hexagonal gabion box

4.Providing the prefixed value of coarseness modulus of river banks

3.Protecting riverbeds from being washed away

2.Strengthening the stability of the river beds

The development and control of the river-ways concerns the technology of laying protective layer,with permanent
protective function,on sections.The ston gabion can control water flowing volume and protect water resource from running off in holding the neigh-boring water resource and protecting and controlling the zoolory.
Main Characteristics of Water conservancy
1 General evolution of watercourses

water conservancy:

Wire
All tests on wire must be performed prior to manufacturing the mesh. All wire should comply with ASTM A975-97, style 3
coating, Galfan and PVC coated steel wire. Wire used for the manufacture of gabions and the lacing wire, shall have a
maximum tensile strength of 75 000 psi (515 MPa) as per ASTM A856-03, soft temper steel.
When requesting a quote, please specify:

EXAMPLE: No. 100 Reno mattresses 4x2x0.23 m - Mesh type 6x8Wire diam. 2.2 mm- Galvanized

Gabion box :
Gabions are baskets manufactured from 8x10 double twisted hexagonal woven steel wire mesh, as per ASTM A975-97
Gabions are filled with stones at the project site to form flexible, permeable, monolithic structures such as retaining
walls, channel linings, and weirs for erosion control projects. The steel wire used in the manufacture of the gabion is heavily
Galfan (zinc-5% aluminum-mischmetal [Zn-5 Al-MM] alloy) coated soft temper steel. A PVC coating is then applied to
provide additional protection for use in polluted, contaminated or aggressive environments: in salt, fresh water, acid soil or
wherever the risk of corrosion is present. The PVC coating has a nominal thickness of 0.02 in. (0.50 mm).
The gabion is divided into cells by diaphragms positioned at approximately 3 ft (0.9 m) centers. To reinforce the structure,
all mesh panel edges are selvedged with a wire having a greater diameter.
Gabions shall be manufactured and shipped with all components mechanically connected at the production facility.

welded gabion box is made of hexagonal wire netting , which have to be anti-corrosiveness and be durable .
