Gabions are used in many situations including the stabilization of earth movement and erosion, river control, reservoirs, canal refurbishment, landscaping and retaining walls. Double-twisted wire gabions and revet mattress are classified according to coating, as follows:
Style 1, consists of double-twisted wire mesh made from wire which is zinc coated before being double-twisted into mesh.
Style 2, consists of double-twisted wire mesh made from wire which is coated with Zn-5Al-MM (Galfan) before being double-twisted into mesh.
Style 3, consists of double-twisted mesh, and lacing wire as style 1 and overcoated with PVC.
