Hexagonal woven mesh gabions
Hexagonal woven mesh gabions are manufactured from a mesh that has a hexagonal opening which is formed by twisting pairs of
wire together with one and a half turns (sometimes referred to as triple or double twist).
This type of mesh production is continuous. To form panels, the mesh is guillotined across the weave and the cut ends of the wire are wrapped around a heavier wire to form a selvedge end.
The unit is factory fabricated from one main panel which forms the front, base, rear and lid of the unit with additional panels connected to the base
section of the main panel to form the diaphragm and end panels.
Normally, dependant upon the manufacturer, the mesh orientation is either with the weave horizontally or with the weave vertically, on the vertical
panels. The connection of the ends and diaphragm to the base is via a spiral wire or pairs of twisted wires, twisted together around the base mesh.
This type of mesh is flexible as it can articulate about the twists.
It is normally manufactured from a 2.7mm wire diameter for gabions or 2.0mm wire diameter for mattresses. Wire coatings are either galvanised or Galfan coated.
For more aggressive environments, an additional organic polymer powder (PVC) coating should be applied to a Galfan coated base wire.
The dimension between the twists is a nominal 80mm for gabions and 60mm for mattresses.
