The double twisted gabion wire mesh made by twisting continuous pairs of wires through three one-half turns (commonly called double twisted )to form hexagonal-shaped opening which are then interconnected to adjacent wire to hexagonal openings.
The wire used to manufacture double twisted gabion wire mesh is soft annealed, mild steel wire provided with heavy zinc coating as per EN 10244/ASTM A641 to prevent corrosion. In case of use in aggressive environments, it is further extruded with 0.5mm thick PVC Coating. The PVC coating is UV stabilized as per ASTM A 975.
Selvedge/Edge wire which is a thicker and heavier wire is used to reinforce the edges and transverse diaphragm. It gives greater rigidity and shape to the Gabion Basket.
