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.
GS-1: Gabion sack is a cylindrical bag filled with stones used in river training work.
GS-2: Gabion sack has stone spacing to convenient plant to grow and resistant to scour.
GS-3: Galvanized gabion sacks full of stones can be used as road after raining.
GS-4: PVC coated hexagonal wire mesh can be used for gabion sack with good anti-corrosion.
GB-5: Gabion sack holds rocks inside.
GB-6: Gabion sacks take rocks on water for transportation.
GB-7: Hanging the steel wire into the excavator.
GB-8: Placing gabion sacks which contain rocks on a river bank as a barrier.
