The gabion net is a cage made of angular net (hexagonal net) woven with metal wires, and the diameter of the metal wires used varies according to the size of the hexagon. If it is a metal-coated hexagonal metal wire, use a metal wire with a wire diameter of 2.0 mm to 4.0 mm; If it is a hexagonal mesh woven with PVC-coated metal wires, use PVC (metal) wires with an outer diameter of 3.0 mm to 4.5 mm, and use wires with a diameter one size thicker than that of the hexagonal mesh. The specification parameters of gabion net include wire diameter, mesh size and material of gabion net.
The wire diameter of gabion net can be 2.0 mm-4.0 mm.
The mesh of the gabion net can be 60 * 80mm80 *100mm70 * 90m90 *10mm100 *120mm120 *150mm/kloc.
The common specifications of gabion net are:
Mesh: 60mm X 80mm. Diameter range: 2.0mm-2.7mm
Mesh: 80mm X 100mm. Line diameter range: 2.0mm-3.2mm
Mesh: 90mm X 1 10mm. Line diameter range: 2.0mm-3.2mm
Mesh: 100mm X 120mm line diameter range: 2.0 mm-3.2 mm
Mesh hole:110mm x130mm line diameter range: 2.0mm-3.8mm.
The surface treatment of raw materials of gabion net includes: cold galvanized wire (also called electro-galvanizing), hot galvanized wire, high galvanized wire, zinc-aluminum alloy wire (also called Galfan) and plastic coated wire (cold galvanized wire, hot galvanized wire, high galvanized wire and zinc-aluminum alloy wire can also be coated first and then coated with plastic).
The gabion net can be made into: cage, net piece and net roll.
The gabion net is a hexagonal twisted steel wire net made of galvanized or plastic-coated low-carbon steel wire by machining, and made into an engineering component that meets the requirements. The tensile strength of steel wire woven with gabion net should be 350? 550N/mm2, the elongation of nonwoven steel wire shall not be less than 12% (the elongation of finished steel wire after weaving shall not be less than 7%). Mesh sheets and coils can be cut into a certain width and length according to the specifications required by the construction site. The specifications of gabions are slightly more complicated. The gabion cage is produced by one-step molding. Except the cover plate, the side plate, end plate and bottom plate are inseparable. Length/width tolerance (5%) and height tolerance (10%), and the interior is divided into independent units with partitions every 1 meter. Gabions are usually assembled by assembly. The cover plate, side plate, end plate and bottom plate are fabricated and assembled separately, and all parts are wrapped and bound with spiral steel wires. All the side wires of the cage are made of wires 0.5- 1.0mm thicker than the mesh wires to strengthen the strength of the gabion. The following details the specifications and parameters commonly used in gabion:
"The common specifications of gabion cages are mesh 60*80mm, 80* 100, cage size 2 * 1 * 1m, 3 *1*/m, 4 *1*/. For example, 2* 1* 1m has one partition, 3 *1* has two partitions, 4 *1* has three partitions, and 6 *1*. The allowable tolerance of the length and width of the cage is 5%, and the allowable tolerance of the height is 5%. The diameter of common mesh steel wire with 60*80mm mesh is 2.0mm, the galvanized weight is >: 2 15g/m2, the diameter of edge steel wire is 2.7mm, and the galvanized weight is >; 245g/m2. 80* 100mm mesh ordinary mesh steel wire has a diameter of 2.7mm, galvanized weight >: 245g/m2, edge steel wire diameter of 3.4mm, galvanized weight >; 265g/m2. Tie wire is generally the same as or slightly thinner than mesh. "
