Gabion Sack
Gabion sack is specifications cylindrical gabions, the construction of prefabricated double twisting mesh diameter 0.65 or 0.95 meters and a length of 2 to 4 meters. Gabion sack designs are in the form of cylinders with tied ends. To enhance the gabion sack, wire edges of panels has a larger diameter than the main wire mesh. Thanks to the use in the manufacture of cylindrical mesh gabions dual torsion structure resistant to deformation of individual cells, including breaks (not spreading at break of single cells and easy to repair).
Sack gabions filled with stones are used in river control and various emergency works. Sack gabions are supplied with steel reinforcing wires inserted during the manufacturing process to facilitate closing during installation.

Wire mesh used to gabion sack, made of thick steel wire galvanized or coated wire. In the case where the cylindrical gabions are used in hostile environments, wire their manufacture is the process of galvanizing (or galfan) And then additionally coated sheath of PVC (polyvinyl chloride). PVC coating wire and provides greater stability to chemical, mechanical and corrosion damage.
