Gabion mesh specification
Gabion mesh is a type of wire mesh made from galvanized steel wire. It is commonly used in civil engineering and construction projects for erosion control, slope stabilization, and retaining wall construction. The specifications of gabion mesh can vary depending on the specific project requirements. Here is a general guideline for gabion mesh specification:
1. Wire diameter: The wire diameter of gabion mesh is typically between 2.0mm to 4.0mm. The specific wire diameter can be determined based on the engineering design and the expected load-bearing capacity of the gabion structure.
2. Mesh size: The mesh size of gabion mesh refers to the opening size between the wires. It is usually measured in millimeters. Common mesh sizes for gabion mesh range from 60mm x 80mm to 100mm x 120mm. The choice of mesh size depends on the size of the stones or rocks that will be used to fill the gabion baskets.
3. Selvedge wire: The selvedge wire is the wire that runs along the edges of the gabion mesh panels. It is usually thicker than the regular wire and provides additional strength and stability to the gabion structure. The selvedge wire diameter is typically 0.5mm to 1.0mm thicker than the regular wire diameter.
4. Tensile strength: The tensile strength of gabion mesh is an important factor in determining its load-bearing capacity. The tensile strength is usually specified in terms of the breaking load, which is the maximum load that the gabion mesh can withstand before breaking. The breaking load can vary depending on the wire diameter and the type of steel used.
5. Zinc coating: Galvanized gabion mesh is coated with a layer of zinc to protect it from corrosion. The zinc coating thickness is typically specified in terms of the weight of zinc per unit area, usually expressed in grams per square meter (g/m²). Common zinc coating thickness for gabion mesh ranges from 220g/m² to 300g/m².
6. Panel size: Gabion mesh panels are usually supplied in standard sizes, which can vary depending on the manufacturer. Common panel sizes for gabion mesh range from 2m x 1m to 6m x 2m. The panel size can be customized to fit the specific project requirements.
7. Lacing wire: Lacing wire is used to join the gabion mesh panels together. It is typically made from the same galvanized steel wire as the gabion mesh. The lacing wire diameter is usually smaller than the regular wire diameter, typically around 2.0mm.
In conclusion, the specification of gabion mesh includes wire diameter, mesh size, selvedge wire, tensile strength, zinc coating, panel size, and lacing wire. These specifications can be customized based on the specific project requirements to ensure the desired performance and durability of the gabion structure.
