The stone笼mesh is mechanically woven from high corrosion-resistant, high-tensile, and ductile low-carbon steel wire, or wire coated with PVC. The box-like structure made from this mesh is known as a stone笼box. The diameter of the low-carbon steel wire used complies with ASTM and EN standards and varies according to engineering design requirements, generally ranging from 2.0 to 4.0mm. The tensile strength of the stone笼mesh wire is not less than 38kg/m², the weight of the metallic coating is typically above 245g/m², and the diameter of the edge line of the stone笼sheet is generally larger than that of the mesh wire. The length of the double twisted section must not be less than 50mm to ensure that the metallic and PVC coatings on the twisted wire are not damaged.
