Galvanized wire gabion mesh, gabion mesh national standard requirements:
1, galvanized gabion mesh tensile strength: 350-575 cattle / square millimeter, in line with South Africa's SANS675:1997 standard.
2. The diameter error of silk warp is within the normal range of 5%. The error of the mesh is qualified at 3%-16%.
3, ductility: greater than or equal to 10%, in line with the European 1023-3 standard, the test sample is greater than or equal to 25 cm.
4, zinc layer standard: galvanized wire ring wheel center axis 6 rounds, repeated 4 times. In accordance with the standard of sans675:1997, there is no zinc precipitate, no wrinkling, no shedding phenomenon.
5. Measurability: During the test, the meshes are intertwined at a speed of 15 per minute, and then wound at the same speed in the opposite direction, and the galvanized layer and the raw wire are not broken. Meets the SANS 675:1997 standard. The gabion mesh is connected with tie wires, and all tie wires are also made of heavy zinc plating or stainless steel wire and are operated with special tools (simple tools are also available). The typical diameter of the tie wire is 3 mm and the tensile strength is 156-178 kg/mm2.
