Stackable Gabion Wall Cages , Retaining Wall Using Gabion Baskets
Stackable 1 × 1 × 2M Galvanized Gabion Wire Mesh Cage Wall For River Protection
Gabion baskets manufactured from 8 × 10 double twisted hexagonal woven steel wire mesh or welded wire mesh, as per ASTM A975-97 Gabions are filled with stones at the project site to form flexible, permeable, monolithic structures such as gabion retaining walls, channel linings, and weirs for erosion control projects. The steel wire used in the manufacture of the gabion is heavily Galfan (zinc-5% aluminum-mischmetal [Zn-5 Al-MM] alloy) coated soft temper steel. A PVC coating is then applied to provide additional protection for use in polluted, contaminated or aggressive environments: in salt, fresh water, acid soil or wherever the risk of corrosion is present. The PVC coating has a nominal thickness of 0.02 in. (0.50 mm). The gabion is divided into cells by diaphragms positioned at approximately 3ft (0.9 m) centers. To reinforce the structure, all mesh panel edges are selvedge with a wire having a greater diameter. Gabions shall be manufactured and shipped with all components mechanically connected at the production facility.
The strength of gabions comes from a double twisted hexagonal steel wire mesh which is reinforced by selvedges of heavier wire running along the edges and by transverse diaphragms. The double twisted wire will not unravel, even when the gabion is cut.
