Gabion box is made of double twisted hexagonal woven steel wire mesh, as per ASTM A975-97
gabion boxes 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 manufacturing of the gabion box 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 orwherever the risk of corrosion is present. The PVC coating has a nominal thickness of 0.02 in. (0.50 mm).

Gabion box 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.
