Sack gabions, which are made of 8×10 double twisted steel woven wire mesh, are cylindrical baskets. They are filled with stones at the construction sites, and have good flexibility and permeability. The material of the sack gabion is steel wire that is heavily galvanized low carbon steel. In addition, all the mesh panel edges are selvedged with wire of a greater diameter to reinforce the structure. In order to meet different customers' requirements, the galvanized sack gabions’ dimensions and sizes can be customized.
Characteristics:
1. Economical and practical-Needless of special skills. You just need to put filling materials into the sack gabions.
2. Convenient transportation-It can be folded for transportation and then installed on site.
3. It can effectively resist wretched weather as well as natural damage.
4. It can suffer large deformation without collapsing.
5. Good permeability prevents the damage caused by hydrostatic force.
Installation and Filling
Rocks for sack gabions can be produced by any proper quarrying method. They should be of high hardness, whether they are angular or round. What’s more, high quality rocks, which shall range between 100mm and 200mm, should be able to withstand current scour as well as weathering. Generally speaking, the range in sizes may allow for a variation of 5% oversize or 5% undersize rock. On any account, the oversize rock shall not be larger than 250 mm, and the undersize rock shall not be smaller than 80 mm. When the sack gabion has been filled properly, the ends of the top spiral wire are pulled tight, twisted and looped onto itself. In order to minimize voids and at the same time achieve a maximum density of the rock in the sack gabions, manual handling is quite necessary.

Major Applications of Sack Gabions:
Sack gabions can be extensively used in highway, railway, hillside afforestation, building and breeding, flood fighting net cage, revetment fence, controlling and guiding the direction of river, spillway and diversion channel, rock fall protection, prevention of water loss and soil erosion, embankment protection, protection of the bridge, retaining wall and so on.

Packing Terms:
Basically, all sack gabions are supplied in the form of bundles, which are compressed and strapped together at the factory for easy shipping and handling. Lacing wire is supplied in coils. Ring fasteners are shipped in boxes which must be stored in dry conditions.
