used in water conservancy and river management projects, and therefore can be classified as water conservancy and river management protective netting. In this application area, gabions are typically presented in the form of gabion boxes, gabion baskets, gabion cages, gabion mats, Reno mattresses, and other similar shapes.
Its high permeability and solid internal stone filling can effectively weaken the scouring of strong river water. Different steel wire materials can also effectively resist corrosion in long-term humid environments. In addition, a layer of soil can be spread on top of the installed gabion mesh box to grow green vegetation, thus possessing green ecological properties.
