Galvanized wire rope net is the most common used rockfall barrier type. It is made of hot dipped galvanized steel wire rope. The wire ropes are intersected and fixed by the clips. The steel wire rope has higher tensile strength than the steel wires. The galvanized wire rope net can be used individually or it can be used with chain link fence or hexagonal wire meshes. When it is used individually, it is commonly used in the mountains which the stones is large and the impact is huge. When it is used combined with chain link fence or hexagonal wire mesh, the mountain or the slope is loose and have several small stones. The chain link fence or the hexagonal wire mesh can block the small stones.
