Sack Gabion Bag

Sack gabions are cylindrical baskets made of 8x10 double twisted steel woven wire mesh, with mechanical characteristics higher than the ones suggested from EN 10223-3. 
Sack gabions are filled with stones at the project site to form flexible and permeable structures used in river trainings and various emergency works. Sack gabions are supplied with steel reinforcing wires inserted during the manufacturing process to facilitate closing during installation. The steel wire used in the manufacture of the sack gabion is heavily galvanized soft temper steel. In order to reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter.
Wire. In order to meet different customers' requirements, the galvanized sack gabions’ dimensions and sizes can be customized.
All tests on wire of sack gabions must be performed prior to manufacturing the mesh. 
(1)Tensile strength: the wire used for the manufacture of gabions shall have a tensile strength between 380-550N/mm2 exceeding, in order to increase the tensile resistance of the finished products, what is suggested from EN10223-3. Wire tolerances are in accordance with EN 10218.
(2)Elongation: Elongation shall not be less than 10%, according to EN 10223-3.Test must be carried out on a sample at least 25 cm long. 
(3)Zinc coating: minimum quantities of zinc shown at Table 4 meet the requirements of EN 10244-2
(4) Adhesion of zinc: the adhesion of the zinc coating  to the wire shall be such that, when the wire is wrapped six turns around a mandrel having four times the diameter of the wire, it does not flake or crack when rubbing it with the bare fingers.

Characteristics of Sack Gabion:

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% under size rock. On any account, the oversize rock shall not be larger than 250 mm, and the under size 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.

Gabion cage is a column form bag woven by double hexagonal nettings, which is to the standard of ASTM A975-97, and there is a piece of thick wire for belding to close the opening.

 When it is used, its filled with selected stones to make a stable building material with good water permeability to prevent or control flood.

 We control and check the producing procedure sincerely and all of the wires are sincerely to ASTM A975-97, i.e tensive strength is above 75000psi 515Mpa ASTM A641/A641M-03
