As we all know, galvanized gabion mesh is made of metal, there are many corrosive substances in rivers and oceans, so the metal will be corroded when it is in contact with water for a long time, so why people choose it as a protective structure, because the surface of galvanized gabion mesh is coated with zinc layer, galvanized gabion mesh is an emerging structure that has appeared in recent years, the outer layer of this gabion mesh is processed with galvanization, just like wearing a thin layer of clothes that It does not allow fresh water elements to react with the surface of gabion mesh, so galvanized gabion mesh is not easily corroded and its service life is greatly extended.
Galvanized gabion mesh is a corrosion-resistant and wear-resistant protective mesh product, usually composed of high-strength low-carbon galvanized steel wire or 5%≤10% high-aluminum zinc alloy coated wire, which is anti-static, anti-aging and corrosion-resistant and can effectively resist seawater erosion. The length of galvanized steel wire in the double-chain part of galvanized gabion mesh should not exceed 5 cm to avoid damaging the protective layer of metal wire. All the river gabions are connected according to the design requirements of the packing project such as mesh box and stone for embankment and water conservancy construction project.
Galvanized gabion mesh is easy and convenient to construct, only need to put the stones in the cage to seal, no special technology is needed, and the cost is low, only 20 yuan per square meter, galvanized gabion mesh has good landscape and protection effect, can effectively prevent soil erosion, the service life is up to decades, usually no maintenance is needed, therefore, the Yellow River section of Yangtze River embankment project, Taihu Lake flood control embankment project, Three Gorges Sanduping embankment project Galvanized gabions are used as construction facilities.
Galvanized gabion mesh is mainly used for the protection structure of rivers, river bank slopes and road base slopes, it can prevent the river bank from being invaded and damaged by water and waves, realize the natural convection exchange function of water and soil, and increase the greening effect of the landscape. The grid specifications of galvanized gabion mesh are: 1-4m wide, 1-2m high, 3-6m long, 2m wide, 1.3m high, the diameter of steel wire is 2.0-4.0mm, the galvanized gabion mesh Service life has a great relationship with its own coating, such as the number, uniformity and firmness of the coating, which will directly affect the service life of galvanized gabion mesh. Therefore, in order to prolong the service life of galvanized gabion mesh, we can only work on factors such as the number of coatings, the uniformity of the coatings and the firmness of the coatings of galvanized gabion mesh.
Galvanized gabion mesh is a structure made of wire mesh or welded, fixed in place by rock filler, which can prevent damage caused by water erosion. Galvanized gabion mesh will not break due to wear and tear of deposits in the gabion, and the surface galvanization protection includes hot-dip galvanizing, galvanized aluminum alloy, PVC coating, etc. No matter which galvanization process, it has good corrosion resistance.
