Where gabions and gabion walls are used?
gabion is somewhat like a cage. The cage may be cylindrical or in the shape of a square or rectangular box. The cage may be constructed with a number of different materials, depending on the application. In some cases, the gabion is made with the use of metals, while gabion that are intended for temporary use may be composed of an outer shell of canvas or a similar material. Even wick has been used as the material of choice for a gabion. Gabion mesh is made from soft annealed steel wire which is additionally coated to increase its durability and design life. The coatings include: zinc galvanized, Galfan (a eutectic Zn-Aluminum (5%) MM alloy); zinc galvanized with PVC coating. Gabions can be used in many ways, including: retain unstable slopes; provide erosion control to rivers, channels and shorelines; create acoustic barriers; dressed architectural buildings and many other applications that require a permeable, flexible, durable and very cost effective structure.
