Galfan Coated Stone To Fill Gabion Baskets , Wire Cages For Rock Retaining Walls
Products Description:
Galfan offers a more homogenous, ductile and smoother coating than does galvanized zinc. The result is that the galfan is less affected by abrasion. 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.
Galfan coated Gabion box can be supplied in various length, width and height. In order to strengthen the box, all the edge of the structure shall be selvedged with bigger diameter wire.

Gabion box application:
Gabion advantage
1).Flexible structure to adapt to changes in the slope without being destroyed, better than the rigid structure with the security and stability;
2).Anti-erosion ability, able to withstand the maximum flow rate of up to 6m/s.
3).This structure has essentially permeability, groundwater and the filtering effect of the natural role of a strong inclusive, suspended matter and silt in the water to move in to fill the crevice in precipitation, which is conducive to the growth of natural plants, and gradually restore the original ecological environment.
