Gabion baskets manufactured from 8x10 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).
