Gabion Wire Mesh for Protecting Dam

galvanized gabion box 
The gabion boxes are used widely in slope protection, foundation pit supporting, mountain rock holding, river and dams scour protection.
Gabions are mainly made of four types of materials:

(1) Galvanized steel wire: Excellent low-carbon steel wire, diameter: 2.0mm-4.0mm, tensile strength: no less than 380Mpa. The surface adopts hot galvanization for protection. The depth of the protective galvanized layer (max. 300g/m₂) is decided according to customer demands. 

(2) Zinc-5% aluminum-mixed mishmash alloy steel wire: (also called galfan steel) a new kind of material appearing recently with corrosion resistance 3 times of traditional pure galvanization; diameter: 2.0mm-4.0mm; tensile strength: no less than 380Mpa.

(3) Galvanized steel wire with plastic coating: Excellent low-carbon steel with PVC or PE protective coating on the surface which will be weaved into various gabions. This protective coating will greatly increase the protection in high pollution environment. In addition, the options of different colors enable it merge into the surrounding environment.

(4) Zinc-5% aluminum-mixed mishmash alloy steel wire: alloy steel wire with PVC or PE protective coating on the surface which will be weaved into various gabions. This protective coating will greatly increase the protection in high pollution environment. In addition, the options of different colors enable it to merge into the surrounding environment.


 

Weaving of Gabions: 

I. Gabions are molded once. Except cover plates, the edge plates, end plates and bottom plates are inseparable. Length/width tolerance (±5%) height tolerance (±5%). The interior part is isolated into independent units by adopting clapboards every other 1m.

II. Gabions adopt assembly mode. The cover plates, the edge plates, end plates and bottom plates are separately assembled into cages wound by spiral steel wire. All the edge wire of the cage adopts thick wire to improve the strength of the gabions.
