For example, the convex surface arranged as a tiled tone, a brick-tone tone, a block tone tone, or a masonry tone tone pattern so that the decorative surface 12 is surrounded by the joint tone pattern 15 by embossing or stamping such as pressing. On the surface of the partial region unit 16, at least four lines, such as a substantially left oblique stripe tone 16 b, a substantially right oblique stripe tone 16 c, a substantially parallel stripe tone 16 d, and a substantially vertical stripe tone 16 e, with respect to the lower ridge line 16 a of the convex region 16. By randomly arranging the convex region units 16 having a parallel uneven pattern based on substantially parallel stripes in the direction, the reflected light to the viewer depends on the degree of light reflection of the convex region units 16. The reflective surface that looks bright and bright, the reflective surface that looks dark with little reflected light, and the reflective surface that is located between them appear as decorative patterns in which the color tone and color density of the convex region units 16 are different at random. In addition, the decorative pattern that looks different in color tone has the effect of changing the color tone and color shading in various ways due to the change in the position of sunlight or other light sources and the change in the position of the viewer. This has the effect of improving the design, decoration, and good appearance of the metal wall material and significantly increasing its commercial value.

In the construction of the wall material 10, as shown in FIG. 3, the male edges 17 of the wall materials A and 10a are fitted to the female edges 18 of the other wall materials B and 10b adjacent to each other above the wall materials A and 10a. In addition, it can be constructed in the vertical direction of the building by being fixed to the above-mentioned waist edge 19 by nailing or the like. Here, the symbols 10a and 10b are used for convenience of explanation, and are the same as the wall material.

Referring to FIG. 3, a wall material 10 constructed as an exterior material will be described.
By embossing such as pressing, the convex region unit 16 is surrounded by the joint pattern 15 on the decorative surface 12.
In the present embodiment, a tiled pattern will be described as an example of the convex region unit 16. When the convex region unit 16, for example, the lower ridgeline 16a is substantially diagonally striped, the decorative pattern 16b is formed. The decorative pattern on the surface of the convex area unit 16 which is disposed near the center of the front surface 12 and is adjacent to the substantially right oblique stripe pattern 16b is also substantially left oblique stripe pattern 16c, substantially There are a parallel stripe pattern 16d and a substantially vertical stripe pattern 16e, each of which is formed of a substantially parallel stripe pattern in a direction different from the right oblique stripe pattern 16b. Further, as shown by M and N in FIG. 2, the width of the oblique stripes, the pitch of the oblique stripes, or the stripes of one or both of the approximately right oblique stripes and the approximately left oblique stripes is changed. When it is changed to a diagonal stripe line having a change such as a waveform, an effect of further changing the color tone and the shade of the color occurs, and the decorativeness can be further enhanced. In addition, by embossing, pressing, or the like, embossing processing, from the convex surface of the substantially parallel concave / convex decorative pattern 16 formed on the surface of the convex area provided on the decorative surface to the surface of the joint pattern 15. The larger the embossing (depth) dimension α is, the greater the effect of the change of the reflected light is. However, α is 1.3 to 3.5 mm depending on the material of the thin metal plate due to the limit of ductility and malleability. It is said.
