| Sack Gabions consist of a single mesh panel made of hexagonal woven wire Mesh Type 80, commonly referred to as double twist wire mesh. Sack Gabions are filled with rock at the project site to form flexible, permeable, monolithic structures used for emergency and river training works where local conditions require fast installation or where the water does not allow for easy access to the site and where underwater installation is necessary. The steel wire used in the anufacture of the sack gabion is heavily zinc coated. When required, a 0,5mm nominal thick PVC coating is then extruded over the galvanised wire to provide added protection for use in aggressive environments. The end of the mesh is edged with steel rods inserted during the manufacturing process to allow for faster closing during installation.. |
