The wire mesh panels 10A and 10 of each of the above embodiments
In B and 10C, when they are folded at the position of the fold line 17, since the mesh portions are double overlapped, the thickness of the whole folded wire mesh panel is substantially twice the thickness of the diamond-shaped wire mesh 11. . Therefore, in order to make the thickness of the folded wire netting panel as thin as possible to facilitate packing and transportation, it is desirable to form the netting parts that overlap with each other by using diamond-shaped wire netting having different column line shapes.

That is, generally, the rhombus wire mesh is formed by connecting the column wires 16 wound in a flat spiral shape to each other, and when the spiral direction in the column wire is right-handed, a standard mesh is formed. A rhomboid wire mesh is obtained, and when the spiral winding direction is left-handed, a reverse mesh diamond wire mesh is obtained. Then, when these standard mesh diamond wire meshes and reverse mesh diamond wire meshes are overlapped, the row lines of which the spiral winding directions are opposite to each other fall between the spirals and overlap in the thickness direction of the metal mesh. Therefore, the total thickness of the polymerized wire nets is smaller than that in the case where standard diamond mesh nets or reverse mesh diamond nets are polymerized.

Therefore, in the case of the wire mesh panel 10A of the first embodiment shown in FIG. 1, the left and right mesh portions 10a and 10b are formed by standard mesh or reverse mesh diamond mesh, and the central mesh portion 10c is formed by reverse mesh.
