Stone cage net by high corrosion, high strength, has the ductility of low carbon steel Wire or coated PVC wire above using mechanical woven, produced by using the net box structure is stone cage area. According to ASTM and EN standard, the diameter of low carbon steel wire is different according to the engineering design requirements. Generally between 2.0 and 4.0 mm, the tensile strength of the steel wire is not less than 38kg/m2, the metal coating weight is generally higher than 245g/m2, and the diameter of the edge wire of the mesh is generally greater than the diameter of the mesh wire. The length of the double strand shall not be less than 50mm. To ensure that the metal coating and PVC coating are not damaged.
