PVC Mesh

Metal Gabion-Netting is metallic wire mesh rock fall netting used to prevent rock and debris from falling on to road and railways, since the double-twist, hexagonal-woven mesh does not unravel when some wires break. This is achieved by joining together rolls of mesh fabric with lacing wire and using it as a blanket to cover slopes obstructing rock falls. Fractured stones are trapped and confined against the slope should isolated wires fatigue from prolonged stress. This solution can also help in establishing and protect infrastructure.

Additionally, this double-twisted hexagonal type of netting has the high mechanical resistance required to prevent the danger of sudden rock shock loads and dissipate rock fall energy created from loose fractured rock.

Advantages:

1. Metal Gabion made of hexagonal double twisted wire mesh provide adequate strength to the structure to withstand forces generated by retained earth and flowing water.

2. The flexibility of the double twisted hexagonal mesh helps in withstanding differential settlement without fracturing the structure particularly when a structure is installed on unstable and uneven ground or in an area where scours from waves or current can undermine etc. 

3.  The permeable nature of the Metal Gabion eliminates buildup of hydrostatic pressure behind the retaining structure and uplifts caused by turbulent flows. Hence the thickness of the required structure is significantly reduced. 

4.  Metal Gabion structures are heavy monolithic gravity units able to withstand earth's thrust. Its efficiency increases instead of decreasing with age since further consolidation takes place as silt and soil collect on the voids and vegetation establishes itself.
