Rockfall netting is used to prevent rocks and debris from falling onto roads and railways. The steel wire used in the manufacture of the mesh is heavily zinc coated soft temper steel.

In order to increase the wire durability, the steel wire used in the manufacture of the gabion can also be heavily galvanized with Galfan, a Zn-5%Al-MM(mischmetal) alloy. In order to reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter. Due to the characteristics of double twist, the steel wire mesh can withstand the force of falling rocks without unraveling in event of wire breakage.
