This specification covers gabions and revet mattresses produced from double-twisted metallic-coated wire mesh, and metallic-coated wire for lacing wire, stiffeners, and fasteners used for manufacturing, assembling, and installation of the product. Double-twisted wire gabions and revet mattresses are classified according to coating, as follows: Style 1, Style 2, Style 3, Style 4. The wire used in the manufacture of double-twisted mesh for use in gabions and revet mattresses shall conform to the specific styles. Lacing wire and stiffeners shall be made of wire having the same coating material as the double-twisted wire mesh. The mechanical properties such as tensile strength shall be meet for the different styles of wires. Coatings shall conform to the required specific gravity, tensile strength, modulus of elasticity, hardness, and brittleness temperature, resistance to abrasion, salt spray exposure and ultraviolet exposure.
