How to choose the material of gabion mesh? Comprehensive analysis of galvanizing/plastic coating/Gaulvan

Gabion mesh, also known as gabion mesh, is widely used in river environments with high flow rates, severe erosion, and seepage on bank slopes. Its flexible structure can effectively adapt to uneven settlement and ensure the stability of the bank slope. In addition, the porous structure of the gabion net provides good habitat and growth conditions for animals and plants, which is conducive to the greening of soil bags and meets the requirements of ecological sustainability and engineering safety.
To meet the quality and cost requirements of different projects, there are various types of materials for gabion mesh, mainly including the following:
1、Galvanized steel wire
Low carbon steel wire is used, with a diameter range of 2.0mm to 4.0mm and a tensile strength of not less than 380MPa. The surface of the steel wire is hot-dip galvanized, and the galvanizing amount can be customized according to customer needs, up to 300g/m ².

2、Galvanized coated steel wire
Covering the surface of low-carbon steel wire with PVC or PE protective layer, it can be woven into various specifications of hexagonal stone cage mesh. This protective layer can significantly enhance the corrosion resistance of gabion mesh in highly polluted environments, extend its service life, and customize colors according to environmental needs to enhance landscape coordination.
3、Zinc 5% aluminum (or 10% aluminum) - mixed rare earth alloy steel wire (Galfan)
As a new type of material, its corrosion resistance is more than three times that of traditional galvanizing. The diameter of the steel wire ranges from 2.0mm to 3.0mm, and the tensile strength is not less than 1330MPa.

4、Zinc aluminum mixed rare earth alloy coated steel wire
Covering the zinc aluminum alloy steel wire with a PVC protective layer further enhances durability and adaptability to harsh environments, resulting in a longer service life and higher corresponding cost.
