The stone笼mesh is mechanically woven from high corrosion-resistant, high-strength, and ductile low-carbon steel wire, or wire coated with PVC. The box-like structures made from this mesh are known as stone笼boxes. The diameter of the low-carbon steel wire used complies with ASTM and EN standards and varies according to engineering design requirements, generally ranging between 2.0-4.0mm. The tensile strength of the stone笼wire is not less than 38kg/m², the weight of the metallic coating is typically above 245g/m², and the edge line diameter of the stone笼sheet is generally larger than the wire diameter. The length of the double twisted section must be no less than 50mm to ensure that the metallic coating and PVC coating of the twisted wire are not damaged.
