Abstract
A wire netting, preferably used as a gravel screen or for protecting a soil surface layer is woven from corrosion-resistant wires and either fitted on the soil surface or secured in an almost upright position on a slope or something similar. The wires in the wire netting are manufactured from heavy-duty steel, which has a nominal strength in the region of 1000 to 2200 N/mm2 and steel wire may be used for this for stranded wires or spring steel wire. The wire netting is manufactured from rectangular, diagonal netting and it has a three-dimensional, mattress-like structure.
