| | | Gabions are baskets manufactured from 8x10 double twisted hexagonal woven steel wire mesh, as per ASTM A975-97 Gabions are filled with stones at the project site to form flexible, permeable, monolithic structures such as retainingwalls, channel linings, and weirs for erosion control projects. The steel wire used in the manufacture of the gabion is heavilyGalfan (zinc-5% aluminum-mischmetal [Zn-5 Al-MM] alloy) coated soft temper steel. A PVC coating is then applied toprovide additional protection for use in polluted, contaminated or aggressive environments: in salt, fresh water, acid soil orwherever 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 3 ft (0.9 m) centers. To reinforce the structure,all mesh panel edges are selvedged with a wire having a greater diameter. |
