Galvanized Gabion Wire Mesh Corrosion Resistance Cylindrical Gabion Basket Stone Bag

                                     Galvanized/ PVC Coated Gabion Sack - Corrosion Resistance Cylindrical Stone Bag

Gabion sack is cylindrical bag woven by double twist hexagonal wire mesh. The wire of sack gabion is galfan, heavily galvanized, PVC coated or heavily galvanized plus PVC coated. Edge wire is thicker than the wire of mesh. It supplies with steel reinforcing wire inserted during the manufacturing process to facilitate closing during installation.

Gabion sack is filled with rocks at the project site, then placed tightly one by one. The structure is similar to gabion basket: flexible, permeable and monolithic structure. It can be used in emergency situation and river training, also provide defense from the erosion effect of water. Or it could be used as rocks transportation bag. On account of its flexible woven method and unfixed shape, it is hard to be cut off by rocks when place gabion sacks under water or on the bank of river. Therefore it is able to be filled and block sediment up under water.

When installing, it should be take care that do not damage the galvanized layer and PVC coating.
