Gabion net is made of high corrosion-resistant, high-strength and malleable low-carbon steel wire or PVC coated steel wire. The box structure made of the net isgabion net box. According to ASTM and EN standards, the diameter of low carbon steel wire used varies according to the engineering design requirements. Generally between 2.0-4.0mm, the tensile strength of gabion mesh wire is not less than 38kg / m2, the weight of metal coating is generally higher than 245g / m2, and the diameter of edge line of gabion mesh is generally larger than that of mesh line. The length of the double stranded part shall not be less than 50 mm to ensure that the metal coating and PVC coating of the stranded part of the steel wire are not damaged.
Wire diameter × wire diameter × base × length × width ÷ 2 = kg
Base: 1 / 2"= 2.15 1" = 1.27 3 / 4 "= 1.6 5 / 8" = 1.87 5 / 4"= 1.09
1"X1 / 2": wire diameter × wire diameter × 2x length x width ÷ 8×3 = kg
Calculation formula of gabion net weight
Gabion net is a cage made of angle net (hexagonal net) woven by metal wire. The wire diameter used is different according to the size of hexagon. In case of hexagon of metal coated wire, use metal wire with wire diameter of 2.0mm to 4.0mm; in case of hexagonal net woven by PVC coated wire, use PVC (metal) wire with outer diameter of 3.0mm to 4.0mm; in case of outer frame edge, use wire with diameter of No.1 larger than hexagonal net wire.
The box type gabion is connected by a large-scale hexagonal net. During construction, only the stones need to be put into the gabion for sealing.
Specification of gabions: 2m x 1m x 1m, 3m x 1m x 1m, 4m x 1m x 1m, 2m x 1m x 0.5m, 4m x 1m x 0.5m, which can also be produced as required by customers. The surface protection status includes hot-dip galvanizing, galvanized aluminum alloy, PVC coating, etc.
(1) Aperture: 60 * 80mm, 80 * 100mm, 80 * 120mm, 100 * 120mm, 120 * 150mm, 90 * 110mm
The length of the double stranded part shall not be less than 50 mm to ensure that the metal coating and PVC coating of the stranded part of the steel wire are not damaged.
(2) Wire diameter: there are three kinds of wire diameters for gabion Net – mesh wire, edge wire and binding wire
1. The range of mesh wire is 2mm-4mm
2. Edge wire is generally larger than mesh wire, 0.5-1.0mm thicker than mesh wire
3. The binding wire is generally smaller than the mesh wire, and the most common is 2.2mm
(3) Wire tension: not less than 38kg / m2 380n / mm
(4) Surface treatment
1. Galvanizing. The highest zinc content is 10g / m2. Poor corrosion resistance
2. Hot dip galvanizing. The highest zinc content can reach 300 g / m2. Strong corrosion resistance
3. Galfan (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 corrosion resistance
4. PVC coated. The thickness of plastic coating is generally 1.0mm, for example, 3.7mm after 2.7mm. Strong corrosion resistance
(1) Partition: add one partition per meter in the long direction of Gabion
(2) Size: can be customized according to the standard
(3) Range of hole diameter and wire diameter
