Galfan Coating 6x2M Gabion
Galfan Mattress Introduction:
Galfan mattress are manufactured from 95% Zn and 5% Al coated double twist hexagonal wire mesh, and are normally supplied 6 x 2 m dimensions with a thickness less than 500mm. Mattress are filled with stones on site to create a flexible, permeable and monolithic structure for use in river and canal bank protection works as well as erosion control and scour protection of slopes.
The galfan coating provides improved corrosion resistance in comparison to a conventional galvanized coating, combining, in effect, the passive corrosion inhibition of aluminum oxidation with the active and passive effects of zinc. Galfan (95% zinc, 5% aluminium) has proven to be 2 to 3 times more corrosive resistant than the same thickness of hot dipped galvanized. Depending on the environment, it may take 50 years to 150 years for 5% rust to show on the surface of galfan when above ground.

Galfan Mattress various characteristics:
(1) Economic. Just fill the stone into the gabions and seal it.
(2) Simple installation. No special technology needed.
(3) Weather proof under natural destroy, corrosion resistant.
(4) No collapse even under big scope of deforming.
(5) Sludge in the stones is good for plant growing. Mixed to form a
integrity with the natural environment.
(6) Good permeation can prevent the damage by hydrostatic.
(7) Less transport freight. It can be folded together for transport
and further installation.
Mattress shall be manufactured with a 6 x 8 mesh type having a nominal mesh opening of 64 x 83 mm (2.5 by 3.25 in.). Tolerances on the mesh opening shall not exceed ± 10% on the nominal dimension.
