Gabions are baskets manufactured from Galvanized double twisted hexagonal woven steel wire mesh. Gabions can also be made using Galfan wire. Galfan is an alloy made of zinc – 5% aluminum – mischmetal.
A PVC coating can 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.
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.
