Galfan Gabion

The zinc-aluminum alloy gabions are woven by 95% zinc and 5% or 10% aluminum coating wire, and it’s also named Galfan wire. This wire is different from the ordinary galvanized wire, with very good corrosion resistance, suitable for river training and slop protection and other water conservancy projects. Galfan steel is a new international emerging material which is very popular all over the world, especially in developed countries, because the corrosion resistance is 3 times higher than traditional pure zinc wire. The wire diameter of gabions is from 1.0mm to3.0mm and the tensile strength not less than 1380Mpa.

Due to oxidation, the surface of galvanized steel wire gradually becomes gray, but zinc aluminum alloy wire will become black.

Compared with ordinary galvanized gabions, the coating of aluminum alloy gabion has strong adhesion, abrasion resistance and corrosion resistance. Easier to install and convenient for construction. The stability of the zinc aluminum coating is similar as the pure aluminum coating, meanwhile the electrochemical protection of the zinc aluminum is the same as the pure zinc coating. So it’s an ideal anti-corrosion protective layer against the sea water. We used this wire to weave our gabions in order to extend the gabions life. According to study and statistics, this woven gabions can extend 5-10 life time.

Gabions are constructed as gabion retaining wall. Gabion retaining wall as a new type of retaining structure, with low cost, ecological advantages, wide scope of application, the flexible deformation characteristic has been more and more applied.

Gabions are ecologically used in managing the rivers such as stabilize the bank, river slop and bottom protection etc.

Gabion are used in bridge protection. Gabion bridge has been widely used in bridge, piers and slop protection.

Gabion are widely used in other aspects as mountain protection, river channel protection etc.
