Features:
1. Galfan offers a more homogenous, ductile and smoother coating than does galvanized zinc. The result is that the galfan is less affected by abrasion.
2. Galfan coating offers up to 3 times better corrosion protection than standard zinc coating in salt spray test, and up to 2 times better corrosion protection than standard zinc coating in the SO2 Atmosphere test. Galfan offers better sacrificial protection of the steel wire than standard galvanized zinc.
3. Gabion galfan use the same wire diameters as the galvanized gabions. This is an advantage in corrosive environments that have a reduced steel wire diameter as compared to other similar products. The result is a better corrosion protection coating than the galvanized zinc or the PVC coated.
4. It is recommended that galfan coating be utilized when corrosion is the predominant factor for determining the expected life span of the mesh structure.
Applications:
* Water and soil protection
* Bridge protection
* Strengthening structure of soil
* Protection engineering of seaside area
* Control and guide of water or flood
* Flood bank or guiding bank
* Preventing of rock breaking
