How to detect the quality of Gabion products
How to detect the Gabion products that users buy is qualified. This is a concern for all users. First, we should check the tolerance range of Gabion's wire diameter, the tolerance range of the mesh, and the amount of zinc and aluminum in the material. Tensile strength elongation and so on. If the bread is plastic, it depends on whether it is PE or PVC.
1. Gabion tensile strength: 350-575 N/mm 2, in line with South Africa's SANS 675:1997 standard. 2. The diameter error of the filament is within the normal range of 5%. The error of the mesh is qualified from 3% to 16%.
2, Gabion ductility: greater than or equal to 10%, in line with the European 10223-3 standard, the test sample is greater than or equal to 25 cm.
3, Gabion zinc layer standard: galvanized wire ring wheel central axis 6 rounds, repeated 4 times. In line with the sans675:1997 standard, no zinc deposits are not wrinkled and no shedding.
4. Gabion measurability: During the test, the mesh is wound at 15 speeds per minute and then wound at the same speed in the opposite direction. The galvanized layer and the original yarn will not break. Meets the SANS675:1997 standard. The Gebin network is connected by a tie wire. All the wire is also made of heavy galvanizing or stainless steel wire and can be operated with special tools (simple tools). Generally, the wire has a diameter of 3 mm and a tensile strength of 156-178 kg/mm 2 .
