Green mesh, also known as "gabion mesh" or "gabion mesh", is assembled from various mesh sizes of green mesh sheets according to the ASTMA975-97 standard. It is a flexible, permeable, and integral support structure formed by the assembly of pre filled stone materials, commonly used in ecological protection engineering. The structure is made of high galvanized steel wire or 10% zinc aluminum alloy steel wire woven by double wire twisting, and the length of the double wire twisting part cannot be less than 45mm to ensure that the anti-corrosion performance of the twisting part is not damaged. If the environment is harsh and the pollution is severe, the surface of the steel wire can be coated with PVC to enhance its corrosion resistance.
Introduction to Green Grid
Green grid parameters
(1) Aperture: 60 * 80mm, 80 * 100mm, 80 * 120mm, 100 * 120mm, 120 * 150mm
The length of the double stranded section shall not be less than 50mm to ensure that the metal coating and PVC coating of the stranded steel wire are not damaged.
(2) Wire diameter: Stone cage mesh is divided into three wire diameters - mesh wire, edge wire, and binding wire
1. The range of mesh is between 2mm and 4mm
2. The edge wire is generally larger than the mesh wire, with a thickness of 0.5mm-1mm
3. Tie wire is generally smaller than mesh wire, with 2.2mm being the most common
(3) Steel wire tension: not less than 38kg/m2 and 380N/mm
(4) Surface treatment
1. Electrogalvanizing. The zinc content * height is 10g/m2. Poor corrosion resistance
2. Hot dip galvanizing. The high zinc content can reach 300g/m2. Strong anti-corrosion properties
3. Galvan (zinc aluminum alloy). This is divided into two materials: zinc-5% aluminum mixed rare earth alloy steel wire and zinc-10% aluminum mixed rare earth alloy steel wire. Strong anti-corrosion properties
4. PVC wrapping. The thickness of the plastic coating is generally 1.0mm, for example, 2.7mm after coating is 3.7mm. It has strong anti-corrosion properties
(5) Partition: Add a partition every meter along the length of the gabion net
(6) Size: Customizable
(7) Range compared to aperture and wire diameter
