8x10 double twisted hot dipped galvanized hexagonal woven steel gabion Mesh
Description:
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.

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.

How to install welded gabion box?
1. Ends, diaphragms, front and back panels are placed upright on the bottom section of wire mesh.
2. Secure panels by screwing spiral binders through the mesh openings in adjacent panels.
3. Stiffeners shall be placed across the corners, at 300mm from the corner. Providing a diagonal bracing, and crimped over the line and cross wires on the front and side faces. None are needed in interior cells.
4. Gabion box filled with graded stone by hand or with a shovel.
5. After filling, close the lid and secure with spiral binders at the diaphragms, ends, front and back.
6. When stacking tiers of the welded gabion box, the lid of the lower tier may serve as the base of the upper tier. Secure with spiral binders and add pre-formed stiffeners to exterior cells before filling with graded stones.
APPLICATION:
Applications of gabion mattress
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.
Loading:
50-100pieces per pallets. with accessories.
Projects:
Welded gabion box is widely used in retaining wall structures, rockfall and soil protection and so on. Welded gabions are filled on site with hard and durable stone to form mass gravity structures. And welded gabions are quicker and simpler to install than woven mesh gabions.
