Gabions are baskets made of double twisted steel woven wire mesh, with mechanical characteristics higher than the ones suggested from EN 10223-3 (European Norms). Gabions are filled with stones at the project site to form flexible, permeable, monolithic structures such as retaining walls, channel linings, and weirs for erosion control projects. The steel wire used in the manufacture of the gabion is heavily zinc coated (Galmac, or PVC coated) soft temper steel. The gabion is divided into cells by means of diaphragms positioned at approximately 1m centers. In order to reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter.
