Gabion mesh

Gabion mesh is an ecological grid structure. Gabion mesh is mechanically woven from high corrosion-resistant, high-strength, ductile low-carbon steel wire or PVC-coated steel wire. The box-shaped structure made from this mesh is called a gabion. According to ASTM and EN standards, the diameter of the low-carbon steel wire used varies based on engineering design requirements, generally ranging between 2.0-4.0mm. The tensile strength of the steel wire is not less than 38kg/m², and the metal coating weight is generally above 245g/m². The edge wire diameter of the gabion mesh is typically larger than the mesh wire diameter. The length of the double-wire twisted part must not be less than 50mm to ensure that the metal coating and PVC coating of the twisted wire are not damaged.    

Product Applications:

This structure can be used for slope support, foundation pit support, rock face mesh spraying for mountain slopes, slope vegetation (greening), and isolation guardrails for railways and highways. It can also be made into box cages and mesh pads for scour protection of rivers, embankments, and seawalls, as well as for river closure and reservoir applications.    

1. Control and guidance of rivers and floods  

The severe disaster of rivers is the erosion of riverbanks by water flow, leading to destruction, flooding, significant loss of life and property, and extensive soil erosion. Therefore, in addressing these issues, the application of this ecological grid structure has become one of the best solutions, providing permanent protection for riverbeds and banks.    

2. Channel and canal riverbeds 

The construction of channels involves the stability of slopes and riverbeds. Thus, the use of ecological grid structures has been a primary method for many natural river modifications and artificial channel excavations over the past century. It effectively provides permanent protection for riverbanks or riverbeds, controls water flow, prevents water loss, and offers excellent benefits in environmental protection and water quality maintenance.    

3. Bank and slope protection  

The application of ecological grid structures in riverbank protection and slope toe protection is a highly successful example. It fully leverages the advantages of ecological mesh, achieving ideal results that other methods cannot.  

Advantages:

1. The flexible structure can adapt to slope changes without damage, offering better safety and stability compared to rigid structures;  

2. Strong anti-scour capability, able to withstand high water flow velocities up to 6m/s;  

3. The structure is inherently permeable, highly accommodating to natural groundwater action and filtration. Suspended solids and silt in water can settle in the gaps between the stones, promoting the growth of natural vegetation and gradually restoring the original ecological environment.
