Hexagonal wire mesh is made of high quality galvanized or galfan steel wires. The wires are double twisted and the edge of the mesh is reinforced by a thicker wire – selvedge wire. It can be used individually or combined with other meshes for active or passive rockfall barrier. Fastened by anchors, bolts and steel cables, hexagonal wire mesh is strong and firm enough to block the rocks or debris and minimize the damage of natural disasters.
