One distinct advantage of knitted mesh depends on its special interlocking loop which acts as a small spring. When subjective to tensile or compressive stresses, knitted wire mesh will not distort beyond its yield point. And the knitted mesh will resume its original shape when stress is moved. In addition, copper mesh will not be troubled by rust and corrosion problems. For this reason, copper wire mesh is often used in outdoor applications such as gardens and roofs.
