Gabion's life and its long-term corrosion resistance of materials are closely related, so do the embalming significance is very significant.
The main factors control the corrosion performance of the following four points:
1. aluminum-zinc alloy gabion corrosion resistance is much greater than the galvanized steel wire, because the corrosion rate of aluminum-zinc alloy gabions is relatively low, so gabion material best choice alloys.
2. The more zinc coating, corrosion resistance, the smaller the corrosion rate. So gabion degrees layers of zinc can prevent good gabion corrosion.
3. coating uniformity. . Ring-shaped distribution of the coating on the outer surface of the steel, coated steel wire production process less thick side of the thin side, and its useful life is weak at the control point. Although the coating weight that can reach 250g / ㎡, the real effective coating amount available is only about 100g / ㎡. While 10% aluminum-zinc alloy coated steel coating is relatively uniform.
4. coating fastness. Once the coating cracked, gabion very susceptible to corrosion. Since gabion weaving is twisted, so the coating fastness requirements are relatively high.
