The standarded wire material of Tecco mesh is Zn-Al Steel Wire, with tensile strength ≥1770mpa. With using this wire material, the tensile strength 1m wide of the mesh will be not less than 150N/m. Compared with other rockfall barrier systems, the tecco mesh is made of high carbon steel wire with high strength and hardness. Tecco mesh system is the simplest structure among all the rockfall barrier systems.
