Zinc-aluminium alloy is in recent years emerging as a kind of new coating material on the international market to replace the traditional pure zinc coating. Experiments provide evidence that its corrosion resistance is three times higher than that of the traditional pure zinc coating. Therefore, it is now receiving widespread attention. Nowadays, some developed countries like America and some European countries are trying to replace the traditional zinc coating gabion baskets with 5% Zn-Al alloy gabions.
The material of the 5% Zn-Al alloy gabion is 5% Zn-Al alloy steel wire. It is made into hexagonal mesh through weaving and then twisting three times by a special machine. According to the design requirements, the mesh panels may be clipped and then assembled into the form of different wire mesh containers. When the gabions are filled with rocks or stones, they can be used for the protection of embankment, subgrade, and river bank, etc.
Another type of Zn-Al alloy gabion is the 10% Zn-Al alloy gabion, which is made from the 10% Zn-Al alloy steel wire. Just like the 5% Zn-Al alloy gabion, it is also a hexagonal mesh woven and twisted by a special machine. The gabion box is finally formed through folding the whole mesh. Its application is nearly the same as that of the 5% Zn-Al alloy gabion, which is mainly used for the protection of subgrade, and embankment, etc.
The service life of the Zn-Al alloy gabion is typically about 70 to 80 years, which is 3 times longer than the common galvanized steel wire. It has reached the national standard GB/T 20492-2006. 5% (10%) Zn-Al alloy gabions are mainly applied in damp environment, such as river, sea and other water conservancy projects. Its acid resistance, alkali resistance and corrosion resistance properties are far superior to the common low carbon steel wire products.
